snexpire,v0.3.8(8)					      System Manager's Manual						snexpire,v0.3.8(8)

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  excep-
       tion  if the expiration age is set to 0, then even this last file will be expired and subsequent article numbers will start from the begin-
       ning.  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.
