| <p><code>htcacheclean</code> is used to keep the size of |
| <code class="module"><a href="../mod/mod_disk_cache.html">mod_disk_cache</a></code>'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.</p> |

| <dl> |
| <dt><code>-d<var>interval</var></code></dt> |
| <dd>Daemonize and repeat cache cleaning every <var>interval</var> minutes. |
| This option is mutually exclusive with the <code>-D</code>, <code>-v</code> |
| and <code>-r</code> options. To shutdown the daemon cleanly, just send it |
| a <code>SIGTERM</code> or <code>SIGINT</code>.</dd> |
| |
| <dt><code>-D</code></dt> |
| <dd>Do a dry run and don't delete anything. This option is mutually |
| exclusive with the <code>-d</code> option.</dd> |
| |
| <dt><code>-v</code></dt> |
| <dd>Be verbose and print statistics. This option is mutually exclusive |
| with the <code>-d</code> option.</dd> |
| |
| <dt><code>-r</code></dt> |
| <dd>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 <code>-d</code> option.</dd> |
| |
| <dt><code>-n</code></dt> |
| <dd>Be nice. This causes slower processing in favour of other |
| processes. <code>htcacheclean</code> 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.</dd> |
| |
| <dt><code>-p<var>path</var></code></dt> |
| <dd>Specify <var>path</var> as the root directory of the disk cache. This |
| should be the same value as specified with the <code class="directive"><a href="../mod/mod_disk_cache.html#cacheroot">CacheRoot</a></code> directive.</dd> |
| |
| <dt><code>-l<var>limit</var></code></dt> |
| <dd>Specify <var>limit</var> as the total disk cache size limit. The value |
| is expressed in bytes by default (or attaching <code>B</code> to the |
| number). Attach <code>K</code> for Kbytes or <code>M</code> for |
| MBytes.</dd> |
| |
| <dt><code>-i</code></dt> |
| <dd>Be intelligent and run only when there was a modification of the disk |
| cache. This option is only possible together with the <code>-d</code> |
| option.</dd> |
