       htcacheclean - Clean up the disk cache


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

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


       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


              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
              exclusive 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
              processes. 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

              Specify  limit  as the total disk cache size limit. The value is
              expressed in bytes by default (or attaching B  to  the  number).
              Attach K for Kbytes or M for MBytes.

       -i     Be intelligent and run only when there was a modification of the
              disk cache. This option is only possible together  with  the  -d


       htcacheclean  returns  a  zero  status  ("true") if all operations were
       successful, 1 otherwise.
