htcacheclean - Clean up the disk cache
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.

    -dinterval

    -llimit
Options
- -dinterval
- Daemonize and repeat cache cleaning every interval minutes.
    This option is mutually exclusive with the -D,-vand-roptions. To shutdown the daemon cleanly, just send it aSIGTERMorSIGINT.
- -D
- Do a dry run and don't delete anything. This option is mutually
    exclusive with the -doption.
- -v
- Be verbose and print statistics. This option is mutually exclusive
    with the -doption.
- -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 -doption and implies the-toption.
- -n
- Be nice. This causes slower processing in favour of other
    processes. htcachecleanwill 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 CacheRootdirective.
- -llimit
- Specify limit as the total disk cache size limit. The value
    is expressed in bytes by default (or attaching Bto the number). AttachKfor Kbytes orMfor MBytes.
- -i
- Be intelligent and run only when there was a modification of the disk
    cache. This option is only possible together with the -doption.
Exit Status
htcacheclean returns a zero status ("true") if all
    operations were successful, 1 otherwise.
