.SH "SUMMARY"
|
|
|
|
.PP
|
|
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\&.
|
|
|
|
|
|
.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 and implies the -t 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
|
|
-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\&.
|
|
.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\&.
