NAME

       snscan - display information on articles in the spool
       sncat - display articles in the spool
       sncancel - cancel articles in the spool

SYNOPSIS

       snscan [options] articlespec...
       sncat [options] articlespec...
       sncancel [options] articlespec...
       options: [-n] [-s since] [-o outputfile]

DESCRIPTION

       snscan displays information on all articles specified by articlespec, in the form
              newsgroup serial id
              on a line, one line per article matched.  This output is suitable for feeding to snprimedb.

       sncat  displays the articles specified by articlespec.

       sncancel
              marks articles specified by articlespec as canceled, so they become unavailable to sn programs.

ARGUMENTS

       articlespec defines a broad pattern for articles.  It takes two mutually exclusive forms.

       Specify by newsgroup and serial number
              Here articlespec is
              newsgroup[:range[,range]...]
              where each range is
              serial[-[toserial]]
              (where  toserial  is greater than serial).  If toserial is omitted, then all articles after serial
              are matched.  If both serial and toserial are empty, then only the first  and  last  articles  are
              matched.

       Specify by articles message ID
              Here articlespec is -i id...
              where each id is a message ID, angle brackets optional.

OPTIONS

       -n     This  option  weeds out articles that are aliases.  If an article is crossposted, there will be an
              original copy, the others will be aliases to it.  This option prevents information being displayed
              if it is not from the original copy.

       -ssince
              This  option  weeds  out  articles  that  were  obtained  before  since.   since  is in the format
              year/month/day[:hour:minute] where each is a number.  year may be 2 or 4 digits, and / and  :  can
              be any non-digit character.

       -ooutputfile
              Write  output to outputfile instead of descriptor 1.  Sometimes you just don't feel like using the
              shell.

EXAMPLES

       sncancel linux.lemmings:12
              Cancel article 12 from linux.lemmings.

       snscan linux.lemmings:4,12-
              Display information on article  4,  and  also  articles  12  to  the  most  recent  article,  from
              linux.lemmings.

       sncat -n -s 1998/4/1 linux.lemmings
              Display  all  articles  that  are  not  aliases,  and  which were entered after April 1 1998, from
              linux.lemmings.

       snscan -i '123@myhost'
              Display information on the article whose ID is <123@myhost>, in whichever newsgroup it is found.

FILES

       Each articlespec or id on the command line refers to articles in the news spool located in /var/spool/sn.

ENVIRONMENT VARIABLES

       SNROOT If this is set and is not empty, the value is used in place of  /var/spool/sn,  the  default  news
              spool directory.

EXIT CODES

       snscan  exits  0  on  success,  1 on usage error, 2 on system error, and 3 on other errors.  It is not an
       error to specify an article that does not exist, or which does not meet the since criterion.
