NAME

       tin, rtin - Usenet newsreader

SYNOPSIS

       tin [[-h|-H|-V] | [[[-a] [-dlnq|-Q] [-ArzxX]] [[-R|-S] -s News_dir] [-cuvZ] [-4|-6] [-N|-M
       address] [-o|-w]] [-D debug_level] [-G article_limit] [-f  newsrc_file]  [-g  server]  [-m
       Mail_dir] [-p port] [-I index_dir] [newsgroup[,...]]]

DESCRIPTION

       tin  is  a  full-screen  easy  to  use  Usenet newsreader. It can read news locally (e.g.,
       /var/spool/news) or remotely (rtin or tin -r option) via a NNTP  (Network  News  Transport
       Protocol)  server.  It will automatically utilize NOV newsoverview(5) style index files if
       available locally or via the NNTP [X]OVER command (RFC2980, RFC3977).

       tin has four separate levels of operation: Selection level, Group level, Thread level  and
       Article  level.  Use  the Help ('h') command to view a list of the commands available at a
       particular level.

       On   startup    tin    will    show    a    list    of    the    newsgroups    found    in
       ${TIN_HOMEDIR:-"$HOME"}/.newsrc.  An arrow '->' or highlighted bar will point to the first
       newsgroup. Move to a group by using the terminal arrow keys (terminal dependent)  or  Down
       ('j')  and  Up  ('k').  Use  PgUp/PgDn  (terminal dependent) or PageUp ('^U') (CTRL-U) and
       PageDown ('^D') (CTRL-D) to page up/down. Enter a newsgroup by pressing '<CR>'.

       The GroupNextUnreadArtOrGrp ('<TAB>') key enters the next newsgroup with unread articles.

OPTIONS

       -4          Force connecting via IPv4 to the remote NNTP server. Only available when build
                   with IPv6 support.

       -6          Force connecting via IPv6 to the remote NNTP server. Only available when build
                   with IPv6 support.

       -a          Toggle ANSI color (default is off).

       -A          Force authentication on initial connect. Only available when reading via NNTP.

       -c          Create/update index files for every group  in  ${TIN_HOMEDIR:-"$HOME"}/.newsrc
                   or file specified by the ''-f'' option and mark all articles as read.

       -d          Don't  load newsgroup descriptions and servers message of the day (interactive
                   mode).

       -D debug-level
                   Enter debug-level (1 = NNTP, 2 = filter, 4 =  newsrc,  8  =  threading,  16  =
                   memory,  32  = attributes, 64 = misc, 128 = remove existing debug files).  For
                   NNTP-level ''-v'' controls the verbosity of the output.

       -f file     Use  the  specified  file  of   subscribed   to   newsgroups   in   place   of
                   ${TIN_HOMEDIR:-"$HOME"}/.newsrc.

       -g server   Use        the        server        and        newsrc       specified       in
                   ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable.  Only  available  when  reading  via
                   NNTP.

       -G article-limit
                   Limit  the  number of articles/group to retrieve from the server.  If article-
                   limit is > 0 not more than the last article-limit articles/group  are  fetched
                   from the server. If article-limit is < 0 tin will start fetching articles from
                   your first unread minus absolute value of article-limit. Default is  0,  which
                   means no limit.

       -h          Help listing all command-line options.

       -H          Brief introduction to tin that is also shown the first time it is started.

       -I dir      Directory   in   which   to   store   newsgroup   index   files.   Default  is
                   ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news.  This  option  has
                   no  effect  if tin retrieves its index files via NNTP and cache_overview_files
                   is turned off.

       -l          Get      number      of      articles      per      group       from       the
                   ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file.  If  reading  via
                   NNTP this is done with the  LIST  command  (RFC3977).  This  might  result  in
                   incorrect  article  counts  but is usually faster than the default which is to
                   read the  ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file  (either
                   directly  or via LIST) and then check the article count via NNTP GROUP command
                   (RFC3977) ''-ln''. If reading via NNTP and LIST COUNTS (RFC6048) is  available
                   that is used instead as it gives more accurate article counts.

       -m dir      Mailbox directory to use. Default is ${TIN_HOMEDIR:-"$HOME"}/Mail.

       -M user     Mail unread articles to specified user for later reading. For more information
                   read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

       -n          Only              load              groups              from               the
                   ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file that are subscribed
                   to in the user's ${TIN_HOMEDIR:-"$HOME"}/.newsrc.  This  allows  a  noticeable
                   speedup  when connecting via a slow line, but tin may not be able detect which
                   groups are moderated. See also ''-l''.

       -N          Mail unread articles to yourself for later reading. For more information  read
                   section "AUTOMATIC MAILING AND SAVING NEW NEWS".

       -o          Quick  post  all  postponed  articles and exit. In order for this to be really
                   quick, it should be used with ''-n'' if possible.

       -p port     Port to use if reading via NNTP (default is  119).  This  also  overrides  the
                   environment variable $NNTPPORT if set. Only available when reading via NNTP.

       -q          Don't  check  for  new  newsgroups and skip loading the servers message of the
                   day.

       -Q          Quick start. Start tin as quickly as possible. Currently this is equivalent to
                   ''-nqd''.

       -r          Read  news  remotely from the default NNTP server specified in the environment
                   variable $NNTPSERVER or contained in the file /etc/news/server.

       -R          Read news saved by the ''-S'' option.

       -s dir      Save/read articles to/in directory. Default is ${TIN_HOMEDIR:-"$HOME"}/News.

       -S          Save unread articles  for  later  reading  by  the  ''-R''  option.  For  more
                   information read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

       -u          Create/update  index  files for every group in ${TIN_HOMEDIR:-"$HOME"}/.newsrc
                   or file specified by the  ''-f''  option.  This  option  is  disabled  if  tin
                   retrieves its index files via a NNTP server and cache_overview_files is turned
                   off.

       -v          Verbose mode for ''-D'', ''-c'', ''-M'', ''-N'',  ''-S'',  ''-u''  and  ''-Z''
                   options. Can be used multiple times to increase verbosity.

       -V          Print version and date information.

       -w          Quick  mode  to  post an article and then exit. This option implies ''-d''. In
                   order for this to be really quick, it should be used with ''-n'' if possible.

       -x          No-posting mode. You cannot post articles if you use this option.

       -X          No   overwrite   mode.   ${TIN_HOMEDIR:-"$HOME"}/.newsrc    and    files    in
                   ${TIN_HOMEDIR:-"$HOME"}/.tin  will  not  be  overwritten but may be created if
                   they don't exist.

       -z          Only start tin if there is any new/unread news. If  there  is  news  tin  will
                   position  cursor  at first group with unread news. Useful for putting in login
                   file.

       -Z          Check if there is any new/unread news and exit  with  appropriate  status.  If
                   ''-v''  option  is  specified  the  number of unread articles in each group is
                   printed. An exit code 0 indicates no news, 1 that an error occurred and 2 that
                   new/unread news exists. Useful for writing scripts.

       tin  can  also dynamically change its options by the OptionMenu ('M') command. Any changes
       are written  to  ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.  For  more  information  see  section
       "GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES" and tin(5).

       A list of groups can be specified after the other command-line options. This can be useful
       if you wish to yank in or subscribe to a hand-picked subset of the active newsgroups.  See
       the section "NEWSGROUP LISTS & WILDCARDS" for the types of pattern that tin understands.

       If  you  specify  a single group-name, or a wildcard that matches a single group, then you
       will automatically enter that group. Otherwise the  normal  group  selection  screen  will
       appear,  but with all the matching groups present too, as though you had yanked just those
       groups in.

       With the ''-w'' flag a given group-name is used as default group to post to. If more  than
       one  group  or  a  wildcard is specified only the first group respectively the first group
       that matches is used.

       Once   you   use   SelectYankActive   ('y')   to   yank   in   all   active   groups,   or
       SelectToggleReadDisplay  ('r')  to  toggle  the  read/unread status, then the command-line
       groups  will  be  gone.  You  can   use   SelectSyncWithActive   ('Y')   to   reread   the
       ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file and get them back.

       NB:  With the ''-n'' flag, only unsubscribed groups in the ${TIN_HOMEDIR:-"$HOME"}/.newsrc
       file  (or  the  newsrc-file   given   by   the   ''-f''   command-line   switch   or   via
       ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable) can be matched.

       Command-line  options  have  higher  priority  than  attributes  and tinrc options.  Thus,
       command-line option takes precedence over configured values.

USAGE

   NEWS ADMINISTRATION
       Maintaining Netnews on large networks of machines can be a pretty time consuming job as  I
       discovered when I was given the job of maintaining our news system and news users.

       A  user  starting  tin  for  the  first  time can be automatically subscribed to a list of
       newsgroups that are deemed appropriate by the news administrator. The  subscriptions  file
       should      be      created      in      your      news      lib      directory     (i.e.,
       ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions) and should be world readable. If  you  read  news
       via NNTP, then your news server must support the LIST SUBSCRIPTIONS command. It is part of
       the NNTP List Extensions (RFC6048) and all modern servers should understand it.

   SCREEN FORMAT
       tin has four separate levels of operation: Selection level, Group level, Thread level  and
       Article level.

       At  the Selection level the title displays (the name of the news server and) the number of
       subscribed groups (containing new unread articles). The newsgroups are  displayed  in  the
       middle of the screen usually with the number of unread articles displayed on the same line
       in front, but it can be customized via select_format.

       There may also be a character prefixing the line. An explanation follows:

       u         This group  is  unsubscribed.  To  see  only  your  subscribed  groups  use  the
                 SelectToggleReadDisplay ('r') or SelectYankActive ('y') toggle keys.

       M         This  is  a  moderated group. Any posts you make will have to be approved by the
                 group administrator before it will be made public. tin will ask for confirmation
                 before you post to a moderated group.

       N         This  is  a  new  newsgroup  which has been created since you last used tin. New
                 newsgroups are not subscribed to by default (However, see the  $AUTOSUBSCRIBE  /
                 $AUTOUNSUBSCRIBE  environment  variables).  Subscribe to it in the normal way if
                 you wish the group to continue to appear in your Selection Menu.  Simply  ignore
                 new  newsgroups and they will be gone the next time you start tin. You will have
                 to yank in all the groups to find them in a later session.

       D         This group no longer exists. If you no  longer  wish  to  see  this  group  then
                 unsubscribe  from  it  in the normal way. This flag will only appear if you have
                 set strip_bogus to "ask" in the Options Menu.

       X         You may no longer make posts to this group. Often a group will be superseded  by
                 a more appropriately named one.

       =         This  group  has  been renamed and you may no longer post to it. If you do, then
                 you will receive an error from your news server telling you the correct group to
                 post to.

       At  the  Group  level the title contains the name of the group, the number of conversation
       threads, the abbreviated threading method (thread_articles), the limit of articles to  get
       (if  set;  getart_limit),  the  total  number  of  (unread)  articles  (art_marked_read or
       art_marked_unread), the number of hot articles art_marked_selected, the number of read hot
       articles   (if   any;   art_marked_read_selected),   the   number   of   recent   articles
       (art_marked_recent) and the number of killed articles (art_marked_killed). I.e.:

                   alt.sources (5B -50/23+ 0* 3o 0K)

       The characters after the numbers are depending to the configuration and  if  your  are  in
       show_only_unread_arts mode or not. Some numbers could be missing if the specific option is
       not enabled. It might also contain an 'M', 'X' or '=' (see above; doesn't  work  with  the
       ''-n''  command-line  switch!) if the group is moderated, set to no posting or postings to
       it get redirected.

       If a thread has unread articles it is marked with art_marked_unread in front of the  total
       number  of articles in the thread. If there are recent articles within the thread it might
       be marked with art_marked_recent in front of the total number of articles in the thread  —
       this is controlled by the recent_time option. If a thread has hot articles in it (see also
       section "FILTERING ARTICLES") it's marked with art_marked_selected in front of  the  total
       number of articles in the thread. The number of lines of the first (unread) article in the
       thread might also be shown right before the subject — this is controlled by the  show_info
       option. The display can be customized via group_format.

   COMMON EDITING COMMANDS
       An  emacs(1)  style  editing  package allows the easy editing of input strings.  A history
       list allows the easy reuse of previously entered strings.  In addition to the cursor keys,
       the following commands are available when editing a string:

       ^A, ^E    move to beginning or end of line, respectively.

       ^F, ^B    non-destructive move forward or back one location, respectively.

       ^D        delete the character currently under the cursor, or send EOF if no characters in
                 the buffer.

       ^H, <DEL> delete character left of the cursor.

       ^K        delete from cursor to end of line.

       ^P, ^N    move through history, previous and next, respectively.

       ^L, ^R    redraw the current line.

       <CR>      places line on history list if non-blank, appends newline  and  returns  to  the
                 caller.

       <ESC>     aborts the present editing operation.

   GLOBAL COMMANDS
       The following commands are available at all 4 menu levels and always have the same effect.

       ShellEscape '!'
                 Shell  escape.  ShellEscape by itself will launch a shell, ShellEscape <command>
                 will run an external <command>. This facility may  have  been  disabled  by  the
                 System Administrator.

       ToggleColor '&'
                 Toggle use of ANSI color.

       RedrawScr '^L'
                 Redraw the current screen.

       ScrollUp '<'
                 Scroll screen up by one line.

       ScrollDown '>'
                 Scroll screen down by one line.

       Postponed 'O' '^O'

                 GroupMarkUnselArtRead, one can then do GroupUndoSel to reset articles. Thus, one
                 can iteratively whittle down uninteresting threads.

       is   read   from   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.  The  global  file  is  useful  for
       distributing system-wide defaults to new users who have no private tinrc yet.

       The  variables  are  user  configurable  by   editing   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc
       directly.  Most  of  them  can also be set in the GLOBAL OPTIONS MENU which is accessed by
       pressing OptionMenu ('M') at all levels. It allows the user to customize the  behavior  of
       tin.  The  options  are saved to the file ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc when you exit
       tin so don't edit the file directly whilst tin is running.

       In the options menu use the cursor keys in the usual way to move around. Use  ConfigSelect
       ('^J'  or  '<CR>')  to  'open' the option you wish to change. You will need to enter a new
       value or use '<SPACE>' to toggle the available options. ConfigSelect  will  save  the  new
       value, '<ESC>' will abort without saving changes.

       As  with the other menus, RedrawScr ('^L') will redraw the screen. You can use SearchSubjF
       ('/'), SearchSubjB ('?') and SearchRepeat ('\') to search for a specific option. Use  Quit
       ('q')  to  exit  the  option menu and keep your changes. Use QuitTin ('Q') to exit without
       keeping your changes.

       The options menu provides access to the attributes menu  for  the  current  group  by  the
       ConfigToggleAttrib  ('<TAB>')  command.  Pressing ConfigToggleAttrib again toggles back to
       the options menu. For more information see section "ATTRIBUTES MENU AND GROUP ATTRIBUTES".

       The ConfigScopeMenu ('S') command brings up the scopes  menu.  For  more  information  see
       section "SCOPES MENU".

       Here  is a full list of all the available variables. The name in braces is the name of the
       corresponding setting in ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.

       Detection of external quotes (extquote_handling)
           If ON quotes from external sources will be detected. Default is OFF.

       Regex used to show external quotes (extquote_regex)
           A regular expression that will be applied when reading articles.  All  matching  lines
           are  shown  in  col_extquote.  If  extquote_regex  is  blank, then tin uses a built-in
           default.

       Force redraw after certain commands (force_screen_redraw)
           Specifies whether a screen  redraw  should  always  be  done  after  certain  external
           commands. Default is OFF.

       Number of articles to get (getart_limit)
           If  getart_limit is > 0 not more than the last getart_limit articles/group are fetched
           from the server. If getart_limit is < 0 tin will start  fetching  articles  from  your
           first unread minus absolute value of getart_limit. Default is 0, which means no limit.

           combination  of  PageDown  and  PageNextUnread.  When PageDown is set tin jumps to the
           next article at the end of the current one.  When  PageNextUnread  is  set  tin  jumps
           immediately  to  the next article when PageNextUnread ('<TAB>') is pressed. Default is
           PageNextUnread.

       Display uue data as an attachment (hide_uue)
           If set to 'No' then raw uuencoded data is displayed. If set to 'Yes' then sections  of
           uuencoded  data  will  be  shown  with a single tag line showing the size and filename
           (much the same as a MIME attachment).  If set to 'Hide all' then any line  that  looks
           like uuencoded data will be folded into a tag line. This is useful when uuencoded data
           is split across more than one article but can  also  lead  to  false  positives.  This
           setting can also be toggled in the article viewer.  Default is 'No'.

       External inews (inews_prog)
           Path,  name and options of external inews(1).  If you are reading via NNTP the default
           value is "--internal" (use built-in NNTP inews), else it is "inews -h". The article is
           passed to inews_prog on STDIN via '< article'.

       (info_in_last_line)
           If  ON, show current group description or article subject in the last line (not in the
           pager and global menu) — ToggleInfoLastLine ('i') toggles setting.  This  facility  is
           useful  as the full width of the screen is available to display long subjects. Default
           is OFF.

       Use interactive mail reader (interactive_mailer)
           Interactive mailreader: if greater than 0 your mailreader will be invoked earlier  for
           reply  so  you  can  use  more  of its features (e.g. MIME, pgp, ...). 1 means include
           headers, 2 means don't include headers (old use_mailreader_i=ON option). 0  turns  off
           usage. This option has to suit mailer_format. Default is 0.

       Use inverse video for page headers (inverse_okay)
           If ON use inverse video for page headers and URL highlighting.  Default is ON.

       Keep failed arts in ~/dead.articles (keep_dead_articles)
           If  ON  keep  all  failed  postings  in  ${TIN_HOMEDIR:-"$HOME"}/dead.articles besides
           keeping the last failed posting in  ${TIN_HOMEDIR:-"$HOME"}/dead.article.  Default  is
           ON.

       Filter which articles (kill_level)
           This  option  controls  the processing and display of articles that are killed.  There
           are 3 options:

            0  Kill only unread arts is the 'traditional' behavior of tin. Only  unread  articles
               are  killed  once  only  by marking them read. As filtering only happens on unread
               articles with kill_level set to 0, art_marked_killed and  art_marked_read_selected
               are only shown once. When you reenter the group the mark will be gone.

            1  Kill  all  arts & show with K will process all articles in the group and therefore
               there is a processing  overhead  when  using  this  option.  Killed  articles  are
               threaded as normal but they will be marked with art_marked_killed.

            2  Kill  all arts and never show will process all articles in the group and therefore
               there is a processing overhead when using this option. Killed articles simply does
               not get displayed at all.
       Default is 0 (Kill only unread arts).

       Use 8bit characters in mail headers (mail_8bit_header)
           Allows  8bit  characters  unencoded  in  the  header  of mail message. Default is OFF.
           Turning it ON is effective only if mail_mime_encoding is also set to 8bit. Leaving  it
           OFF  is  safe for most users and compliant to Internet Mail Standard (RFC5322 and RFC‐
           2047). Default is OFF.

       Mail address (mail_address)
           User's mail address (and full name), if not username@host. This is used when  creating
           articles, sending mail and when pgp(1) signing.

       MIME encoding in mail messages (mail_mime_encoding)
           MIME   encoding   of   the   body   in  mail  message,  if  necessary  (8bit,  base64,
           quoted-printable, 7bit). Default is quoted-printable.

       Quote line when mailing (mail_quote_format)
           Format of quote line when replying (via mail)  to  an  article  (%A=Address,  %D=Date,
           %F=Fullname+Address,    %G=Groupname,    %M=Message-ID,   %N=Fullname,   %C=Firstname,
           %I=Initials). Default is "In article %M you wrote:"

       Format of the mailbox (mailbox_format)
           Select one of the following mailbox-formats: MBOXO (default, except on SCO), MBOXRD or
           MMDF  (default  on  SCO). See mbox(5) and RFC4155 for more details on MBOXO and MBOXRD
           and mmdf(5) for more details about MMDF.

       Mail directory (maildir)
           The directory where articles/threads are to be saved in mbox(5) format.  This  feature
           is  mainly  for  use  with  the  elm(1)  mail  program.  It  allows  the  user to save
           articles/threads/groups simply by giving '=' as the filename to save to.   Default  is
           ${TIN_HOMEDIR:-"$HOME"}/Mail.

       Invocation of your mail command (mailer_format)
           The  format  string used to create the mailer command with parameters that is used for
           mailing articles to other people. Default is '%M "%T" < %F' (e.g., /bin/mail "iain"  <
           .article).  The  flexible  format  allows  other  mailers  with different command line
           parameters to be used such as
              sendmail -oem -t < %F
              elm -s "%S" "%T" < "%F"
              claws-mail --compose "mailto:%T?subject=%S&insert=%F"
           interactive_mailer must be set adequate. The following substitutions are supported:
              %F              filename
              %M              default_mailer
              %S              subject-field
              %T              to-filed
              %U              username
              %%              %

       'Mark as (un)read' ignores tags (mark_ignore_tags)
           When this is ON, the GroupMarkThdRead ('K'),  ThreadMarkArtRead  ('K'),  MarkThdUnread
           ('Z')  at  Group level and MarkArtUnread ('z') at Thread level functions mark just the
           current article or thread, ignoring other tagged, (un)read  articles.  When  OFF,  the
           same  function  presents  a  menu  with  choices of the current thread or article, all
           tagged, unread articles, or nothing.

       Mark saved articles/threads as read (mark_saved_read)
           If ON mark articles that are saved as read. Default is ON.

       Viewer program for MIME articles (metamail_prog)
           Path, name and options of external metamail(1) program used to view non-textual  parts
           of articles.  To use the built-in viewer, set to --internal. This is the default value
           when metamail(1) is not installed. Leave it blank if  you  don't  want  any  automatic
           viewing  of  non-textual  attachments.  The 'V' command can always be used to manually
           view any attachments. See also ask_for_metamail.

       MM_CHARSET (mm_charset)
           Charset supported locally, which is also used for MIME header (charset  parameter  and
           charset  name in header encoding) in mail and news postings. If MIME_STRICT_CHARSET is
           defined at compile time, text in charset other than the value  of  this  parameter  is
           considered  not  displayable and represented as '?'. Otherwise, all character sets are
           regarded as compatible with the display. If it's not set, the value of the environment
           variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither
           of them is defined. If your system supports iconv(3), this option is disabled and  you
           should use mm_network_charset instead.

       MM_NETWORK_CHARSET (mm_network_charset)
           Charset  used  for  posting and MIME headers; replaces mm_charset.  Conversion between
           mm_network_charset and local charset  (determined  via  nl_langinfo(3))  is  done  via
           iconv(3), if this function is not available on your system this option is disabled and
           you have to use mm_charset instead.  mm_network_charset  is  limited  to  one  of  the
           following charsets:
              US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU} EUC-{CN,JP,KR,TW},
              ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
           Not all values might work on your system, see iconv_open(3) for more details. If  it's
           not  set,  the  value  of  the  environment  variable $MM_CHARSET is used. US-ASCII or
           compile-time default is used in case neither of them is defined.

       Attribute of highlighting with _dash_ (mono_markdash)
           Character attribute of words emphasized like _this_. It depends on your terminal which
           attributes are usable. See also word_h_display_marks and word_highlight.

       Attribute of highlighting with /slash/ (mono_markslash)
           Character attribute of words emphasized like /this/. It depends on your terminal which
           attributes are usable. See also word_h_display_marks and word_highlight.

       Attribute of highlighting with *stars* (mono_markstar)
           Character attribute of words emphasized like *this*. It depends on your terminal which
           attributes are usable. See also word_h_display_marks and word_highlight.

       Attribute of highlighting with -stroke- (mono_markstroke)
           Character attribute of words emphasized like -this-. It depends on your terminal which
           attributes are usable. See also word_h_display_marks and word_highlight.

       (newnews)
           These are internal timers used by tin to keep track of new newsgroups.  Do not  change
           them unless you understand what they are for.

       Display these header fields (or *) (news_headers_to_display)
           Which news headers you wish to see. If you want to see _all_ the headers, place an '*'
           as this value. This is the only way a wildcard can be used.  If you enter 'X-' as  the
           value,  you  will see all headers beginning with 'X-' (like X-Alan or X-Pape). You can
           list more than one by delimiting with spaces. Not defining  anything  turns  off  this
           option.

       Do not display these header fields (news_headers_to_not_display)
           Same  as  news_headers_to_display  except it denotes the opposite. An example of using
           both options might be if you thought 'X-' headers were A Good Thing(tm),  but  thought
           Alan  and  Pape  were  miscreants...  well  then  you  would  do  something like this:
           news_headers_to_display=X-  news_headers_to_not_display=X-Alan  X-Pape  Not   defining
           anything turns off this option.

       Quote line when following up (news_quote_format)
           Format  of  quote  line  when  posting/following  up  an article (%A=Address, %D=Date,
           %F=Fullname+Address,   %G=Groupname,   %M=Message-ID,    %N=Fullname,    %C=Firstname,
           %I=Initials). Default is "%F wrote:".

       NNTP read timeout in seconds (nntp_read_timeout_secs)
           Time  in seconds to wait for a response from the server. Default is 120.  Setting this
           to 0 means no timeout.

       Unicode normalization form (normalization_form)
           The normalization form tin should use to normalize unicode input.  The possible values
           are:

            0  None: no normalization

            1  NFKC: Compatibility Decomposition, followed by Canonical Composition

            2  NFKD: Compatibility Decomposition

            3  NFC: Canonical Decomposition, followed by Canonical Composition

            4  NFD: Canonical Decomposition

            5  NFKC_CF:  Compatibility  Decomposition, followed by Canonical Composition and Case
               Folding
       Some normalization modes are only available if they are supported by the library tin  uses
       to do the normalization. NFC should be used if possible.

       Go to first unread article in group (pos_first_unread)
           If  ON  put cursor at first unread article in group otherwise at last article. Default
           is ON.

       Use 8bit characters in news headers (post_8bit_header)
           Allows 8bit characters unencoded in the header of a news article,  if  set  this  also
           disables  the  generation  of  MIME-headers when they are usually required. Default is
           OFF. Only enacted if post_mime_encoding is also set to 8bit.  In  a  number  of  local
           hierarchies  where  8bit characters are used, using unencoded (raw) 8bit characters in
           header is acceptable and sometimes even recommended so that  you  need  to  check  the
           convention  adopted  in  the  local hierarchy of your interest to determine what to do
           with this and post_mime_encoding.

       MIME encoding in news messages (post_mime_encoding)
           MIME  encoding  of  the  body  in  news  message,   if   necessary.   (8bit,   base64,
           quoted-printable,  7bit).  Default  is  8bit,  which leads to no encoding.  base64 and
           quoted-printable are usually undesired on usenet.

       View post-processed files (post_process_view)
           If ON, then tin will start an appropriate viewer program to  display  any  files  that
           were  post  processed  and  uudecoded.  The program is determined using the mailcap(5)
           file. Default is ON.

       Post process saved articles (post_process_type)
           This specifies whether to perform post processing on saved  articles.   The  following
           values are allowed:

            0  No (default), no post processing is done.

            1  Shell archives, unpacking of multi-part shar(1) files only.

            2  Yes, binary attachments and data will be decoded and saved.

       Filename to be used for storing posted articles (posted_articles_file)
           Keep  posted  articles  in  ${TIN_HOMEDIR:-"$HOME"}/Mail/posted_articles_file.   If no
           filename is set then postings will not be saved.  Default is 'posted'.

       Print all headers when printing (print_header)
           If ON, then the full article header  is  sent  to  the  printer.  Otherwise  only  the
           ''Subject:'' and ''From:'' fields are output. Default is OFF.

       Printer program with options (printer)
           The printer program with options that is to be used to print articles.  The default is
           lpr(1) for BSD machines and lp(1) for SysV machines. Printing from tin may  have  been
           disabled by the System Administrator.

       Process only unread articles (process_only_unread)
           If  ON  only save/print/pipe/mail unread articles (tagged articles excepted).  Default
           is OFF.

       Show empty Followup-To in editor (prompt_followupto)
           If ON show empty ''Followup-To:'' header when editing an article. Default is OFF.

       Characters used as quote-marks (quote_chars)
           The character used in quoting included text to article followups and mail replies. The
           '_' character represents a blank character and is replaced with ' ' when read. Default
           is '>_'.

       Quoting behavior (quote_style)
           How articles should be quoted when following up or  replying  to  them.  There  are  a
           number of things that can be done: empty lines can be quoted, signatures can be quoted
           and quote_chars can be compressed when quoting multiple times (for example,  '>  >  >'
           will  be  turned  into  '>>>').  The default is to compress quotes, and to quote empty
           lines.
           When you are viewing an article in raw mode ('^H'), and follow up or reply to it,  the
           signature  will  be  quoted  even if it would otherwise not be.  If show_signatures is
           off, then the signature will never be quoted.

       Regex used to show quoted lines (quote_regex)
           A regular expression that will be applied when reading articles.  All  matching  lines
           are shown in col_quote. If quote_regex is blank, then tin uses a built-in default.

           A regular expression that will be applied when reading articles.  All  matching  lines
           are shown in col_quote3. If quote_regex3 is blank, then tin uses a built-in default.

       Article recentness time limit (recent_time)
           If  set  to  0,  this  feature  is deactivated, otherwise it means the number of days.
           Default is 2.

       Render BiDi (render_bidi)
           If ON tin does the rendering of bi-directional text. If OFF tin leaves  the  rendering
           of bi-directional text to the terminal. Default is OFF.

       Interval in seconds to reread active (reread_active_file_secs)
           The  news  ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file  is  reread  at
           regular intervals to show if any new news has arrived. Default is 1200.  Setting  this
           to 0 will disable this feature.

       Directory to save arts/threads in (savedir)
           Directory where articles/threads are saved. Default is ${TIN_HOMEDIR:-"$HOME"}/News.

       Score limit (kill) (score_limit_kill)
           If  the  score  of  an article is below or equal this value the article gets marked as
           killed.

       Score limit (select) (score_limit_select)
           If the score of an article is above or equal this value the  article  gets  marked  as
           hot.

       Default score to kill articles (score_kill)
           Score of an article which should be killed, this must be <= score_limit_kill.

       Default score to select articles (score_select)
           Score of an article which should be marked hot, this must be >= score_limit_select.

           The  number  of  lines  that  will be scrolled up/down in the article pager when using
           cursor-up/down. The default is 1 (line-by-line). Set to 0 to get traditional tin page-
           by-page  scrolling.  Set to -1 to get page-by-page scrolling where the top/bottom line
           is   carried    over    onto    the    next    page.     This    setting    supersedes
           show_last_line_prev_page=ON.  Set  to  -2  to  get  half-page  scrolling. This setting
           supersedes full_page_scroll=OFF.

           The path that specifies the signature file to use when posting,  following  up  to  or
           replying to an article. If the path is a directory then the signature will be randomly
           generated from files that are in the specified directory. If the path starts with a  !
           the  program  the path points to will be executed to generate a signature. In order to
           pass the group name to the program, %G can be specified. This will be replaced by  the
           name  of  the  current  newsgroup.  --none  will  suppress  any signature.  Default is
           ${TIN_HOMEDIR:-"$HOME"}/.Sig.

       Add signature when reposting (signature_repost)
           If ON add signature to reposted articles. Default is ON.

       Regex used to highlight /slashes/ (slashes_regex)
           A regular expression that will be applied when reading articles.  All  matching  words

       Spamtrap warning address parts (spamtrap_warning_addresses)
           Set this option to a list of comma-separated strings to be warned if you are  replying
           to  an  article  by  mail  where the e-mail address contains one of these strings. The
           matching is case-insensitive. Example:

           spam,delete,remove

       Regex used to highlight *stars* (stars_regex)
           A regular expression that will be applied when reading articles.  All  matching  words
           are  shown  in col_markstar or mono_markstar. If stars_regex is blank, then tin uses a
           built-in default.

       Start editor with line offset (start_editor_offset)
           Set ON if the editor used for posting, follow-ups and bug reports has  the  capability
           of  starting  and positioning the cursor at a specified line within a file. Default is

           that no longer exist on the news server. There are 3 options. 0  means  do  nothing  &
           always  keep  bogus groups.  1 means bogus groups will be permanently removed. 2 means
           that bogus groups will appear on the Group Selection Menu, prefixed with a  'D'.  This
           allows you to unsubscribe from them as and when you wish. Default is 0 (Always Keep).

           also  previous  unread articles. If disabled the search stops at the end of the thread
           list. Default is ON.

       Display "a as Umlaut-a (tex2iso_conv)
           If ON, show "a as Umlaut-a, etc. Default is OFF. This behavior can also be toggled  in
           the article viewer via PageToggleTex2iso ('"').

       Thread articles by (thread_articles)
           Defines  which  threading  method to use. It's possible to set the threading type on a
           per group basis by setting the group attribute variable thread_arts to 0 –  4  in  the
           file  ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes.  (See  also  "GROUP  ATTRIBUTES".)  The
           default is Both Subject and References.  The choices are:

            0  None, don't thread.

            1  Subject, thread on ''Subject:'' only.

            2  References, thread on ''References:'' only.

            3  Both  Subject  and  References,  thread  on  ''References:''   then   ''Subject:''
               (default).

            4  Multipart Subject, thread multipart articles on ''Subject:''.

            5  Percentage Match, thread base upon a partial character match on ''Subject:''.

       Catchup thread by using left key (thread_catchup_on_exit)
           If ON catchup group/thread when leaving with the left arrow key. Default is ON.

       Format string for the Thread level (thread_format)
           Format  string  tin uses for Thread level representation. See the section "CUSTOMIZING
           THE SCREEN FORMAT". Default is "%n %m  [%L]  %T  %F".

       Matchingness of a thread (thread_perc)
           How closely the subjects must match for two threads to be considered part of the  same
           thread. This is a percentage and the default if 75%.

       Score of a thread (thread_score)
           How  the  total score of a thread is computed. Default is 0, the maximum score in this
           thread.

            0  Max, the maximum score in this thread.

            1  Sum, the sum of all scores in this thread.

            2  Average, the average score in this thread.

       Transliteration (translit)
           If  ON  append  //TRANSLIT  to  the  first  argument  of   iconv_open(3)   to   enable
           transliteration.  This means that when a character cannot be represented in the target
           character set, it can  be  approximated  through  one  or  several  similarly  looking
           characters.  On  systems  where this extension doesn't exist, this option is disabled.
           Default is OFF.

       How to treat blank lines (trim_article_body)
           Allows you to select how tin treats blank lines in article bodies.  Default is 0. This
           option does not affect lines within verbatim blocks.

            0  Don't trim article body, do nothing.

            1  Skip leading blank lines.

            2  Skip trailing blank lines.

            3  Skip leading and trailing blank l., skip leading and trailing blank lines.

            4  Compact  multiple  between  text,  replace multiple blank lines between textblocks
               with one blank line.

            5  Compact multiple and skip leading, 4 + 1

            6  Compact multiple and skip trailing, 4 + 2

            7  Compact mltpl., skip lead. & trai., 4 + 3

       Regex used to highlight _underline_ (underscores_regex)
           A regular expression that will be applied when reading articles.  All  matching  words
           are  shown  in  col_markdash or mono_markdash. If underscores_regex is blank, then tin
           uses a built-in default.

       Remove ~/.article after posting (unlink_article)
           If ON remove ~/.article after posting. Default is ON.

       Program that opens URLs (url_handler)
           The program that will  be  run  when  launching  URLs  in  the  article  viewer  using
           PageViewUrl  ('U'). The actual URL will be appended to this. Default is url_handler.pl
           %s.

       URL highlighting in message body (url_highlight)
           Enable highlighting URLs in message body. Default is ON.

       Use ANSI color (use_color)
           If enabled tin uses ANSI-colors. Default is OFF.

       Use scroll keys on keypad (use_keypad)
           Default is OFF.

       Use mouse in xterm (use_mouse)
           Allows the mouse button support in a xterm(1x) to  be  enabled/disabled.   Default  is
           OFF.

       Use slrnface to show ''X-Face:''s (use_slrnface)
           If  enabled  tin uses slrnface(1) to interpret the ''X-Face:'' header. For this option
           to have any effect, tin must be running in a xterm(1x) and slrnface(1) must be in your
           $PATH. Default is OFF.

       Use UTF-8 graphics (utf8_graphics)
           If  ON  use UTF-8 characters for indicator ('->'), thread/attachment tree and ellipsis
           ('...'). Default is OFF.

       Regex for begin of a verbatim block (verbatim_begin_regex)
           A regular expression that tin will use to find the begin of a verbatim block.

       Regex for end of a verbatim block (verbatim_end_regex)
           A regular expression that tin will use to find the end of a verbatim block.

       Detection of verbatim blocks (verbatim_handling)
           If ON verbatim blocks will be detected. Default is ON.

       Wildcard matching (wildcard)
           Allows you to select how tin matches strings. The default is 0 and  uses  the  wildmat
           notation,  which is how this has traditionally been handled.  Setting this to 1 allows
           you to use perl(1) compatible regular expressions  pcre(3)  (see  also  perlre(1)  and
           pcrepattern(3)).   You  will  probably want to update your filter file if you use this
           regularly.  NB: Newsgroup names will always be matched using the wildmat notation.

       What to display instead of mark (word_h_display_marks)
           Should the leading and ending stars, slashes, strokes and dashes  also  be  displayed,
           even when they are highlighting marks?

            0  no

            1  yes, display mark

            2  print a space instead

       Word highlighting in message body (word_highlight)
           Enable  word  highlighting.  See  word_h_display_marks  for  the options available. If
           use_color is enabled the colors specified in col_markdash, col_markslash, col_markstar
           and  col_markstroke  are  used  for  word  highlighting  else the character attributes
           specified in mono_markdash,  mono_markslash,  mono_markstar  and  mono_markstroke  are
           used. Default is ON.

       Page line wrap column (wrap_column)
           Sets the column at which a displayed article body should be wrapped.  If this value is
           equal to 0, it defaults to the current screen width.  If this value  is  greater  than
           your  current  screen  width  the  part off-screen is not displayed. Thus setting this
           option to a large value can be used to disable wrapping. If this value is negative the
           wrap margin is the current screen width plus the given value (as long as the result is
           still positive, otherwise it will fall back to the current screen width).  Default  is
           0, wrapping at the current screen width.

       Quote line when crossposting (xpost_quote_format)
           Format  is  the  same  as  for  news_quote_format,  this  is  used when answering to a
           crossposting to several groups with no ''Followup-To:'' set.

   ATTRIBUTES MENU AND GROUP ATTRIBUTES
       tin allows certain attributes to be set on a per group basis. If  it  exists,  the  global
       attributes  file, ${TIN_LIBDIR:-NEWSLIBDIR}/attributes is read. After that, the user's own
       attributes file ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes is read.   The  global  attributes
       file  is  useful  for  distributing  system-wide defaults to new users who have no private
       attributes file yet.

       Note that the scope=<grouplist> line  has  to  be  specified  before  the  attributes  are
       specified  for  that list. All attributes are set to a reasonable default so you only have
       to specify the attribute that you want to change (e.g., savedir).  All  toggle  attributes
       are  set  by specifying ON/OFF. Otherwise, these function exactly the same as their global
       equivalents. For more details see tin(5).

       Attributes can also be  changed  from  the  attributes  menu  which  can  be  accessed  by
       ConfigToggleAttrib  ('<TAB>')  from  the options menu or ScopeSelect ('^J' or '<CR>') from
       the scopes menu.  The attributes menu looks and behaves very similar to the options  menu.
       The title shows the current scope. Attributes set in the current scope are marked with '+'
       to the left of the attributes number.

       Besides the keys for moving around and changing values known from  the  options  menu  the
       attributes  menu  provides  the following command: ConfigResetAttrib ('r') which resets an
       attribute to a default value.

   SCOPES MENU
       The scopes menu (accessible from the options menu with ConfigScopeMenu  ('S'))  shows  all
       scopes  read from the global and local attributes file.  Scopes from the global attributes
       file are marked with '!' to the left of  the  scope  number.  Delete/rename/move  are  not
       possible with those scopes.

       In  addition  to  the common moving keys the following commands are available: ScopeSelect
       ('^J' or '<CR>') enter the attributes menu for the current scope,  ScopeEditAttributesFile
       ('E')  edit  the  local attributes file, ScopeAdd ('a') add a new scope, ScopeDelete ('d')
       delete the current scope, ScopeMove ('m') move  the  current  scope  to  a  new  position,
       ScopeRename  ('r') rename the current scope. ToggleHelpDisplay ('H') toggles the help mini
       menu at the bottom of the screen.

   FILTERING ARTICLES
       When there is a subject or an author which you are either  very  interested  in,  or  find
       completely uninteresting, you can easily instruct tin to auto-select or auto-kill articles
       that match rules that you specify. This can be anything from the name of the author to the
       number of lines in an article.

       When  tin  starts  up  the  user's kill-file ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (see also
       tin(5)) is read. Each time a newsgroup is entered  the  rules  are  applied  and  articles
       killed or selected when they meet certain criteria.

       The  degree  to which rules are applied depend on the kill_level tinrc setting. By default
       killed  articles  will  only  be  marked  read.  Adjust  kill_level  for  more  aggressive
       processing. Articles that match an auto-selection rule are marked with a ''*''.

       Filtering  rules  can  be  manually  entered into ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (but
       don't do this whilst running tin else you will lose your changes) or by using an on-screen
       menu within tin.

       The  filtering capabilities of tin have been significantly enhanced over previous versions
       to include scoring and better pattern matching. It is recommended that you read  the  file
       filtering in the tin documentation directory. This file can also be read online at
       <http://www.tin.org/filtering.txt>.

       The   on-screen   filtering   menu  is  accessed  by  pressing  MenuFilterKill  ('^K')  or
       MenuFilterSelect ('^A') at the Group and Article levels. It allows the  user  to  kill  or
       select  an  article that matches the current ''Subject:'' line, ''From:'' line or a string
       entered by the user. The user entered  string  can  be  applied  to  the  ''Subject:''  or
       ''From:'' line of an article. The filter can be limited to the current newsgroup or it can
       apply to all newsgroups. Once entered the user can abort the command and not save the  new
       filter, edit the full filter file or save filter.

   POSTING ARTICLES
       tin  allows  posting of articles, follow-up to already posted articles and replying direct
       through mail to the author of an article.

       Use the Post ('w') command to post an article to a newsgroup.   After  entering  the  post
       subject the default editor (i.e., vi(1)) or the editor specified by the $VISUAL or $EDITOR
       environment variable will be started and the article can be entered. To crosspost articles
       simply add a comma and the name of the newsgroup(s) to the end of the ''Newsgroups:'' line
       at the beginning of the article. After saving and exiting the editor you are asked if  you
       wish  to  a)bort  posting the article, e)dit the article again or p)ost the article to the
       specified newsgroup(s).

       Use the DisplayPostHist ('W') command to display  a  history  of  the  articles  you  have
       posted.  The  date  the article was posted, which newsgroups the article was posted to and
       the articles subject line are displayed.

       Use the PageFollowupQuote ('f'), PageFollowup  ('F')  or  PageFollowupQuoteHeaders  ('^W')
       command  to  post  a follow-up article to an already posted article. The PageFollowupQuote
       command  will  copy  the  text  of   the   original   article   into   the   editor.   The
       PageFollowupQuoteHeaders  command  will  copy  the  text  and  all headers of the original
       article into the editor. The editing procedure is the same as when posting an article with
       the Post ('w') command.

       Use  the  PageReplyQuote ('r'), PageReply ('R') or PageReplyQuoteHeaders ('^E') command to
       reply direct through mail to the author of an already posted article.  The  PageReplyQuote
       command   will   copy   the   text   of   the   original  article  into  the  editor.  The
       PageReplyQuoteHeaders command will copy the text and all headers of the  original  article
       into  the  editor.  The  editing procedure is the same as when posting an article with the
       Post ('w') command. After saving and exiting the editor you are asked if you wish to abort
       sending the article via PostAbort ('a'), edit the article again via PostEdit ('e') or send
       the article to the author via PostSend ('s').

   CUSTOMIZING THE ARTICLE QUOTE STRING
       When posting a followup to an article or replying direct to the author of an  article  via
       email  the text of the article can be quoted. The beginning of the quoted text can contain
       information about the quoted article (e.g., Name and the Message-ID of  the  article).  To
       allow  for  different  situations  certain information from the article can be used in the
       quoted string. The following variables are  expanded  if  found  in  the  tinrc  variables
       mail_quote_format, news_quote_format or xpost_quote_format:
              %A  Address (Email)
              %D  Date (uses date_format)
              %F  Full address (%N <%A>)
              %G  Groupname
              %M  Message-ID
              %N  Fullname of author
              %C  Firstname of author
              %I  Initials of author
       e.g.,
              mail_quote_format=On %D in %G you wrote:
              news_quote_format=In %M, %F wrote:
       would expand to:

       The  quoted  text  section  of  an  article  is  marked by a preceding quote string at the
       beginning of each quoted line. The default quote string is set to '>_'. The default can be
       changed  by  setting the tinrc variable quote_chars to ones own preference. (Note that '_'
       underline is used to represent a space).

   MAILING PIPING PRINTING REPOSTING AND SAVING ARTICLES
       The command interface to GroupMail, PageMail, PostMail or ThreadMail  ('m'),  Pipe  ('|'),
       Print  ('o'),  PageRepost  or GroupRepost ('x') and GroupSave, PageSave or ThreadSave ('s'
       and GroupAutoSave, PageAutoSave or ThreadAutoSave 'S') articles is the same  for  ease  of
       use.

       Auto-saving  with  *AutoSave ('S') is a special case and operates only on marked articles.
       They will processed without any further prompting according to the default save parameters
       defined in tinrc or by any attributes set for the current group.

       Otherwise,  the  initial  prompt  will ask you to select which article, thread, hot (auto-
       selected), regular expression pattern, tagged articles you wish to mail, pipe etc.

       Tagged articles must have already been tagged  with  a  *Tag  ('t')  command.  All  tagged
       articles can be untagged by a *Untag ('U') untag command.

       If  a  regular  expression  pattern is selected you are asked to enter a pattern (e.g., to
       match all articles subject lines containing 'net News' you enter "net News"). Any articles
       that  match  the entered expression will be mailed, piped etc. See also the wildcard tinrc
       variable for advanced pattern matching options.

       Various expansion characters are recognized when entering the directory and file  to  save
       to.  Environment  variables (prefixed with '$') and user home directories (prefixed by '~'
       or '~username') can be specified.  Environment  variables  can  themselves  contain  other
       special characters.

       To save articles to a mailbox enter '=<mailbox name>' when asked for the save filename. If
       you enter just '=' then articles will be saved to a mailbox with the name of  the  current
       newsgroup (eg, alt.sources).  See maildir.

       To  save  in savedir/<news.group.name>/<filename> format enter '+<filename>'.  Environment
       variables are allowed within a filename (e.g., $SOURCES/dir/filename). See savedir.

       When saving articles you can specify whether the saved files should be post  processed.  A
       default process type can be set via post_process_type.

   AUTOMATIC MAILING AND SAVING NEW NEWS
       tin  allows  new/unread  news  articles  to  be mailed (''-M'' and ''-N'' option) or saved
       (''-S'' option) in batch mode for later reading. Useful when  going  on  holiday  and  you
       don't  want  to  return  and find that expire has removed a whole load of unread articles.
       Best to run via cron(8) everyday while away, after which you will be mailed  a  report  of
       which  articles  were  mailed/saved from which newsgroups and the total number of articles
       mailed/saved. Articles are saved in a private news structure under your savedir  directory
       (default  is ${TIN_HOMEDIR:-"$HOME"}/News).  Be careful of using this option if you read a
       lot of groups because you could overflow your file system.

       When using ''-S'' together with a given directory to save to  (''-s''  option),  the  same
       directory must be specified when reading the articles by ''-R''.

       If  you only want to save some of your groups use the batch_save tinrc variable. Set to ON
       or OFF in tinrc to enable/disable saving  of  all  groups  and  then  use  the  batch_save
       attribute  to  fine  tune which groups you want to have saved. For example, if you want to
       save most of your groups, then set batch_save to ON in tinrc and selectively turn off  the
       ones you don't want using attributes.

       tin -M iain -c -f newsrc.mail
                           (mail  any unread articles in newsgroups specified in file newsrc.mail
                           to the local user iain and mark them as read)

       tin -S -c -f newsrc.save
                           (save any unread articles in newsgroups specified in file  newsrc.save
                           and mark them as read)

       tin -R              (read any articles saved by tin -S)

   RANGES
       A  range  is  simply  a  group  of  items marked using the SetRange ('#') key. Certain tin
       commands will operate on a range if one exists rather than just the current item. A  range
       is an expression of the form <min>–<max>, e.g. 10–15 will highlight items 10 through 15 on
       the current screen. Other than absolute numeric positions, '.' can be used in place of the
       current  cursor  position  and  '$'  can  be  used  to  mean the highest number available.
       Currently  the  only  commands  that  understand  ranges   are   GroupMarkThdRead   ('K'),
       MarkArtUnread ('z') and MarkThdUnread ('Z').

   NEWSGROUP LISTS & WILDCARDS
       Several  places  in  tin allow you to specify a list of newsgroups. These include command-
       line groups, (un)subscribe groups, the AUTO[UN]SUBSCRIBE mechanism. The scope=  attributes
       file  tag  and  the  filter  file group= tag also use the same syntax. tin interprets this
       variable similarly to rn(1).  It contains a list of  patterns,  separated  by  commas  and
       possibly  prefixed  with exclamation points. An exclamation point negates the meaning of a
       match on this pattern, and can be used to cancel certain matches. Some examples:

       alt.config,news.*,!news.test

       Matches alt.config and everything in the 'news' hierarchy except news.test

       See the explanation for the $AUTOSUBSCRIBE variables for further examples.

   SIGNATURES
       tin  will  recognize  a  signature   in   either   ${TIN_HOMEDIR:-"$HOME"}/.signature   or
       ${TIN_HOMEDIR:-"$HOME"}/.Sig.   If  ${TIN_HOMEDIR:-"$HOME"}/.signature  exists,  then  the
       signature will be  pulled  into  the  editor  for  mail  commands  only.  A  signature  in
       ${TIN_HOMEDIR:-"$HOME"}/.signature will not be pulled into the editor for posting commands
       since inews(1) will append the signature itself.

       A signature in ${TIN_HOMEDIR:-"$HOME"}/.Sig will  be  pulled  into  the  editor  for  both
       posting and mailing commands.

       The following is an example of a .Sig file:
              NAMES  Joe Bar <joe@example.org>
              SNAIL  Musterweg 12, 99999 Notreal, Germany

       tin  also  has the capability to generate random signatures on a per newsgroup basis if so
       desired. The way to accomplish this is to specify  the  default  signature  or  the  group
       attribute  sigfile  as a directory. If for example the sigfile path is /usr/iain/.sigs and
       .sigs is a directory then tin will select a random signature from any file that is in  the
       directory  .sigs  (note:  one  signature  per  numbered file). A random signature can also
       consist of a fixed part signature that can contain your name, address etc. followed by the
       random sig. The fixed part of the random sig is read from the file $HOME/.sigfixed.

   CUSTOMIZING THE SCREEN FORMAT
       The  look  of  the Selection, Group and Thread level can be customized via format strings.
       These format strings define the content and the position of each element  on  the  screen.
       Variables  are used within the format strings as placeholders. The following variables are
       available:

          %D    date
          %F    from, name and/or address
          %G    newsgroup name
          %I    initials
          %L    line count
          %M    message-id
          %R    number of responses in thread
          %S    score
          %T    thread tree
          %U    unread count
          %d    newsgroup description
          %f    newsgroup flag
          %m    article marks
          %n    current group/thread/article number
          %s    subject
          %%    %

       Not all variables can be used in each level. The following table provides an overview:

              select_format group_format thread_format
          %D                      X            X
          %F                      X            X
          %G        X
          %I                      X            X
          %L                      X            X
          %M                      X            X
          %R                      X
          %S                      X            X
          %T                                   X
          %U        X
          %d        X
          %f        X
          %m                      X            X
          %n        X             X            X
          %s                      X
          %%        X             X            X

       Defaults for the format strings:

          select_format: "%f %n %U  %G  %d"
          group_format:  "%n %m %R %L  %s  %F"
          thread_format: "%n %m  [%L]  %T  %F"

       show_description  controls  whether  the  newsgroup  description  is  shown  or  not.  The
       description can also be toggled with SelectToggleDescriptions ('d').

       The   information   displayed   with   '%F'   depends   on   the   value  of  show_author.
       GroupToggleSubjDisplay resp.  ThreadToggleSubjDisplay ('d') switches through all available
       options.

       For  date representation '%D' uses date_format. It is possible to specify a different date
       format in round brackets (e.g. '%(%d %b %y %H:%M)D'). See date_format for more details.

       The length of each item (except '%%') can be defined with a positive number after the '%'.
       The following example displays the score in the thread level 10 characters wide: '%10S'.

       If  the  newsgroup name is displayed together with the newsgroup description, the width of
       the newsgroup name can be controlled via an optional comma separated  second  value  (e.g.
       '%60,20G').  It  is  valid to omit the first value (e.g. ('%,20G')). If no second value is
       given, tin uses a default value of 32.

       Some variables do have a default width which  may  lead  to  truncation.   Truncation  for
       variables which contain only numbers happens by dividing the value with a sufficient power
       of ten and adding a SI suffix to the result, that is the variable holds a value  of  54321
       and  the  width  for  the variable is 4 the result will be "54 k". If that's undesired you
       have to specify a larger width manually, e.g. '%6n'. Here is an overview of the defaults:

          Variable  width
          %I         3
          %L         4
          %M        10
          %R         3
          %S         6
          %U         5
          %n         4

       If no length is given for '%D', the length is determined by the format string for the date
       and  the  date  of  the current day. If the date format string contains weekdays or months
       names it may happen that the date is longer than determined in the  first  pass.  In  this
       case, the date is truncated before display. This occurs, for example, if the current month
       is May and the article to which the date is displayed was  posted  in  December.  In  such
       cases  it  might useful to determine the maximum length manually and specify the length in
       the format string.

       In case the format string contains '%G' and '%d' and no length are given,  tin  determines
       the  longest  newsgroup  name and uses this length for '%G'. The remaining space will used
       for '%d'.

       When the format string contains the specifier '%F' and '%s' resp. '%T' and no  length  are
       given,  '%F'  will  use  one third and '%s' resp. '%T' will use two third of the available
       space.

       In addition, a minimum screen width can be defined for each item (except  '%%').  In  this
       case,  the item will only be displayed when the screen is wider than specified. This comes
       in handy to not overload a small screen but have maximum information on  a  large  screen.
       The  minimum  screen width has to be specified by a positive number preceded by an '>'. In
       the following example tin will display the score only if the  screen  is  wider  than  100
       characters: '%>100S'.

       If  both  the  length  and  the  minimum screen width should be specified for an item, the
       length must be the first parameter and the minimum screen width must be  the  second  one.
       The following example displays the score with a length of 10 characters only if the screen
       is wider than 100 characters: '%10>100S'.

   TIPS AND TRICKS
       tin can be pretty much be navigated by using the four cursor keys.   The  left  arrow  key
       goes  up  a  level, the right arrow key goes down a level, the up arrow key goes up a line
       and the down arrow key goes down a line.

       The following newsgroups provide useful information concerning news software:
           —news.software.readers (info. about news user agents tin, rn, nn, slrn etc.)
           —news.software.nntp (info. about NNTP)
           —news.answers (Frequently Asked Questions (FAQ) about many different themes)

       Many prompts within tin offer a default choice  that  the  cursor  is  positioned  on.  By
       pressing  '<CR>'  the  default  value  is  taken.  Most prompts can be aborted by pressing
       '<ESC>'.

       When tin is run in a xterm(1x) it will resize itself each time the xterm(1x) is resized.

       tin will reread  the  ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file  at  set
       intervals (reread_active_file_secs) to show any newly arrived news.

       If  you  find  large  number  of  new  newsgroups  cluttering  up  your  screen,  pressing
       SelectToggleReadDisplay ('r') will make them go away.

   XTERM BUTTONS
       If the environment variable $TERM is set to xterm(1x), then button pressing can be used to
       select  groups  and  articles.  In this discussion, the buttons are assumed to be assigned
       conventionally (i.e., Button1 is the left button).

       In general (i.e., for the group, thread and article menus),

       Button1 (left)
                 enters next (lower) level if you click on an article, otherwise pages down.

       Button2 (center)
                 returns to the previous (upper) level if you  click  on  an  article,  otherwise
                 pages up.

       Button3 (right)
                 positions  on  the  article  line  under  mouse  cursor, or pages down if you've
                 clicked outside the list of articles.

       In the group selection menu, if the mouse is pointing at a group then:

       left button
                 moves to and selects the group pointed at, just like SelectReadGrp ('<CR>').

       center button
                 quits the program, just like Quit ('q').

       right button
                 moves to the group pointed at.

       In the article menu, if the mouse is pointing at an article (or thread) then:

       left button
                 reads the article pointed at,  just  like  GroupReadBasenote  ('<CR>'),  or  the
                 thread, just like GroupListThd ('l').

       center button
                 exits  the  menu, catching up on the group if you have group_catchup_on_exit set
                 in your configuration, just like Quit ('q').

       right button
                 moves to the article (or thread) pointed at.

       In the thread menu, if the mouse is pointing at an article then:

       left button
                 reads article pointed at, just like ThreadReadArt ('<CR>').

       center button
                 exits the menu, catching up on the thread if you have thread_catchup_on_exit set
                 in your configuration, just like Quit ('q').

       right button
                 moves to the article pointed at.

       In other menus and areas button pressing reverts back to usual cut and paste of xterm(1x),
       but after one click of any button.

   INDEX FILES
       If  your  news  server  supports  NOV  index  files  (see  newsoverview(5),  most   modern
       installations  will)  and you have a fast connection to your news server then this section
       can be ignored.

       If your news server doesn't support NOV index files or you have a very slow connection  to
       your  news  server then tin can cache the index for each newsgroup if cache_overview_files
       is set to ON.  Note that this cache can use up large amounts of disk space if you  read  a
       lot of groups and/or high traffic groups.

       Each    user    creates/updates   his/her   own   index   files   that   are   stored   in
       ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news/. If you are reading  via  NNTP
       then  the  news  server  name  will  be appended to keep the indexes for different servers
       separate. If you are reading off the local spool and local overview  files  already  exist
       then  turning  on  caching will have no effect. Likewise unless you see significant delays
       entering a group when reading via NNTP then turning on caching  will  have  little  or  no
       effect.

       Entering a group the first time tends to be slow because the index file must be built from
       scratch. To alleviate the slowness start tin to create all index files for the groups  you
       subscribe  to with tin -u -v and go for a coffee. Subsequent readings of a group will only
       need to do incremental updating of the index file and will be  much  faster  as  only  new
       articles will need to be cached.

       As  indexing  might take some time you may want to run tin form the system batcher cron(8)
       with the ''-u'' option:

              30 6 * * * /usr/local/bin/tin -u

       If you are low on local disk space you should consider to manually purge cached  data  for
       groups you are not reading anymore with something like:

              find ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news* \
              -type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

ENVIRONMENT

       TINRC  Define this variable if you want to specify command-line options that tin should be
              started with to save typing them each time it  is  started.  The  contents  of  the
              environment  variable  are added to the front of the command-line options before it
              is parsed therefore allowing an option specified on the  command-line  to  override
              the same option specified in the environment.

       TIN_HOMEDIR
              Define  this variable if you do not want the .tin directory in $HOME/. E.g., if you
              want all tin's private files in /tmp/.tin you would set $TIN_HOMEDIR to /tmp.

       TIN_INDEX_NEWSDIR
              Define  this   variable   if   you   do   not   want   the   .news   directory   in
              ${TIN_HOMEDIR:-"$HOME"}/.tin/.  E.g.,  if  you  want  all tin's news index files in
              /tmp/.news you would set $TIN_INDEX_NEWSDIR to /tmp.

       TIN_INDEX_MAILDIR
              Define  this   variable   if   you   do   not   want   the   .mail   directory   in
              ${TIN_HOMEDIR:-"$HOME"}/.tin/.  E.g.,  if  you  want  all tin's mail index files in
              /tmp/.mail you would set $TIN_INDEX_MAILDIR to /tmp.

       TIN_INDEX_SAVEDIR
              Define  this   variable   if   you   do   not   want   the   .save   directory   in
              ${TIN_HOMEDIR:-"$HOME"}/.tin/.  E.g.,  if  you  want  all tin's save index files in
              /tmp/.save you would set $TIN_INDEX_SAVEDIR to /tmp.

       TIN_LIBDIR
              Define this variable if you want to override the NEWSLIBDIR path that was  compiled
              into  the  tin  binary,  default  is /usr/lib/news.  If tin is running in NNTP mode
              setting this variable has no effect.

       TIN_SPOOLDIR
              Define this variable if you want to override the SPOOLDIR path  that  was  compiled
              into  the  tin  binary, default is /var/spool/news.  If tin is running in NNTP mode
              setting this variable has no effect.

       TIN_NOVROOTDIR
              Define this variable if you want to override the NOVROOTDIR path that was  compiled
              into  the  tin  binary,  default is SPOOLDIR (see above). If tin is running in NNTP
              mode setting this variable has no effect.

       TIN_NOVFILENAME
              Define this variable if you want to override the OVERVIEW_FILE  filename  that  was
              compiled  into the tin binary, default is .overview. If tin is running in NNTP mode
              setting this variable has no effect.

       TIN_ACTIVEFILE
              Define this variable if you want to override the NEWSLIBDIR/active  path  that  was
              compiled  into the tin binary. If tin is running in NNTP mode setting this variable
              has no effect. If $TIN_LIBDIR is set it is prepended to $TIN_ACTIVEFILE.

       NNTPSERVER
              The default NNTP server to remotely read news from. This variable only needs to  be
              set  if  the  ''-r'' command-line option is specified and the file /etc/news/server
              does not exist. The ''-g'' command line option overrides $NNTPSERVER.

       NNTPPORT
              The NNTP TCP-port to read news from. This variable only needs to be set if the TCP-
              port is not 119 (the default).  The ''-p'' command-line option overrides $NNTPPORT.

       DISTRIBUTION
              Set  the  article  header  field  ''Distribution:'' to the contents of the variable
              instead of the system default.

       ISO2ASC
              Set the ISO to ASCII charset decoding table character to use in decoding an article
              text. Values can range from -1 to 6.

            -1     no conversion

            0      universal table for many languages

            1      single-spacing universal table

            2      table for Danish, Dutch, German, Norwegian and Swedish

            3      table for Danish, Finnish, Norwegian and Swedish using the appropriate ISO 646
                   variant

            4      table with RFC1345 codes in brackets

            5      table for printers that allow overstriking with backspace

            6      table for IBM PC character set (code page 437)

       ORGANIZATION
              Set the article header field ''Organization:'' to  the  contents  of  the  variable
              instead  of  the  system default. If reading news on an Apollo DomainOS machine the
              environment variable $NEWSORG has to be used instead of $ORGANIZATION.

       NEWSORG (DomainOS)
              DomainOS specific, same as $ORGANIZATION on other OSs (see above).

       REPLYTO
              Set the article header field ''Reply-To:'' to the return address specified  by  the
              variable. This is useful if you wish to receive replies at a different address.

       NAME   Overrides  the  full  name  given  in  the  gecos-field  in  /etc/passwd,  see also
              mail_address.

       REALNAME
              Same as $NAME.

       HOME   Pathname of the user's home directory. See environ(5) for more info.

       MAILER This variable has precedence over the default mailer that is used  in  all  mailing
              operations within tin.

       MAIL   Full path to the user's mailbox.

       VISUAL This  variable has precedence over the default editor (i.e., vi(1)) that is used in
              all editing operations within  tin  (e.g.,  posting,  replying,  follow-ups,  ...).
              Evaluation order is ${VISUAL:-"${EDITOR:-vi}"}. See environ(5) for more info.

       EDITOR If  $VISUAL  is  unset,  then  this  variable is looked up for a default editor. If
              $EDITOR and $VISUAL are both unset, tin  uses  the  systems  default  editor  (i.e.
              vi(1)) on UNIX-systems). See environ(5) for more info.

       AUTOSUBSCRIBE
              A  new group is checked against the list of patterns; if it matches, tin subscribes
              the user to the group without further query.  See the section  "NEWSGROUP  LISTS  &
              WILDCARDS" for an explanation of the valid syntax. For example, setting

              AUTOSUBSCRIBE=comp.os.unix.*,talk.*,!talk.politics.*

              will  automatically  subscribe  the  user  to  all  new  groups in the comp.os.unix
              hierarchy, and all talk groups other  than  talk.politics  groups  (which  will  be
              queried  for  as  usual).  Of  course this does not work if tin is started with the
              ''-X'' command-line switch.

       AUTOUNSUBSCRIBE
              Is handled like the $AUTOSUBSCRIBE variable,  but  groups  matching  the  list  are
              unsubscribed from without further query. For example, setting

              AUTOUNSUBSCRIBE=alt.flame.*,u*,!uk.*

              will  automatically  unsubscribe  the  user  from  all new alt.flame groups and all
              groups starting with u (university groups) other than  UK  groups  (which  will  be
              queried for as usual).

       TMPDIR A pathname of a directory made available for tin to create temporary files.

       MAILCAPS
              This variable can be used to override the default path search for mailcap(5) files.
              See also tin(5).

       NOMETAMAIL
              Set this variable to  disable  the  use  of  metamail(1)  or  a  replacement  (e.g.
              metamutt).

       MM_CHARSET
              MIME character set used if not configured via the tinrc variable mm_charset.

       ISPELL Set this variable to point to ispell(1) or a replacement and its cmd-line options.

       PGPOPTS
              Define  any  additional  options  that  you  wish  to pass to your pgp(1) or gpg(1)
              program.

       PGPPATH
              Override the name of the pgp(1) directory in $HOME that holds your keys etc..

       GNUPGHOME
              Override the name of the gpg(1) directory in $HOME that holds your keys etc..

       LC_CTYPE
              This variable determines the locale(5) category for character  handling  functions.
              Usually  it  determines  the  character  classes  for  pattern  matching  character
              classification and case conversion. Currently this  is  not  true  for  tin  (which
              temporary  unsets  $LC_CTYPE  right  before  any match is done to avoid confusion).
              It's value should be of  the  form  language[_territory][.codeset][@modifier].  See
              environ(5) for more information.

       LC_MESSAGES
              Formats  of  informative  and  diagnostic messages and interactive responses.  It's
              value  should  be  of  the  form   language[_territory][.codeset][@modifier].   See
              locale(5) and environ(5) for more information.

       LC_TIME
              Date    and    time    formats.    It's    value    should    be    of   the   form
              language[_territory][.codeset][@modifier]. See locale(5) and  environ(5)  for  more
              information.

       LC_ALL This  variable  overrides  the  value  of  the  $LANG  variable  and any other $LC_
              variable. It's value should be  of  the  form  language[_territory][.codeset].  See
              locale(5) and environ(5) for more information.

       LANG   This  variable  determines the locale(5) category for any category not specifically
              selected with a variable starting with $LC_. It's  value  should  be  of  the  form
              language[_territory][.codeset]. See environ(5) for more information.

       LANGUAGE
              This  variable  defines a priority list for translations. Whenever a translation is
              not available in the language selected via $LC_ALL or $LANG the next language  from
              the  list  is tried. It's value should be of the form language:language[:language].
              See environ(5) for more information.

       COLUMNS
              A decimal integer > 0 used  to  indicate  the  user's  preferred  width  in  column
              positions for the terminal screen or window. If this variable is unset or null, the
              implementation determines the number of columns, appropriate for  the  terminal  or
              window.  When $COLUMNS is set, any terminal-width information implied by $TERM will
              be overridden. Users and portable applications should not set $COLUMNS unless  they
              wish  to override the system selection and produce output unrelated to the terminal
              characteristics.

       LINES  A decimal integer > 0 used to indicate the user's preferred number of  lines  on  a
              page  or  the  vertical  screen  or  window size in lines. A line in this case is a
              vertical measure large enough to hold the tallest character in  the  character  set
              being  displayed.  If this variable is unset or null, the implementation determines
              the number of lines, appropriate for the terminal or window. When  $LINES  is  set,
              any  terminal-height  information  implied  by  $TERM will be overridden. Users and
              portable applications should not set $LINES unless they wish to override the system
              selection.

       TERM   The  type  of terminal in use. This is used when looking up termcap sequences.  See
              environ(5) for more information.

       DISPLAY
              Display name, pointing to the X server; required for xface.

       WINDOWID
              Used for determining terminal's X window id; required for xface. Should be  set  by
              the terminal emulator.

       SHELL  The pathname of the user's login shell. Used to set default_shell_command.

       XDG_RUNTIME_DIR
              The pathname of the user's dir to put non-essential run time files into.

SIGNALS

       tin handles a couple of signals:

       SIGHUP Terminate gracefully.

       SIGTERM
              Terminate gracefully.

       SIGUSR1
              Terminate gracefully but do not restore terminal (tty).

       SIGUSR2
              Write out ${TIN_HOMEDIR:-"$HOME"}/.newsrc-file.

SECURITY

       If  tin is started in debug mode (''-D n'') it will create world readable files in $TMPDIR
       which may contain the users NNTP  password  in  cleartext.  On  multiuser-systems  $TMPDIR
       should be set to a safe location before starting tin in debug mode (e.g.  TMPDIR=$HOME tin
       -D 1).

CONFORMING TO

       tin does conform to the Base Definitions volume  of  IEEE  Std  1003.1-2008,  Section  12,
       Utility Conventions (Utility Argument Syntax, Utility Syntax Guidelines).

BUGS

       CNews  NNTPd,  noffle(1)  (<= V1.0-pre5) and NewsCache (<= V1.1.91) can't handle pipelined
       GROUP commands. If you  run  into  trouble  with  any  of  the  mentioned  servers  define
       DISABLE_PIPELINING in include/autoconf.h and recompile.

HISTORY

       tin  is  based  on the tass(1) newsreader that was developed by Rich Skrenta and posted to
       alt.sources in March 1991; its first version was released on August  23rd  1991.   tass(1)
       itself  was  heavily influenced by notesfiles a public domain UNIX version of PLATO Notes,
       developed at the University of Illinois by Ray Essick and  Rob  Kolstad  in  1982.  For  a
       version overview see
       <http://www.tin.org/history.html>.
