       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.
