HTCACHECLEAN(8)


NAME

  htcacheclean - Clean up the disk cache


SYNOPSIS

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

  htcacheclean -b [ -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 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 directive.

  -llimit
       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.


EXIT STATUS

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