SUMMARY

18       htcacheclean  is  used  to  keep  the  size of mod_disk_cache's storage
19       within a certain limit. This tool can run either manually or in  daemon
20       mode.  When  running  in  daemon  mode, it sleeps in the background and
21       checks the cache directories at regular intervals for cached content to
22       be removed. You can stop the daemon cleanly by sending it a TERM or INT
23       signal.

OPTIONS

28       -dinterval
29              Daemonize and repeat cache cleaning every interval minutes. This
30              option  is mutually exclusive with the -D, -v and -r options. To
31              shutdown the daemon cleanly, just send it a SIGTERM or SIGINT.
32
33       -D     Do a dry run and don't delete anything. This option is  mutually
34              exclusive with the -d option.
35
36       -v     Be  verbose and print statistics. This option is mutually exclu‐
37              sive with the -d option.
38
39       -r     Clean thoroughly. This assumes that the Apache web server is not
40              running  (otherwise  you  may  get  garbage  in the cache). This
41              option is mutually exclusive with the -d option and implies  the
42              -t option.
43
44       -n     Be  nice.  This causes slower processing in favour of other pro‐
45              cesses. htcacheclean will sleep from time to time  so  that  (a)
46              the  disk  IO  will  be  delayed and (b) the kernel can schedule
47              other processes in the meantime.
48
49       -t     Delete all empty directories. By default only  cache  files  are
50              removed,  however  with  some configurations the large number of
51              directories created may require attention. If your configuration
52              requires  a  very large number of directories, to the point that
53              inode or file allocation table exhaustion may become  an  issue,
54              use of this option is advised.
55
56       -ppath Specify  path  as  the  root  directory  of the disk cache. This
57              should be the same value as specified with the CacheRoot  direc‐
58              tive.
59
60       -llimit
61              Specify  limit  as the total disk cache size limit. The value is
62              expressed in bytes by default (or attaching B  to  the  number).
63              Attach K for Kbytes or M for MBytes.
64
65       -i     Be intelligent and run only when there was a modification of the
66              disk cache. This option is only possible together  with  the  -d
67              option.

EXIT STATUS

71       htcacheclean returns a zero status ("true") if all operations were suc‐
72       cessful, 1 otherwise.
