.SH "SUMMARY"

.PP

htcacheclean is used to keep the size of mod_disk_cache's storage within a certain limit\&. This tool can be either run manually or in daemon mode\&. When running in daemon mode, it sleeps in the background and checks the cache directories in regular intervals for stuff to be removed\&. You can stop the daemon cleanly, when sending him a TERM or INT signal\&.

.SH "OPTIONS"

.TP

-d\fIinterval\fR

Daemonize and repeat cache cleaning every \fIinterval\fR 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\&.  

.TP

-D

Do a dry run and don't delete anything\&. This option is mutually exclusive with the -d option\&.  

.TP

-v

Be verbose and print statistics\&. This option is mutually exclusive with the -d option\&.  

.TP

-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\&.  

.TP

-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\&.  

.TP

-p\fIpath\fR

Specify \fIpath\fR as the root directory of the disk cache\&. This should be the same value as specified with the CacheRoot directive\&.  

.TP

-l\fIlimit\fR

Specify \fIlimit\fR 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\&.  

.TP

-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\&.  

.SH "EXIT STATUS"

.PP

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