NAME

       snexpire - expire news under the sn system.

SYNOPSIS

       snexpire [-v] [-exp] newsgroup [[-exp] newsgroup]...

DESCRIPTION

       snexpire  expires news in the sn news system, one article file (=10 articles, compile time
       default) at a time.  snexpire always leaves behind at least  one  article  file,  so  that
       newly  entered  articles will have numbers not overlapping previously used numbers.  As an
       exception if the expiration age is set to 0, then even this last file will be expired  and
       subsequent article numbers will start from the beginning.  You will need to be root or own
       /var/spool/sn to run snexpire.

OPTIONS

       -v Output a line for each article expired.  The format of this line is  the  same  as  for
       snscan.

ARGUMENTS

       snexpire expires all newsgroups named on the command line.  Each newsgroup may be preceded
       by -exp to control the expiration age.  exp is of the form #[hdwmy] where # is  a  number,
       followed  by  one  of the characters h,d,w,m,y representing hours, days, weeks, months and
       years.  The default for -exp is a compile-time fixed.  Each [-exp]  applies  to  the  next
       newsgroup  only,  any newsgroups after that one get default treatment unless overridden by
       another [-exp].

FILES MODIFIED

       /var/spool/sn/newsgroup/.times,                     /var/spool/sn/newsgroup/[0123456789]*,
       /var/spool/sn/{.chain,.table}.

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.

FILES

       /var/spool/sn/newsgroup/.expire
              If this exists, its contents are taken to be exp if not overridden by -exp  on  the
              command line.
