<h1>Maintenance</h1>

<h2>File System Check</h2>

<p>File system check verifies integrity. Finds corrupt objects.</p>

<pre><code>git fsck
</code></pre>

<p>Find orphaned objects that would be cleaned by prune</p>

<pre><code>git fsck --orphaned
</code></pre>

<h2>Prune</h2>

<p>Prune is a command that optimizes your repository by removing commits that are not orphaned.</p>

<pre><code>git prune
</code></pre>

<p>or to see what is orphaned, but not actually touch them:</p>

<pre><code>git prune --dry-run
</code></pre>

<p>or</p>

<pre><code>git prune -n
</code></pre>

<h2>Garbage Collect</h2>

<p>GC compacts old loose commits into pack files and <code>prune</code>s orphan commits. It is a superset of the <code>prune</code> command and is more commonly run than <code>prune</code>.</p>

<pre><code>git gc
</code></pre>

<p>or to compress and optimize for space and speed</p>

<pre><code>git gc --aggressive
</code></pre>
