1329<div class="paragraph"><p>This cache is meant to speed up commands that involve determining
1330untracked files such as <code>git status</code>.</p></div>
1331<div class="paragraph"><p>This feature works by recording the mtime of the working tree
1332directories and then omitting reading directories and stat calls
1333against files in those directories whose mtime hasn&#8217;t changed. For
1334this to work the underlying operating system and file system must
1335change the <code>st_mtime</code> field of directories if files in the directory
1336are added, modified or deleted.</p></div>
1337<div class="paragraph"><p>You can test whether the filesystem supports that with the
1338<code>--test-untracked-cache</code> option. The <code>--untracked-cache</code> option used
1339to implicitly perform that test in older versions of Git, but that&#8217;s
1340no longer the case.</p></div>
1341<div class="paragraph"><p>If you want to enable (or disable) this feature, it is easier to use
1342the <code>core.untrackedCache</code> configuration variable (see
1343<a href="git-config.html">git-config(1)</a>) than using the <code>--untracked-cache</code> option to
1344<code>git update-index</code> in each repository, especially if you want to do so
1345across all repositories you use, because you can set the configuration
1346variable to <code>true</code> (or <code>false</code>) in your <code>$HOME/.gitconfig</code> just once
1347and have it affect all repositories you touch.</p></div>
1348<div class="paragraph"><p>When the <code>core.untrackedCache</code> configuration variable is changed, the
1349untracked cache is added to or removed from the index the next time a
1350command reads the index; while when <code>--[no-|force-]untracked-cache</code>
