<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>Updates files in the working tree to match the version in the index
or the specified tree. If no paths are given, <em>git checkout</em> will
also update <code>HEAD</code> to set the specified branch as the current
branch.</p></div>
<div class="dlist"><dl>
<dt class="hdlist1">
<em>git checkout</em> &lt;branch&gt;
</dt>
<dd>
<p>
To prepare for working on &lt;branch&gt;, switch to it by updating
the index and the files in the working tree, and by pointing
HEAD at the branch. Local modifications to the files in the
working tree are kept, so that they can be committed to the
&lt;branch&gt;.
</p>
<div class="paragraph"><p>If &lt;branch&gt; is not found but there does exist a tracking branch in
exactly one remote (call it &lt;remote&gt;) with a matching name, treat as
equivalent to</p></div>
<div class="listingblock">
<div class="content">
<pre><code>$ git checkout -b &lt;branch&gt; --track &lt;remote&gt;/&lt;branch&gt;</code></pre>
</div></div>
<div class="paragraph"><p>You could omit &lt;branch&gt;, in which case the command degenerates to
"check out the current branch", which is a glorified no-op with
rather expensive side-effects to show only the tracking information,
if exists, for the current branch.</p></div>
</dd>
<dt class="hdlist1">
<em>git checkout</em> -b|-B &lt;new_branch&gt; [&lt;start point&gt;]
</dt>
<dd>
<p>
Specifying <code>-b</code> causes a new branch to be created as if
<a href="git-branch.html">git-branch(1)</a> were called and then checked out. In
this case you can use the <code>--track</code> or <code>--no-track</code> options,
which will be passed to <em>git branch</em>. As a convenience,
<code>--track</code> without <code>-b</code> implies branch creation; see the
description of <code>--track</code> below.
</p>
<div class="paragraph"><p>If <code>-B</code> is given, &lt;new_branch&gt; is created if it doesn&#8217;t exist; otherwise, it
is reset. This is the transactional equivalent of</p></div>
<div class="listingblock">
<div class="content">
<pre><code>$ git branch -f &lt;branch&gt; [&lt;start point&gt;]
$ git checkout &lt;branch&gt;</code></pre>
</div></div>
<div class="paragraph"><p>that is to say, the branch is not reset/created unless "git checkout" is
successful.</p></div>
</dd>
<dt class="hdlist1">
<em>git checkout</em> --detach [&lt;branch&gt;]
</dt>
<dt class="hdlist1">
<em>git checkout</em> [--detach] &lt;commit&gt;
</dt>
<dd>
<p>
Prepare to work on top of &lt;commit&gt;, by detaching HEAD at it
(see "DETACHED HEAD" section), and updating the index and the
files in the working tree. Local modifications to the files
in the working tree are kept, so that the resulting working
tree will be the state recorded in the commit plus the local
modifications.
</p>
<div class="paragraph"><p>When the &lt;commit&gt; argument is a branch name, the <code>--detach</code> option can
be used to detach HEAD at the tip of the branch (<code>git checkout
&lt;branch&gt;</code> would check out that branch without detaching HEAD).</p></div>
<div class="paragraph"><p>Omitting &lt;branch&gt; detaches HEAD at the tip of the current branch.</p></div>
</dd>
<dt class="hdlist1">
<em>git checkout</em> [&lt;tree-ish&gt;] [--] &lt;pathspec&gt;&#8230;
</dt>
<dd>
<p>
Overwrite paths in the working tree by replacing with the
contents in the index or in the &lt;tree-ish&gt; (most often a
commit). When a &lt;tree-ish&gt; is given, the paths that
match the &lt;pathspec&gt; are updated both in the index and in
the working tree.
</p>
<div class="paragraph"><p>The index may contain unmerged entries because of a previous failed merge.
By default, if you try to check out such an entry from the index, the
checkout operation will fail and nothing will be checked out.
Using <code>-f</code> will ignore these unmerged entries. The contents from a
specific side of the merge can be checked out of the index by
using <code>--ours</code> or <code>--theirs</code>. With <code>-m</code>, changes made to the working tree
file can be discarded to re-create the original conflicted merge result.</p></div>
</dd>
<dt class="hdlist1">
<em>git checkout</em> (-p|--patch) [&lt;tree-ish&gt;] [--] [&lt;pathspec&gt;&#8230;]
</dt>
<dd>
<p>
This is similar to the "check out paths to the working tree
from either the index or from a tree-ish" mode described
above, but lets you use the interactive interface to show
the "diff" output and choose which hunks to use in the
result. See below for the description of <code>--patch</code> option.

Create a new <em>orphan</em> branch, named &lt;new_branch&gt;, started from

new branch will have no parents and it will be the root of a new
history totally disconnected from all the other branches and

<div class="paragraph"><p>If you want to start a disconnected history that records a set of paths
that is totally different from the one of &lt;start_point&gt;, then you should
clear the index and the working tree right after creating the orphan

When switching branches,
if you have local modifications to one or more files that
are different between the current branch and the branch to
which you are switching, the command refuses to switch
branches in order to preserve your modifications in context.
However, with this option, a three-way merge between the current
branch, your working tree contents, and the new branch
is done, and you will be on the new branch.
