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 SIG-INT. SIGINT.
INT.
-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 con-figurations configurations
figurations the large number of directories created may require attention. If your configura-tion configuration
tion 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 speci-fied specified
fied 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.
