       lurker-prune — prunes the web-server cache


       lurker-prune  [-c  <config-file>]   [-f  <frontend>]   [-m <days>]  [-a
       <days>]  [-p -v]


       lurker-prune  prunes  obsolete  or  stale  files  from  the  web-server
       accessible  cache.  This  command must be run at regular intervals from
       eg. a cronjob. If it is not run, then the  lurker  web  interface  will
       appear to not be receiving new mail or have contradictory links between
       pages. A good interval is every 15 minutes and should  not  exceed  one

       Be  aware  that it is possible for an attacker to use up a large amount
       of disk space through lurker. An attacker could request  many  distinct
       lurker web pages each of which is cached, thus using disk space. Please
       setup a quota for the lurker user, read your logs, and follow  whatever
       site-specific policies you have for denial of service.

       A  good  script  to run in parallel with normal lurker-prune use is one
       similar to: if test `du -s /var/www/lurker | cut -f1` -gt  32768;  then
       lurker-prune  -p;  fi This might help guard against a potential denial-
       of-service attack.


       -c config-file
                 Use this config file for lurker settings.

       -f frontend
                 The directory of the lurker frontend cache to clean. You  can
                 selectively purge cache with this option. By default, lurker-
                 prune will clean all frontends specified in the config file.

       -m days   Keep cached files for at most this many days. Any cached file
                 regardless of last access will be deleted after the specified
                 number of days (defaults to 7). Files which are obsolete  due
                 to  new  mail, config changes, or no accesses will be deleted
                 earlier.  Deleted files will be automagically regenerated  if

       -a days   Kill  cache files not accessed for this many days. Any cached
                 file which has not been read from for the specified number of
                 days  (defaults  to  1)  will  be  deleted.  Files  which are
                 obsolete due to new mail or config changes  will  be  deleted
                 earlier.   Deleted files will be automagically regenerated if

       -p        Purge mode. Delete all cache files even if they do not appear
                 to  be  expired.  This  will  only  deletes  files  that  are
                 generated by lurker, and is thus preferable to rm */*.

       -v        Verbose operation. Indicate which files are being deleted and
                 the  reasoning  behind  lurker's  decisions. This can help in
                 tracking down why some files are deleted and not others.
