 331 <h2 id="_description">DESCRIPTION</h2>
 332 <div class="sectionbody">
 333 <div class="para"><p>With no arguments, existing branches are listed and the current branch will
 334 be highlighted with an asterisk.  Option <tt>-r</tt> causes the remote-tracking
 335 branches to be listed, and option <tt>-a</tt> shows both.</p></div>
 336 <div class="para"><p>With <tt>--contains</tt>, shows only the branches that contain the named commit
 337 (in other words, the branches whose tip commits are descendants of the
 338 named commit).  With <tt>--merged</tt>, only branches merged into the named
 339 commit (i.e. the branches whose tip commits are reachable from the named
 340 commit) will be listed.  With <tt>--no-merged</tt> only branches not merged into
 341 the named commit will be listed.  If the &lt;commit&gt; argument is missing it
 342 defaults to <em>HEAD</em> (i.e. the tip of the current branch).</p></div>
 343 <div class="para"><p>The command's second form creates a new branch head named &lt;branchname&gt;
 344 which points to the current <em>HEAD</em>, or &lt;start-point&gt; if given.</p></div>
 345 <div class="para"><p>Note that this will create the new branch, but it will not switch the
 346 working tree to it; use "git checkout &lt;newbranch&gt;" to switch to the
 347 new branch.</p></div>
 348 <div class="para"><p>When a local branch is started off a remote branch, git sets up the
 349 branch so that <em>git-pull</em> will appropriately merge from
 350 the remote branch. This behavior may be changed via the global
 351 <tt>branch.autosetupmerge</tt> configuration flag. That setting can be
 352 overridden by using the <tt>--track</tt> and <tt>--no-track</tt> options.</p></div>
 353 <div class="para"><p>With a <em>-m</em> or <em>-M</em> option, &lt;oldbranch&gt; will be renamed to &lt;newbranch&gt;.
 354 If &lt;oldbranch&gt; had a corresponding reflog, it is renamed to match
 355 &lt;newbranch&gt;, and a reflog entry is created to remember the branch
 356 renaming. If &lt;newbranch&gt; exists, -M must be used to force the rename
 357 to happen.</p></div>
 358 <div class="para"><p>With a <tt>-d</tt> or <tt>-D</tt> option, <tt>&lt;branchname&gt;</tt> will be deleted.  You may
 359 specify more than one branch for deletion.  If the branch currently
 360 has a reflog then the reflog will also be deleted.</p></div>
 361 <div class="para"><p>Use -r together with -d to delete remote-tracking branches. Note, that it
 362 only makes sense to delete remote-tracking branches if they no longer exist
 363 in the remote repository or if <em>git-fetch</em> was configured not to fetch
 364 them again. See also the <em>prune</em> subcommand of <a href="git-remote.html">git-remote(1)</a> for a
 365 way to clean up all obsolete remote-tracking branches.</p></div>
