VERSION

       This man page documents lftp version 4.3.3.

DESCRIPTION

       lftp is a file transfer program that allows sophisticated ftp, http and
       other connections to other hosts. If site is specified then  lftp  will
       connect  to that site otherwise a connection has to be established with
       the open command.

       lftp can handle several file access methods - ftp, ftps,  http,  https,
       hftp,  fish, sftp and file (https and ftps are only available when lftp
       is compiled with GNU TLS or  OpenSSL  library).  You  can  specify  the
       method    to    use    in    `open    URL'    command,    e.g.    `open
       http://www.us.kernel.org/pub/linux'.   hftp   is    ftp-over-http-proxy
       protocol.  It  can be used automatically instead of ftp if ftp:proxy is
       set to `http://proxy[:port]'. Fish is a protocol working  over  an  ssh
       connection to a unix account. SFtp is a protocol implemented in ssh2 as
       sftp subsystem.

       Besides FTP-like protocols, lftp has support for BitTorrent protocol as
       `torrent' command. Seeding is also supported.

       Every  operation  in  lftp  is reliable, that is any not fatal error is
       ignored and the operation is repeated. So  if  downloading  breaks,  it
       will be restarted from the point automatically. Even if ftp server does
       not support REST command, lftp will try to retrieve the file  from  the
       very beginning until the file is transferred completely.

       lftp  has  shell-like  command  syntax  allowing  you to launch several
       commands in parallel in background (&). It is also  possible  to  group
       commands  within () and execute them in background. All background jobs
       are executed in the same single process. You can bring a foreground job
       to background with ^Z (c-z) and back with command `wait' (or `fg' which
       is alias to `wait'). To list running jobs,  use  command  `jobs'.  Some
       commands  allow  redirecting their output (cat, ls, ...) to file or via
       pipe to external command. Commands can be executed conditionally  based
       on termination status of previous command (&&, ||).

       If  you  exit  lftp when some jobs are not finished yet, lftp will move
       itself to nohup mode in background. The same happens when  you  have  a
       real modem hangup or when you close an xterm.

       lftp has built-in mirror which can download or update a whole directory
       tree. There is also reverse mirror (mirror -R) which uploads or updates
       a  directory  tree  on  server. Mirror can also synchronize directories
       between two remote servers, using FXP if available.

       There is command `at' to launch a job  at  specified  time  in  current
       context, command `queue' to queue commands for sequential execution for
       current server, and much more.

       On  startup,  lftp  executes  /etc/lftp.conf  and  then  ~/.lftprc  and
       ~/.lftp/rc. You can place aliases and `set' commands there. Some people
       prefer to see full protocol debug, use `debug' to turn  the  debug  on.
       Use `debug 3' to see only greeting messages and error messages.

       lftp  has  a  number of settable variables. You can use `set -a' to see
       all variables and their values or `set -d' to  see  list  of  defaults.
       Variable  names can be abbreviated and prefix can be omitted unless the
       rest becomes ambiguous.

       If lftp was compiled with OpenSSL (configure --with-openssl),  then  it
       includes  software  developed  by  the  OpenSSL  Project for use in the
       OpenSSL Toolkit. (http://www.openssl.org/)

   Commands
       ! shell command

       Launch shell or shell command.

            !ls

       To do a directory listing of the local host.

       alias  [name [value]]

       Define or undefine alias name.  If  value  is  omitted,  the  alias  is
       undefined,  else  it takes the value value. If no argument is given the
       current aliases are listed.

            alias dir ls -lF
            alias less zmore

       at time [ -- command ]

       Wait until the given time and execute  given  (optional)  command.  See
       also at(1).

       attach  [PID]

       Attach the terminal to specified backgrounded lftp process.

       bookmark  [subcommand]

       The bookmark command controls bookmarks.

            add <name> [<loc>]   add   current  place  or  given  location  to
                                 bookmarks and bind to given name
            del <name>           remove bookmark with name
            edit                 start editor on bookmarks file
            import <type>        import foreign bookmarks
            list                 list bookmarks (default)

       cache  [subcommand]

       The  cache  command  controls  local  memory  cache.    The   following
       subcommands are recognized:

            stat        print cache status (default)
            on|off      turn on/off caching
            flush       flush cache
            size lim    set memory limit, -1 means unlimited

            expire Nx   set  cache  expiration time to N seconds (x=s) minutes
                        (x=m) hours (x=h) or days (x=d)

       cat files

       cat outputs the remote file(s) to stdout.  (See  also  more,  zcat  and
       zmore)

       cd rdir

       Change  current  remote  directory.   The  previous remote directory is
       stored as `-'. You can do `cd -' to change  the  directory  back.   The
       previous  directory for each site is also stored on disk, so you can do
       `open site; cd -' even after lftp restart.

       chmod mode files

       Change permission mask on remote files.  The  mode  must  be  an  octal
       number.

       close [-a]

       Close  idle  connections.  By default only with the current server, use
       -a to close all idle connections.

       cls [OPTS] files...

       `cls'  tries  to  retrieve  information  about   specified   files   or
       directories  and  outputs  the information according to format options.
       The difference between `ls' and `cls' is that `ls' requests the  server
       to  format  file listing, and `cls' formats it itself, after retrieving
       all the needed information.  See `help cls' for options.

       command cmd args...

       execute given command ignoring aliases.

       debug [-o file] level|off

       Switch debugging to level or turn it off.  Use -o to redirect the debug
       output to a file.

       echo [-n] string

       guess what it does.

       eval [-f format ] args...

       without  -f  it  just  executes  given arguments as a command. With -f,
       arguments are transformed into a new command. The  format  can  contain
       plain  text  and  placeholders  $0...$9  and  $@,  corresponding to the
       arguments.

       exit [bg] [top] [kill] [code]

       exit will exit from lftp or move to  background  if  there  are  active
       jobs. If no job is active, code is passed to operating system as lftp's
       termination status. If code is omitted, the exit code of  last  command
       is used.

       `exit  bg'  forces  moving  to  background  when cmd:move-background is
       false.  `exit top' makes  top  level  `shell'  (internal  lftp  command
       executor)  terminate.   `exit  kill'  kills  all  numbered  jobs before
       exiting. The options can be combined, e.g.  `at 08:00 -- exit top  kill
       &' kills all jobs and makes lftp exit at specified time.

       fg

       Alias for `wait'.

       find  [directory]

       List files in the directory (current directory by default) recursively.
       This can help with servers lacking ls  -R  support.  You  can  redirect
       output of this command.

       ftpcopy

       Obsolete. Use one of the following instead:
            get ftp://... -o ftp://...
            get -O ftp://... file1 file2...
            put ftp://...
            mput ftp://.../*
            mget -O ftp://... ftp://.../*
       or  other  combinations  to  get FXP transfer (directly between two ftp
       servers).  lftp would fallback  to  plain  copy  (via  client)  if  FXP
       transfer cannot be initiated or ftp:use-fxp is false.

       get [-E] [-a] [-c] [-e] [-O base] rfile [-o lfile] ...

       Retrieve  the  remote  file rfile and store it as the local file lfile.
       If -o is omitted, the file is stored to local file named as  base  name
       of  rfile.  You can get multiple files by specifying multiple instances
       of rfile (and -o lfile). Does not expand wildcards, use mget for that.

            -c          continue, reget
            -E          delete source files after successful transfer
            -e          delete target file before the transfer
            -a          use ascii mode (binary is the default)
            -O <base>   specifies base directory or URL where files should  be
                        placed

       Examples:
            get README
            get README -o debian.README
            get README README.mirrors
            get README -o debian.README README.mirrors -o debian.mirrors
            get README -o ftp://some.host.org/debian.README
            get README -o ftp://some.host.org/debian-dir/   (end slash is important)

       get1 [OPTS] rfile

       Transfer a single file. Options:

            -o <lfile>                  destination   file   name  (default  -
                                        basename of rfile)
            -c                          continue, reget
            -E                          delete source files  after  successful
                                        transfer
            -a                          use ascii mode (binary is the default)
            --source-region=<from-to>   transfer  specified  region  of source
                                        file
            --target-position=<pos>     position in target file to write  data
                                        at

       glob [-d] [-a] [-f] command patterns

       Glob  given patterns containing metacharacters and pass result to given
       command.  E.g. ``glob echo *''.

            -f   plain files (default)

            -d   directories
            -a   all types

       help [cmd]

       Print help for cmd or if no cmd was specified print a list of available
       commands.

       jobs [-v]

       List running jobs. -v means verbose, several -v can be specified.

       kill all|job_no

       Delete specified job with job_no or all jobs.  (For job_no see jobs)

       lcd ldir

       Change  current  local  directory ldir. The previous local directory is
       stored as `-'. You can do `lcd -' to change the directory back.

       ln [-s] existing-file new-link

       Make a hard/symbolic link to  an  existing  file.   Option  -s  selects
       creation of a symbolic link.

       local command

       Run  specified  command with local directory file:// session instead of
       remote session. Examples:
            local pwd
            local ls
            local mirror /dir1 /dir2

       lpwd

       Print current working directory on local machine.

       ls params

       List remote files. You can redirect output of this command to  file  or
       via  pipe to external command.  By default, ls output is cached, to see
       new listing use rels or cache flush.

       mget [-c] [-d] [-a] [-E] [-O base] files

       Gets selected files with expanded wildcards.

            -c          continue, reget.
            -d          create directories the same as file names and get  the
                        files into them instead of current directory.
            -E          delete source files after successful transfer
            -a          use ascii mode (binary is the default)
            -O <base>   specifies  base directory or URL where files should be
                        placed

       mirror [OPTS] [source [target]]

       Mirror specified source directory to local target directory. If  target
       directory ends with a slash, the source base name is appended to target
       directory  name.  Source  and/or  target  can  be  URLs   pointing   to
       directories.

            -c,    --continue                continue a mirror job if possible

            -e,    --delete                  delete   files   not  present  at
                                             remote site
                   --delete-first            delete    old    files     before

            -x RX, --exclude RX              exclude matching files
            -I GP, --include-glob GP         include matching files
            -X GP, --exclude-glob GP         exclude matching files
            -v,    --verbose[=level]         verbose operation
                   --log=FILE                write    lftp    commands   being
                                             executed to FILE
                   --script=FILE             write lftp commands to FILE,  but
                                             don't execute them
                   --just-print, --dry-run   same as --script=-
                   --use-cache               use cached directory listings
                   --Remove-source-files     remove  files after transfer (use
                                             with caution)
            -a                               same  as  --allow-chown  --allow-
                                             suid --no-umask

       When  using  -R, the first directory is local and the second is remote.
       If the second directory is omitted, base name  of  first  directory  is
       used.   If  both  directories  are  omitted,  current  local and remote
       directories are used.  If target directory ends with  a  slash  (except
       root directory) then base name of source directory is appended.

       RX is an extended regular expression, just like in egrep(1).

       GP is a glob pattern, e.g. `*.zip'.

       Include  and  exclude options can be specified multiple times. It means
       that a file or directory would be mirrored if it matches an include and
       does  not  match  to  excludes  after  the  include,  or does not match
       anything and the first check is exclude. Directories are matched with a
       slash appended.

       Note  that  symbolic  links  are  not  created when uploading to remote
       server, because ftp protocol cannot do it. To upload  files  the  links
       refer to, use `mirror -RL' command (treat symbolic links as files).

       For  option  --newer-than  you  can  either  specify  a  file  or  time
       specification like that used by  at(1)  command,  e.g.  `now-7days'  or
       `week  ago'. If you specify a file, then modification time of that file
       will be used.

       Verbosity level can be selected  using  --verbose=level  option  or  by
       several -v options, e.g. -vvv. Levels are:
            0 - no output (default)
            1 - print actions
            2 - +print not deleted file names (when -e is not specified)
            3 - +print directory names which are mirrored

       --only-newer  turns off file size comparison and uploads/downloads only
       newer files even if size is  different.  By  default  older  files  are
       transferred and replace newer ones.

       You  can  mirror  between  two  servers  if you specify URLs instead of
       directories.  FXP is  used  automatically  for  transfers  between  ftp
       servers, if possible.

       Some  ftp  servers hide dot-files by default (e.g. .htaccess), and show
       them only when LIST command is used with -a option. In such case try to
       use `set ftp:list-options -a'.

       mkdir [-p] dir(s)

       Make remote directories. If -p is used, make all components of paths.

       module module [ args ]

       Load  given  module  using  dlopen(3) function. If module name does not
       contain a slash, it is searched in directories specified by module:path
       variable.    Arguments   are   passed   to  module_init  function.  See
       README.modules for technical details.

       more files

       Same as `cat files | more'. if PAGER is set,  it  is  used  as  filter.
       (See also cat, zcat and zmore)

       mput [-c] [-d] [-a] [-E] [-O base] files

       Upload  files with wildcard expansion. By default it uses the base name
       of local name as remote one. This can be changed by `-d' option.

            -c          continue, reput
            -d          create directories the same as in file names  and  put
                        the files into them instead of current directory
            -E          delete   source   files   after   successful  transfer
                        (dangerous)
            -a          use ascii mode (binary is the default)
            -O <base>   specifies base directory or URL where files should  be
                        placed

       mrm file(s)

       Same as `glob rm'. Removes specified file(s) with wildcard expansion.

       mv file1 file2

       Rename file1 to file2.

       nlist [args]

       List remote file names

       open [-e cmd] [-u user[,pass]] [-p port] host|url

       Select an ftp server.

       pget [OPTS] rfile [-o lfile]

       Gets  the  specified  file using several connections. This can speed up
       transfer, but loads the net and server heavily impacting  other  users.
       Use only if you really have to transfer the file ASAP.  Options:

            -c           continue  transfer.  Requires  lfile.lftp-pget-status
                         file.
            -n maxconn   set maximum number of connections (default  is  taken
                         from pget:default-n setting)

       put [-E] [-a] [-c] [-O base] lfile [-o rfile]

       Upload  lfile  with  remote name rfile. If -o omitted, the base name of
       lfile is used as remote name. Does not expand wildcards, use  mput  for
       that.

            -o <rfile>   specifies  remote  file  name  (default - basename of
                         lfile)
            -c           continue, reput. It requires permission to  overwrite
                         remote files
            -E           delete   source   files   after  successful  transfer
                         (dangerous)
            -a           use ascii mode (binary is the default)
            -O <base>    specifies base directory or URL where files should be
                         placed

       pwd [-p]

       Print current remote URL. Use `-p' option to show password in the URL.

       queue [-n num ] cmd

       Add  the given command to queue for sequential execution. Each site has
       its own queue. `-n' adds the command  before  the  given  item  in  the
       queue.  Don't try to queue `cd' or `lcd' commands, it may confuse lftp.
       Instead do the cd/lcd before `queue' command, and it will remember  the
       place in which the command is to be done. It is possible to queue up an
       already running job by `queue wait <jobno>', but the job will  continue
       execution even if it is not the first in queue.

       `queue stop' will stop the queue, it will not execute any new commands,
       but already running jobs will continue to run. You can use `queue stop'
       to  create  an  empty  stopped  queue.  `queue start' will resume queue
       execution.  When you exit  lftp,  it  will  start  all  stopped  queues
       automatically.

       `queue'  with  no arguments will either create a stopped queue or print
       queue status.

       queue --delete|-d [index or wildcard expression]

       Delete one or more items from the queue. If no argument is  given,  the
       last entry in the queue is deleted.

       queue --move|-m <index or wildcard expression> [index]

       Move  the given items before the given queue index, or to the end if no
       destination is given.

            -q   Be quiet.
            -v   Be verbose.
            -Q   Output in a format that can be used to re-queue. Useful  with
                 --delete.

       Examples:
            > get file &
            [1] get file
            > queue wait 1
            > queue get another_file
            > cd a_directory
            > queue get yet_another_file

            queue -d 3             Delete the third item in the queue.
            queue -m 6 4           Move the sixth item in the queue before the
                                   fourth.
            queue -m "get*zip" 1   Move all commands matching "get*zip" to the
                                   beginning  of the queue.  (The order of the
                                   items is preserved.)
            queue -d "get*zip"     Delete all commands matching "get*zip".

       quote cmd

       For FTP - send the command uninterpreted. Use with  caution  -  it  can
       lead  to unknown remote state and thus will cause reconnect. You cannot
       be sure that any change of remote state because of  quoted  command  is
       solid - it can be reset by reconnect at any time.

       For   HTTP  -  specific  to  HTTP  action.  Syntax:  ``quote  <command>
       [<args>]''.  Command may be ``set-cookie'' or ``post''.
            open http://www.site.net
            quote set-cookie "variable=value; othervar=othervalue"
            set http:post-content-type application/x-www-form-urlencoded
            quote post /cgi-bin/script.cgi "var=value&othervar=othervalue" > local_file

       For FISH - send the command uninterpreted. This can be used to  execute
       arbitrary  commands on server. The command must not take input or print
       ### at new line beginning. If it does, the protocol will become out  of
       sync.
            open fish://server
            quote find -name \*.zip

       reget rfile [-o lfile]

       Same as `get -c'.

       rels [args]

       Same as `ls', but ignores the cache.

       renlist [args]

       Same as `nlist', but ignores the cache.

       repeat [OPTS] [[-d] delay] [command]

       Repeat  specified  command  with  a  delay between iterations.  Default
       delay is one second, default command is empty.

            -c <count>    maximum number of iterations
            -d <delay>    delay between iterations
            --while-ok    stop when command exits with non-zero code
            --until-ok    stop when command exits with zero code
            --weak        stop when lftp moves to background.

       Examples:
            repeat at tomorrow -- mirror
            repeat 1d mirror

       reput lfile [-o rfile]

       Same as `put -c'.

       rm [-r] [-f] files

       Remove remote files.  Does not expand wildcards, use mrm for  that.  -r
       is  for recursive directory remove. Be careful, if something goes wrong
       you can lose files. -f suppress error messages.

       rmdir dir(s)

       Remove remote directories.

       scache [session]

       List cached sessions or switch to specified session.

       set [var [val]]

       Set variable to given  value.  If  the  value  is  omitted,  unset  the
       variable.  Variable name has format ``name/closure'', where closure can
       specify exact application of the setting. See below  for  details.   If
       set  is  called with no variable then only altered settings are listed.
       It can be changed by options:

            -a   list all settings, including default values
            -d   list only default values, not necessary current ones

       site site_cmd

       Execute site command site_cmd and output the result.  You can  redirect
       its output.

       sleep interval

       Sleep  given time interval and exit. Interval is in seconds by default,
       but can be suffixed with 'm', 'h', 'd'  for  minutes,  hours  and  days
       respectively.  See also at.

       slot [name]

       Select  specified  slot  or  list  all  slots  allocated.  A  slot is a
       connection to a server, somewhat like a virtual console. You can create
       multiple  slots connected to different servers and switch between them.
       You can also use slot:name as a  pseudo-URL  evaluating  to  that  slot
       location.

       Default readline binding allows quick switching between slots named 0-9
       using Meta-0 - Meta-9 keys (often you can use Alt instead of Meta).

       source file
       source -e command

       Execute commands  recorded  in  file  file  or  returned  by  specified
       external command.
            source ~/.lftp/rc
            source -e echo help

       suspend

       Stop  lftp  process. Note that transfers will be also stopped until you
       continue the process with shell's fg or bg commands.

       torrent [OPTS] torrent-files...

       Start BitTorrent process for the given torrent-files, which  can  be  a
       local  file  or  URL.  Local wildcards are expanded. Existing files are
       first validated unless --force-valid option is  given.  Missing  pieces
       are  downloaded.  Files  are  stored  in specified directory or current
       working directory by default.  Seeding  continues  until  ratio  reachs
       torrent:stop-on-ratio setting or time of torrent:seed-max-time outs.

       Options:

            -O <directory>   specifies  base  directory  where files should be
                             placed
            --force-valid    skip file validation (if you are  sure  they  are
                             ok).

       user user [pass]
       user URL [pass]

       Use  specified  info  for remote login. If you specify an URL with user
       name, the entered password will be cached so that future URL references
       can use it.

       version

       Print lftp version.

       wait [jobno]
       wait all

       Wait for specified job to terminate. If jobno is omitted, wait for last
       backgrounded job.

       `wait all' waits for all jobs termination.

       zcat files

       Same as cat, but filter each file through zcat. (See also cat, more and
       zmore)

       zmore files

       Same  as  more,  but filter each file through zcat. (See also cat, zcat
       and more)

   Settings
       On startup, lftp executes ~/.lftprc  and  ~/.lftp/rc.   You  can  place
       aliases  and  `set'  commands  there.  Some  people  prefer to see full
       protocol debug, use `debug' to turn the debug on.

       There is also a system-wide startup file in /etc/lftp.conf.  It can  be
       in different directory, see FILES section.

       lftp has the following settable variables (you can also use `set -a' to
       see all variables and their values):

       bmk:save-passwords (boolean)
              save plain text passwords in ~/.lftp/bookmarks on `bookmark add'
              command.  Off by default.

       cmd:at-exit (string)
              the commands in string are executed before lftp exits.

       cmd:csh-history (boolean)
              enables csh-like history expansion.

       cmd:default-protocol (string)
              The  value  is  used  when  `open'  is  used with just host name
              without protocol. Default is `ftp'.

       cmd:fail-exit (boolean)
              if true, exit when an unconditional (without || and && at begin)
              command fails.

       cmd:interactive (boolean)
              when true, lftp acts interactively, handles terminal signals and
              outputs some extra messages. Default depends on  stdin  being  a
              terminal.

       cmd:long-running (seconds)
              time  of  command execution, which is considered as `long' and a
              beep is done before next prompt. 0 means off.

       cmd:ls-default (string)
              default ls argument

       cmd:move-background (boolean)
              when false, lftp refuses to go to background  when  exiting.  To
              force it, use `exit bg'.

       cmd:move-background-detach (boolean)
              when  true  (default),  lftp  detaches  itself  from the control
              terminal when moving to background, it  is  possible  to  attach
              back  using  `attach' command; when false, lftp tricks the shell
              to move lftp to background process group and continues  to  run,
              then  fg  shell command brings lftp back to foreground unless it
              has done all jobs and terminated.

       cmd:prompt (string)
              The prompt.  lftp  recognizes  the  following  backslash-escaped
              special characters that are decoded as follows:
              \@     insert @ if current user is not default
              \a     an ASCII bell character (07)
              \e     an ASCII escape character (033)
              \h     the hostname you are connected to
              \n     newline
              \s     the name of the client (lftp)
              \S     current slot name
              \u     the username of the user you are logged in as
              \U     the     URL     of     the     remote     site     (e.g.,
                     ftp://g437.ub.gu.se/home/james/src/lftp)
              \v     the version of lftp (e.g., 2.0.3)
              \w     the current working directory at the remote site
              \W     the base name of the current  working  directory  at  the
                     remote site
              \nnn   the character corresponding to the octal number nnn
              \\     a backslash
              \?     skips next character if previous substitution was empty.
              \[     begin  a sequence of non-printing characters, which could
                     be used to embed a terminal  control  sequence  into  the
                     prompt
              \]     end a sequence of non-printing characters

       cmd:parallel (number)
              Number  of  jobs  run  in  parallel in non-interactive mode. For
              example, this may be useful  for  scripts  with  multiple  `get'
              commands.  Note  that  setting  this  to  a value greater than 1
              changes conditional  execution  behaviour,  basically  makes  it
              inconsistent.

       cmd:queue-parallel (number)
              Number of jobs run in parallel in a queue.

       cmd:save-cwd-history (boolean)
              when   true,   lftp   saves   last   CWD   of   each   site   to
              ~/.lftp/cwd_history, allowing to do ``cd -'' after lftp restart.
              Default is true.

       cmd:save-rl-history (boolean)
              when  true, lftp saves readline history to ~/.lftp/rl_history on
              exit.  Default is true.

       cmd:set-term-status (boolean)
              when true, lftp  updates  terminal  status  if  supported  (e.g.
              xterm).  The  closure for this setting is the terminal type from
              TERM environment variable.

       cmd:status-interval (timeinterval)
              the time interval between status updates.

       cmd:stifle-rl-history (number)
              the number of lines to keep in readline history.

       cmd:term-status (string)
              the format string to use to display terminal status. The closure
              for  this  setting  is  the  terminal type from TERM environment
              variable. Default uses ``tsl'' and ``fsl'' termcap values.

              The following escapes are supported:

                   \a   bell
                   \e   escape
                   \n   new line
                   \s   "lftp"
                   \v   lftp version
                   \T   the status string

       cmd:time-style (string)
              This setting is the default value for cls --time-style option.

       cmd:trace (boolean)
              when true, lftp prints the commands it executes (like sh -x).

       cache:cache-empty-listings (boolean)
              When false, empty listings are not cached.

       cache:enable (boolean)
              When false, cache is disabled.

       cache:expire (time interval)
              Positive cache entries expire in this time interval.

       cache:expire-negative (time interval)
              Negative cache entries expire in this time interval.

       cache:size (number)
              Maximum cache size. When exceeded, oldest cache entries will  be
              removed from cache.

       cmd:remote-completion (boolean)
              a boolean to control whether or not lftp uses remote completion.

       cmd:verify-host (boolean)
              if  true, lftp resolves host name immediately in `open' command.
              It is also possible to  skip  the  check  for  a  single  `open'
              command if `&' is given, or if ^Z is pressed during the check.

       cmd:verify-path (boolean)
              if true, lftp checks the path given in `cd' command.  It is also
              possible to skip the check for a single `cd' command if  `&'  is
              given, or if ^Z is pressed during the check.  Examples:
                   set cmd:verify-path/hftp://* false
                   cd directory &

       cmd:verify-path-cached (boolean)
              When  false,  `cd'  to  a directory known from cache as existent
              will  succeed  immediately.   Otherwise  the  verification  will
              depend on cmd:verify-path setting.

       color:use-color (tri-boolean)
              when  true,  cls  command  and  completion  output  colored file
              listings according to color:dir-colors  setting.   When  set  to
              auto, colors are used when output is a terminal.

       color:dir-colors (string)
              file   listing  color  description.  By  default  the  value  of
              LS_COLORS environment variable is used. See dircolors(1).

       dns:SRV-query (boolean)
              query for SRV records and use them before gethostbyname. The SRV
              records  are  only used if port is not explicitly specified. See
              RFC2052 for details.

       dns:cache-enable (boolean)
              enable DNS cache. If it is off, lftp  resolves  host  name  each
              time it reconnects.

       dns:cache-expire (time interval)
              time   to   live   for   DNS   cache   entries.  It  has  format
              <number><unit>+,  e.g.   1d12h30m5s  or  just  36h.  To  disable
              expiration, set it to `inf' or `never'.

       dns:cache-size (number)
              maximum number of DNS cache entries.

       dns:fatal-timeout (time interval)
              limit the time for DNS queries. If DNS server is unavailable too
              long, lftp will fail to  resolve  a  given  host  name.  Set  to
              `never' to disable.

       dns:order (list of protocol names)
              sets  the  order of DNS queries. Default is ``inet6 inet'' which
              means first look up address in inet6 family, then inet  and  use
              them  in  that  order.  To disable inet6 (AAAA) lookup, set this
              variable to ``inet''.

       dns:use-fork (boolean)
              if true, lftp will fork before resolving host  address.  Default
              is true.

       dns:max-retries (number)
              If  zero, there is no limit on the number of times lftp will try
              to lookup an address.  If > 0, lftp will try only this number of
              times to look up an address of each address family in dns:order.

       file:charset (string)
              local character set. It is set from current locale initially.

       fish:charset (string)
              the  character  set used by fish server in requests, replies and
              file listings.  Default is empty which means the same as local.

       fish:connect-program (string)
              the program to use for connecting to remote  server.  It  should
              support `-l' option for user name, `-p' for port number. Default
              is `ssh -a -x'. You can set it to `rsh', for example.

       fish:shell (string)
              use specified shell on server side. Default is /bin/sh. On  some
              systems,   /bin/sh   exits  when  doing  cd  to  a  non-existent
              directory. lftp can handle that but it has to reconnect. Set  it
              to /bin/bash for such systems if bash is installed.

       ftp:acct (string)
              Send  this  string  in  ACCT  command after login. The result is
              ignored.  The closure for this setting has format user@host.

       ftp:anon-pass (string)
              sets the password used for anonymous ftp access  authentication.
              Default is "lftp@".

       ftp:anon-user (string)
              sets the user name used for anonymous ftp access authentication.
              Default is "anonymous".

       ftp:auto-sync-mode (regex)
              if first server message matches this regex, turn  on  sync  mode
              for that host.

       ftp:charset (string)
              the  character  set  used by ftp server in requests, replies and
              file listings.  Default is empty which means the same as  local.
              This setting is only used when the server does not support UTF8.

       ftp:client (string)
              the  name  of ftp client to send with CLNT command, if supported
              by server.  If it is empty, then no CLNT command will be sent.

       ftp:bind-data-socket (boolean)
              bind data socket to the  interface  of  control  connection  (in
              passive  mode).   Default  is  true,  exception  is the loopback
              interface.

       ftp:fix-pasv-address (boolean)
              if true, lftp will try to correct address returned by server for
              PASV  command  in  case when server address is in public network
              and PASV returns an address from a private network. In this case
              lftp would substitute server address instead of the one returned
              by PASV command, port number would not be changed.   Default  is
              true.

       ftp:fxp-passive-source (boolean)
              if  true,  lftp  will try to set up source ftp server in passive
              mode first, otherwise destination one. If first  attempt  fails,
              lftp  tries  to  set  them  up  the  other  way.  If  the  other
              disposition fails too, lftp falls back to plain copy.  See  also
              ftp:use-fxp.

       ftp:home (string)
              Initial directory. Default is empty string which means auto. Set
              this to `/' if you don't like the look of %2F in ftp  URLs.  The
              closure for this setting has format user@host.

       ftp:ignore-pasv-address (boolean)
              If true, lftp uses control connection address instead of the one
              returned in PASV reply for data connection. This can  be  useful
              for broken NATs.  Default is false.

       ftp:list-empty-ok (boolean)
              if  set  to false, empty lists from LIST command will be treated
              as incorrect, and another method (NLST) will be used.

       ftp:list-options (string)
              sets options which are always appended to LIST command.  It  can
              be  useful  to  set  this  to  `-a'  if server does not show dot
              (hidden) files by default.  Default is empty.

       ftp:nop-interval (seconds)
              delay between NOOP commands when downloading  tail  of  a  file.
              This  is  useful  for ftp servers which send "Transfer complete"
              message before  flushing  data  transfer.  In  such  cases  NOOP
              commands can prevent connection timeout.

       ftp:passive-mode (boolean)
              sets  passive  ftp  mode. This can be useful if you are behind a
              firewall or a dumb masquerading router.  In  passive  mode  lftp
              uses  PASV command, not the PORT command which is used in active
              mode. In passive mode lftp itself makes the data  connection  to
              the  server; in active mode the server connects to lftp for data
              transfer. Passive mode is the default.

       ftp:port-ipv4 (ipv4 address)
              specifies an IPv4 address to send with PORT command. Default  is
              empty  which  means  to send the address of local end of control
              connection.

       ftp:port-range (from-to)
              allowed port range for  active  mode.   Format  is  min-max,  or
              `full' or `any' to indicate any port. Default is `full'.

       ftp:prefer-epsv (boolean)
              use EPSV as preferred passive mode. Default is `false'.

       ftp:proxy (URL)
              specifies  ftp proxy to use.  To disable proxy set this to empty
              string. Note that it is an ftp proxy which  uses  ftp  protocol,
              not  ftp  over  http.  Default  value  is taken from environment
              variable ftp_proxy if it starts with  ``ftp://''.  If  your  ftp
              proxy requires authentication, specify user name and password in
              the URL.  If ftp:proxy starts with http://  then  hftp  protocol
              (ftp over http proxy) is used instead of ftp automatically.

       ftp:proxy-auth-type (string)
              When       set       to       ``joined'',       lftp       sends
              ``user@proxy_user@ftp.example.org'' as user name to  proxy,  and
              ``password@proxy_password'' as password.

              When  set  to ``joined-acct'', lftp sends ``user@ftp.example.org
              proxy_user'' (with space)  as  user  name  to  proxy.  The  site
              password  is sent as usual and the proxy password is expected in
              the following ACCT command.

              When set to ``open'', lftp first  sends  proxy  user  and  proxy
              password  and  then  ``OPEN ftp.example.org'' followed by ``USER
              user''.  The site password is then sent as usual.

              When set to ``user'' (default), lftp first sends proxy user  and
              proxy  password  and then ``user@ftp.example.org'' as user name.
              The site password is then sent as usual.

              When  set  to  ``proxy-user@host'',  lftp  first  sends   ``USER
              proxy_user@ftp.example.org'', then proxy password. The site user
              and password are then sent as usual.

       ftp:rest-list (boolean)
              allow usage of REST command before LIST command. This  might  be
              useful  for  large  directories,  but  some ftp servers silently
              ignore REST before LIST.

       ftp:rest-stor (boolean)
              if false, lftp will not try to use REST before STOR. This can be
              useful  for  some  buggy servers which corrupt (fill with zeros)
              the file if REST followed by STOR is used.

       ftp:retry-530 (regex)
              Retry on server reply 530 for PASS command if text matches  this
              regular   expression.    This   setting   should  be  useful  to
              distinguish between overloaded server (temporary condition)  and
              incorrect password (permanent condition).

       ftp:retry-530-anonymous (regex)
              Additional   regular   expression   for  anonymous  login,  like
              ftp:retry-530.

       ftp:site-group (string)
              Send this string in SITE GROUP command after login.  The  result
              is ignored.  The closure for this setting has format user@host.

       ftp:skey-allow (boolean)
              allow  sending  skey/opie reply if server appears to support it.
              On by default.

       ftp:skey-force (boolean)
              do not send plain text password over the network, use  skey/opie
              instead. If skey/opie is not available, assume failed login. Off
              by default.

       ftp:ssl-allow (boolean)
              if true, try to negotiate SSL connection  with  ftp  server  for
              non-anonymous  access.  Default  is  true.  This  and  other ssl
              settings are only available if lftp was compiled with an ssl/tls
              library.

       ftp:ssl-data-use-keys (boolean)
              if  true,  lftp loads ssl:key-file for protected data connection
              too. When false, it does not, and the server can match data  and
              control connections by session ID.  Default is true.

       ftp:ssl-force (boolean)
              if  true,  refuse to send password in clear when server does not
              support SSL.  Default is false.

       ftp:ssl-protect-data (boolean)
              if true, request ssl connection for data transfers. This is cpu-
              intensive but provides privacy. Default is false.

       ftp:ssl-protect-fxp (boolean)
              if  true,  request  ssl connection for data transfer between two
              ftp servers in FXP mode. CPSV or SSCN command will  be  used  in
              that  case.  If ssl connection fails for some reason, lftp would
              try unprotected FXP transfer unless ftp:ssl-force is set for any
              of the two servers. Default is false.

       ftp:ssl-protect-list (boolean)
              if true, request ssl connection for file list transfers. Default
              is true.

       ftp:ssl-use-ccc (boolean)
              if true, lftp would issue CCC command after logon, thus  disable
              ssl protection layer on control connection.

       ftp:stat-interval (time interval)
              interval between STAT commands. Default is 1 second.

       ftp:sync-mode (boolean)
              if  true,  lftp  will  send  one  command at a time and wait for
              response. This might be useful if you  are  using  a  buggy  ftp
              server  or router. When it is off, lftp sends a pack of commands
              and waits for responses - it speeds up operation when round trip
              time  is  significant.   Unfortunately it does not work with all
              ftp servers and some routers have troubles with it, so it is  on
              by default.

       ftp:timezone (string)
              Assume  this  timezone  for  time  in  listings returned by LIST
              command.  This setting can be GMT  offset  [+|-]HH[:MM[:SS]]  or
              any     valid     TZ     value     (e.g.     Europe/Moscow    or
              MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT.  Set  it  to  an
              empty  value  to  assume local timezone specified by environment
              variable TZ.

       ftp:trust-feat (string)
              When true, assume that FEAT returned data are correct and  don't
              use common protocol extensions like SIZE, MDTM, REST if they are
              not listed.  Default is false.

       ftp:use-abor (boolean)
              if false, lftp does  not  send  ABOR  command  but  closes  data
              connection immediately.

       ftp:use-allo (boolean)
              when  true (default), lftp sends ALLO command before uploading a
              file.

       ftp:use-feat (boolean)
              when  true  (default),  lftp  uses  FEAT  command  to  determine
              extended features of ftp server.

       ftp:use-fxp (boolean)
              if  true,  lftp will try to set up direct connection between two
              ftp servers.

       ftp:use-hftp (boolean)
              when ftp:proxy points to an http  proxy,  this  setting  selects
              hftp  method  (GET,  HEAD)  when  true,  and CONNECT method when
              false. Default is true.

       ftp:use-ip-tos (boolean)
              when true, lftp uses IPTOS_LOWDELAY for control  connection  and
              IPTOS_THROUGHPUT for data connections.

       ftp:lang (boolean)
              the  language  selected  with  LANG  command,  if  supported  as
              indicated by FEAT response. Default is empty which means  server
              default.

       ftp:use-mdtm (boolean)
              when  true  (default),  lftp uses MDTM command to determine file
              modification time.

       ftp:use-mdtm-overloaded (boolean)
              when true, lftp uses two  argument  MDTM  command  to  set  file
              modification time on uploaded files. Default is false.

       ftp:use-site-idle (boolean)
              when   true,  lftp  sends  `SITE  IDLE'  command  with  net:idle
              argument. Default is false.

       ftp:use-site-utime (boolean)
              when true, lftp sends 5-argument `SITE  UTIME'  command  to  set
              file modification time on uploaded files. Default is true.

       ftp:use-site-utime2 (boolean)
              when  true,  lftp  sends  2-argument `SITE UTIME' command to set
              file modification time on uploaded files. Default is  true.   If
              5-argument  `SITE  UTIME' is also enabled, 2-argument command is
              tried first.

       ftp:use-size (boolean)
              when true (default), lftp uses SIZE command  to  determine  file
              size.

       ftp:use-stat (boolean)
              if  true,  lftp  sends STAT command in FXP mode transfer to know
              how much data has been transferred. See also  ftp:stat-interval.
              Default is true.

       ftp:use-stat-for-list (boolean)
              when  true,  lftp  uses STAT instead of LIST command. By default
              `.' is used as STAT argument. Using STAT, lftp  avoids  creating
              data  connection  for  directory  listing.  Some servers require
              special options for STAT, use ftp:list-options to  specify  them
              (e.g. -la).

       ftp:use-telnet-iac (boolean)
              when  true  (default),  lftp uses TELNET IAC command and follows
              TELNET protocol as specified in RFC959. When false, it does  not
              follow TELNET protocol and thus does not double 255 (0xFF, 0377)
              character and does not prefix ABOR and STAT commands with TELNET
              IP+SYNCH signal.

       ftp:use-tvfs (tri-boolean)
              When  set  to auto, usage of TVFS feature depends on FEAT server
              reply. Otherwise this setting tells whether use it  or  not.  In
              short,  if a server supports TVFS feature then it uses unix-like
              paths.

       ftp:use-quit (boolean)
              if true, lftp sends QUIT before disconnecting from  ftp  server.
              Default is true.

       ftp:verify-address (boolean)
              verify  that  data  connection comes from the network address of
              control  connection  peer.  This  can  possibly   prevent   data
              connection   spoofing   which   can  lead  to  data  corruption.
              Unfortunately, this  can  fail  for  certain  ftp  servers  with
              several  network  interfaces,  when  they  do  not  set outgoing
              address on data socket, so it is disabled by default.

       ftp:verify-port (boolean)
              verify that data connection has port 20 (ftp-data) on its remote
              end.   This  can  possibly  prevent  data connection spoofing by
              users of remote host. Unfortunately, too many windows  and  even
              unix  ftp  servers forget to set proper port on data connection,
              thus this check is off by default.

       ftp:web-mode (boolean)
              disconnect after closing data connection. This can be useful for
              totally broken ftp servers. Default is false.

       ftps:initial-prot (string)
              specifies  initial  PROT setting for FTPS connections. Should be
              one of: C, S, E, P, or  empty.  Default  is  empty  which  means
              unknown,  so that lftp will use PROT command unconditionally. If
              PROT command turns out to be unsupported, then Clear mode  would
              be assumed.

       hftp:cache (boolean)
              allow server/proxy side caching for ftp-over-http protocol.

       hftp:cache-control (string)
              specify corresponding HTTP request header.

       hftp:proxy (URL)
              specifies  http  proxy  for  ftp-over-http  protocol (hftp). The
              protocol hftp cannot  work  without  a  http  proxy,  obviously.
              Default value is taken from environment variable ftp_proxy if it
              starts with ``http://'',  otherwise  from  environment  variable
              http_proxy.   If your ftp proxy requires authentication, specify
              user name and password in the URL.

       hftp:use-authorization (boolean)
              if set to off, lftp will send password as part  of  URL  to  the
              proxy.  This  may  be  required  for some proxies (e.g. M-soft).
              Default  is  on,  and  lftp  will  send  password  as  part   of
              Authorization header.

       hftp:use-head (boolean)
              if  set to off, lftp will try to use `GET' instead of `HEAD' for
              hftp protocol.  While this is slower, it may allow lftp to  work
              with  some  proxies  which  don't understand or mishandle ``HEAD
              ftp://'' requests.

       hftp:use-mkcol (boolean)
              if set to off, lftp will try to use `PUT' instead of `MKCOL'  to
              create directories with hftp protocol. Default is off.

       hftp:use-propfind (boolean)
              if  set  to  off,  lftp  will  not  try to use `PROPFIND' to get
              directory contents with hftp protocol  and  use  `GET'  instead.
              Default is off.

       hftp:use-type (boolean)
              If  set to off, lftp won't try to append `;type=' to URLs passed
              to proxy.   Some  broken  proxies  don't  handle  it  correctly.
              Default is on.

       http:accept, http:accept-charset, http:accept-language (string)
              specify corresponding HTTP request headers.

       http:authorization (string)
              the  authorization to use by default, when no user is specified.
              The format is ``user:password''. Default is empty which means no
              authorization.

       http:cache (boolean)
              allow server/proxy side caching.

       http:cache-control (string)
              specify corresponding HTTP request header.

       http:cookie (string)
              send this cookie to server. A closure is useful here:
                   set cookie/www.somehost.com "param=value"

       http:post-content-type (string)
              specifies  value  of  Content-Type  http request header for POST
              method.  Default is ``application/x-www-form-urlencoded''.

       http:proxy (URL)
              specifies http proxy. It is  used  when  lftp  works  over  http
              protocol.   Default  value  is  taken  from environment variable
              http_proxy.  If your proxy requires authentication, specify user
              name and password in the URL.

       http:put-method (PUT or POST)
              specifies which http method to use on put.

       http:put-content-type (string)
              specifies  value  of  Content-Type  http  request header for PUT
              method.

       http:referer (string)
              specifies value for Referer http request header. Single dot  `.'
              expands  to  current directory URL. Default is `.'. Set to empty
              string to disable Referer header.

       http:set-cookies (boolean)
              if true, lftp modifies  http:cookie  variables  when  Set-Cookie
              header is received.

       http:use-mkcol (boolean)
              if  set to off, lftp will try to use `PUT' instead of `MKCOL' to
              create directories with http protocol. Default is on.

       http:use-propfind (boolean)
              if set to off, lftp will  not  try  to  use  `PROPFIND'  to  get
              directory  contents  with  http  protocol and use `GET' instead.
              Default is on.

       http:user-agent (string)
              the string lftp sends in User-Agent header of HTTP request.

       https:proxy (string)
              specifies https proxy. Default value is taken  from  environment
              variable https_proxy.

       mirror:dereference (boolean)
              when  true,  mirror  will dereference symbolic links by default.
              You can override  it  by  --no-dereference  option.  Default  if
              false.

       mirror:exclude-regex (regex)
              specifies  default  exclusion  pattern.  You  can override it by
              --include option.

       mirror:include-regex (regex)
              specifies default inclusion  pattern.  It  is  used  just  after
              mirror:exclude-regex   is   applied.   It   is   never  used  if
              mirror:exclude-regex is empty.

       mirror:no-empty-dirs (boolean)
              when  true,  mirror  doesn't  create  empty  directories   (like
              --no-empty-dirs option).

       mirror:order (list of patterns)
              specifies  order  of file transfers. E.g. setting this to "*.sfv
              *.sum" makes mirror to transfer files matching *.sfv first, then
              ones  matching  *.sum  and  then  all  other  files.  To process
              directories after other files, add "*/" to end of pattern list.

       mirror:parallel-directories (boolean)
              if true, mirror will start processing of several directories  in
              parallel  when  it  is  in  parallel  mode.  Otherwise,  it will
              transfer files from a single directory before  moving  to  other
              directories.

       mirror:parallel-transfer-count (number)
              specifies  number  of  parallel  transfers  mirror is allowed to
              start. Default is  1.   You  can  override  it  with  --parallel
              option.

       mirror:set-permissions (boolean)
              When  set  to  off,  mirror won't try to copy file and directory
              permissions.  You can override it by --perms option. Default  is
              on.

       mirror:skip-noaccess (boolean)
              when  true,  mirror  does  not  try  to download files which are
              obviously unaccessible by the permission mask. Defaule is false.

       mirror:use-pget-n (number)
              specifies -n option for pget  command  used  to  transfer  every
              single file under mirror. Default is 1 which disables pget.

       module:path (string)
              colon  separated list of directories to look for modules. Can be
              initialized by environment variable LFTP_MODULE_PATH. Default is
              `PKGLIBDIR/VERSION:PKGLIBDIR'.

       net:connection-limit (number)
              maximum  number  of  concurrent  connections to the same site. 0
              means unlimited.

       net:connection-takeover (boolean)
              if true, foreground connections have  priority  over  background
              ones  and  can  interrupt  background  transfers  to  complete a
              foreground operation.

       net:idle (time interval)
              disconnect from server  after  this  idle  time.  Default  is  3
              minutes.

       net:limit-rate (bytes per second)
              limit  transfer  rate on data connection. 0 means unlimited. You
              can specify two numbers separated by colon to limit download and
              upload rate separately.

       net:limit-max (bytes)
              limit accumulating of unused limit-rate. 0 means twice of limit-
              rate.

       net:limit-total-rate (bytes per second)
              limit  transfer  rate  of  all  connections  in  sum.  0   means
              unlimited.  You  can  specify  two numbers separated by colon to
              limit download and upload rate separately.   Note  that  sockets
              have receive buffers on them, this can lead to network link load
              higher than this rate limit just after transfer  beginning.  You
              can  try  to  set net:socket-buffer to relatively small value to
              avoid this.

       net:limit-total-max (bytes)
              limit accumulating of unused limit-total-rate. 0 means twice  of
              limit-total-rate.

       net:max-retries (number)
              the maximum number of sequential retries of an operation without
              success.  0 means unlimited.

       net:no-proxy (string)
              contains comma separated list of domains for which proxy  should
              not  be  used.   Default  is  taken  from  environment  variable
              no_proxy.

       net:persist-retries (number)
              ignore this number of hard errors. Useful to login to buggy  ftp
              servers which reply 5xx when there is too many users.

       net:reconnect-interval-base (seconds)
              sets  the  base minimal time between reconnects. Actual interval
              depends  on  net:reconnect-interval-multiplier  and  number   of
              attempts to perform an operation.

       net:reconnect-interval-max (seconds)
              sets  maximum  reconnect  interval.  When current interval after
              multiplication by net:reconnect-interval-multiplier reachs  this
              value  (or  exceeds  it),  it  is  reset  back to net:reconnect-
              interval-base.

       net:reconnect-interval-multiplier (real number)
              sets multiplier by which base interval is multiplied  each  time
              new  attempt  to  perform  an operation fails. When the interval
              reachs maximum, it is reset to base  value.  See  net:reconnect-
              interval-base and net:reconnect-interval-max.

       net:socket-bind-ipv4 (ipv4 address)
              bind  all  IPv4 sockets to specified address. This can be useful
              to select a specific network interface to use. Default is  empty
              which  means  not  to  bind  IPv4 sockets, operating system will
              choose an address automatically using routing table.

       net:socket-bind-ipv6 (ipv6 address)
              the same for IPv6 sockets.

       net:socket-buffer (bytes)
              use given size for SO_SNDBUF and  SO_RCVBUF  socket  options.  0
              means system default.

       net:socket-maxseg (bytes)
              use  given  size for TCP_MAXSEG socket option. Not all operating
              systems support this option, but linux does.

       net:timeout (time interval)
              sets the network protocol timeout.

       pget:default-n (number)
              default number of chunks to split the file to in pget.

       pget:save-status (time interval)
              save pget transfer status this often. Set to `never' to  disable
              saving  of  the status file.  The status is saved to a file with
              suffix .lftp-pget-status.

       sftp:charset (string)
              the character set used by sftp server in  file  names  and  file
              listings.   Default is empty which means the same as local. This
              setting is only used for  sftp  protocol  version  prior  to  4.
              Version 4 and later always use UTF-8.

       sftp:connect-program (string)
              the  program  to  use for connecting to remote server. It should
              support `-l' option for user name, `-p' for port number. Default
              is `ssh -a -x'. You can set it to `rsh', for example.

       sftp:max-packets-in-flight (number)
              The maximum number of unreplied packets in flight. If round trip
              time  is  significant,  you  should  increase  this  and   size-
              read/size-write. Default is 16.

       sftp:protocol-version (number)
              The  protocol  number  to  negotiate.  Default  is 4. The actual
              protocol version used depends on server.

       sftp:server-program (string)
              The server program implementing SFTP protocol. If  it  does  not
              contain  a  slash  `/', it is considered a ssh2 subsystem and -s
              option  is  used  when  starting  connect-program.   Default  is
              `sftp'. You can use rsh as transport level protocol like this:
                   set sftp:connect-program rsh
                   set sftp:server-program /usr/libexec/openssh/sftp-server
              Similarly you can run sftp over ssh1.

              if set to yes, then verify server's certificate to be signed  by
              a   known  Certificate  Authority  and  not  be  on  Certificate
              Revocation List.

       torrent:ip (ipv4 address)
              IP address to send to the tracker. Specify it if you  are  using
              an http proxy.

              IPv6  address  to  send  to the tracker. By default, first found
              global unicast address is used.

       torrent:max-peers (number)
              maximum number of peers for a  torrent.  Least  used  peers  are
              removed to maintain this limit.

       torrent:port-range (from-to)

              when a torrent starts.

       torrent:seed-max-time (time interval)
              maximum seed time. After this period of time a complete  torrent
              shuts  down independently of ratio. It can be set to infinity if
              needed.

       torrent:seed-min-peers (number)
              minimum number of peers when the torrent is complete.  If  there

       torrent:stop-on-ratio (real number)
              torrent stops when it's complete and ratio reached this number.

       xfer:clobber (boolean)
              if this setting is off, get commands will not overwrite existing
              files and generate an error instead.

       xfer:destination-directory (path or URL to directory)
              This setting is used as default  -O  option  for  get  and  mget
              commands.   Default  is empty, which means current directory (no
              -O option).

       xfer:disk-full-fatal (boolean)
              when true, lftp aborts a transfer if it cannot write target file
              because  of  full disk or quota; when false, lftp waits for disk
              space to be freed.

       xfer:eta-period (seconds)
              the period over which weighted average  rate  is  calculated  to
              produce ETA.

              show terse ETA (only high order parts). Default is true.

       xfer:log (boolean)
              when  true,  lftp  logs  transfers  to a file from xfer:log-file
              setting.

       xfer:log-file (boolean)
              the file to log transfers to. Default is ~/.lftp/transfer_log.

       xfer:make-backup (boolean)
              when true, lftp renames pre-existing file  adding  ``~''  suffix
              instead of overwriting it.

       xfer:max-redirections (number)
              maximum   number   of  redirections.  This  can  be  useful  for
              downloading over HTTP.  0 prohibits redirections.

       xfer:rate-period (seconds)
              the period over which weighted average rate is calculated to  be
              shown.

       xfer:verify (boolean)
              when  true, verify-command is launched after successful transfer
              to validate file integrity.  Zero  exit  code  of  that  command
              should indicate correctness of the file.

       xfer:verify-command (string)
              the command to validate file integrity. The only argument is the
              path to the file.

       The name of a variable can be abbreviated unless it becomes  ambiguous.
       The  prefix  before  `:'  can  be omitted too. You can set one variable
       several times for different closures, and thus you can get a particular
       settings  for  particular  state.  The closure is to be specified after
       variable name separated with slash `/'.

       The  closure  for  `dns:',  `net:',  `ftp:',  `http:',  `hftp:'  domain
       variables  is  currently  just  the  host name as you specify it in the
       `open' command (with some exceptions where closure is meaningless, e.g.
       dns:cache-size).   For  some  `cmd:'  domain  variables  the closure is
       current URL without path.  For other  variables  it  is  not  currently
       used. See examples in the sample lftp.conf.

       Certain  commands  and  settings take a time interval parameter. It has
       the format Nx[Nx...], where N is time amount (floating point) and x  is
       time  unit: d - days, h - hours, m - minutes, s - seconds. Default unit
       is second. E.g. 5h30m or 5.5h.  Also the interval  can  be  `infinity',
       `inf',  `never',  `forever'  -  it means infinite interval. E.g. `sleep
       forever' or `set dns:cache-expire never'.

       Boolean settings can be one of (true, on, yes, 1, +) for a  True  value
       or one of (false, off, no, 0, -) for a False value.

       Tri-boolean settings have either a boolean value or `auto'.

       Integer  settings can have a suffix: k - kibi, m - mebi, g - gigi, etc.
       They can also have a prefix: 0 - octal, 0x - hexadecimal.

   FTP asynchronous mode (pipelining)
       Lftp can speed up ftp operations by sending several  commands  at  once
       and  then  checking  all  the  responses.  See  ftp:sync-mode variable.
       Sometimes this does not work, thus synchronous mode is the default. You
       can try to turn synchronous mode off and see if it works for you. It is
       known that some network software dealing with address translation works
       incorrectly in the case of several FTP commands in one network packet.

       RFC959  says:  ``The  user-process  sending  another command before the
       completion reply would be in  violation  of  protocol;  but  server-FTP
       processes  should  queue  any  commands  that  arrive while a preceding
       command is in progress''. Also, RFC1123 says: ``Implementors  MUST  NOT
       assume  any  correspondence  between  READ  boundaries  on  the control
       connection and the Telnet EOL sequences (CR LF).'' and ``a single  READ
       from the control connection may include more than one FTP command''.

       So  it  must  be safe to send several commands at once, which speeds up
       operation a lot and seems to work with  all  Unix  and  VMS  based  ftp
       servers.  Unfortunately,  windows  based  servers  often  cannot handle
       several commands in one packet, and so cannot some broken routers.

OPTIONS

       -d     Switch on debugging mode.

       -e commands
              Execute given commands and don't exit.

       -p port
              Use the given port to connect.

       -u user[,pass]
              Use the given username and  password  to  connect.  Remember  to
              quote  the password properly in the shell.  Also note that it is
              not secure to specify the password on command line, use ~/.netrc
              file.   Alternatively  you  can  use  ssh-based  protocols  with
              authorized keys, so you don't have to enter a password.

       -f script_file
              Execute commands in the file and exit.  This option must be used
              alone without other arguments.

       -c commands
              Execute  the  given commands and exit. Commands can be separated
              with a semicolon, `&&' or `||'. Remember to quote  the  commands
              argument  properly in the shell.  This option must be used alone
              without other arguments.

ENVIRONMENT VARIABLES

       The following environment variables are processed by lftp:

       HOME   Used for (local) tilde (`~') expansion

       SHELL  Used by the ! command to determine the shell to run.

       PAGER  This should be the name of the pager to use.  It's used  by  the
              more and zmore commands.

       http_proxy, https_proxy
              Used  to  set  initial  http:proxy,  hftp:proxy  and https:proxy
              variables.

       ftp_proxy
              Used to set initial ftp:proxy or hftp:proxy variables, depending
              on URL protocol used in this environment variable.

       no_proxy
              Used to set initial net:no-proxy variable.

       LFTP_MODULE_PATH
              Used to set initial module:path variable.

       LFTP_HOME
              Used   to   locate   the  directory  that  stores  user-specific
              configuration files.  If unset, ~/.lftp will be used.

       LS_COLORS
              used to set initial color:dir-colors variable.

FILES

       /etc/lftp.conf
              system-wide   startup   file.   Actual   location   depends   on
              --sysconfdir  configure  option. It is /etc when prefix is /usr,
              /usr/local/etc by default.

       ~/.lftp/rc, ~/.lftprc
              These files are executed on lftp startup after /etc/lftp.conf.

       ~/.lftp/log
              The  file  things  are  logged  to  when  lftp  moves  into  the
              background in nohup mode.

       ~/.lftp/transfer_log
              The file transfers are logged to when xfer:log setting is set to
              `yes'.  The location can be changed by xfer:log-file setting.

       ~/.lftp/bookmarks
              The file is used to store lftp's bookmarks.   See  the  bookmark
              command.

       ~/.lftp/cwd_history
              The file is used to store last working directories for each site
              visited.

       ~/.lftp/bg/
              The directory is used to store named  sockets  for  backgrounded
              lftp processes.

       ~/.netrc
              The  file  is consulted to get default login and password to ftp
              server.  Passwords are also searched here if an  URL  with  user
              name but with no password is used.
