| .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\&. |
