htcacheclean



SYNOPSIS
       htcacheclean [ -D ] [ -v ] [ -t ] [ -r ] [ -n ] -ppath -llimit


       htcacheclean [ -n ] [ -t ] [ -i ] -dinterval -ppath -llimit



SUMMARY
       htcacheclean  is  used  to  keep  the  size of mod_disk_cache's storage
       within a certain limit. This tool can run either manually or in  daemon
       mode.  When  running  in  daemon  mode, it sleeps in the background and
       checks the cache directories at regular intervals for cached content to
       be removed. You can stop the daemon cleanly by sending it a TERM or INT
       signal.



OPTIONS
       -dinterval
              Daemonize and repeat cache cleaning every interval minutes. This
              option  is mutually exclusive with the -D, -v and -r options. To
              shutdown the daemon cleanly, just send it a SIGTERM or SIGINT.

       -D     Do a dry run and don't delete anything. This option is  mutually
              exclusive with the -d option.

       -v     Be  verbose and print statistics. This option is mutually exclu-
              sive with the -d option.

       -r     Clean thoroughly. This assumes that the Apache web server is not
              running  (otherwise  you  may  get  garbage  in the cache). This
              option is mutually exclusive with the -d option and implies  the
              -t option.

       -n     Be  nice.  This causes slower processing in favour of other pro-
              cesses. htcacheclean will sleep from time to time  so  that  (a)
              the  disk  IO  will  be  delayed and (b) the kernel can schedule
              other processes in the meantime.

       -t     Delete all empty directories. By default only  cache  files  are
              removed,  however  with  some configurations the large number of
              directories created may require attention. If your configuration
              requires  a  very large number of directories, to the point that
              inode or file allocation table exhaustion may become  an  issue,
              use of this option is advised.

       -ppath Specify  path  as  the  root  directory  of the disk cache. This
              should be the same value as specified with the CacheRoot  direc-
              tive.

       -llimit
