NAME
       lurker-prune — prunes the web-server cache


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


DESCRIPTION
       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 hour.

       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.


OPTIONS
       -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 needed.

       -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 needed.

       -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.
