       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 signal.


              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

       -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 directive.

              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 option.


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