<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 and implies
|
|
the <code>-t</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>-t</code></dt>
|
|
<dd>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.</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>
