276</div>
277<h2>DESCRIPTION</h2>
278<div class="sectionbody">
Junio C Hamanoe58607f2007-01-17 23:27:45279<p>Usually you would want to use <a href="git-push.html">git-push(1)</a> which is a
280higher level wrapper of this command instead.</p>
Junio C Hamano1a4e8412005-12-27 08:17:23281<p>Invokes <em>git-receive-pack</em> on a possibly remote repository, and
282updates it from the current repository, sending named refs.</p>
283</div>
284<h2>OPTIONS</h2>
285<div class="sectionbody">
286<dl>
287<dt>
288--exec=&lt;git-receive-pack&gt;
289</dt>
290<dd>
291<p>
292 Path to the <em>git-receive-pack</em> program on the remote
293 end. Sometimes useful when pushing to a remote
294 repository over ssh, and you do not have the program in
295 a directory on the default $PATH.
296</p>
297</dd>
298<dt>
299--all
300</dt>
301<dd>
302<p>
303 Instead of explicitly specifying which refs to update,
304 update all refs that locally exist.
305</p>
306</dd>
307<dt>
308--force
309</dt>
310<dd>
311<p>
312 Usually, the command refuses to update a remote ref that
313 is not an ancestor of the local ref used to overwrite it.
314 This flag disables the check. What this means is that
315 the remote repository can lose commits; use it with
316 care.
317</p>
318</dd>
319<dt>
320&lt;host&gt;
321</dt>
322<dd>
323<p>
324 A remote host to house the repository. When this
325 part is specified, <em>git-receive-pack</em> is invoked via
326 ssh.

328</dd>

347<h2>Specifying the Refs</h2>
348<div class="sectionbody">
349<p>There are three ways to specify which refs to update on the
350remote end.</p>
Junio C Hamano341071d2006-06-04 07:24:48351<p>With <em>--all</em> flag, all refs that exist locally are transferred to
Junio C Hamano1a4e8412005-12-27 08:17:23352the remote side. You cannot specify any <em>&lt;ref&gt;</em> if you use
353this flag.</p>
354<p>Without <em>--all</em> and without any <em>&lt;ref&gt;</em>, the refs that exist
355both on the local side and on the remote side are updated.</p>
356<p>When one or more <em>&lt;ref&gt;</em> are specified explicitly, it can be either a
357single pattern, or a pair of such pattern separated by a colon
358":" (this means that a ref name cannot have a colon in it). A
359single pattern <em>&lt;name&gt;</em> is just a shorthand for <em>&lt;name&gt;:&lt;name&gt;</em>.</p>
360<p>Each pattern pair consists of the source side (before the colon)
361and the destination side (after the colon). The ref to be
362pushed is determined by finding a match that matches the source
363side, and where it is pushed is determined by using the
364destination side.</p>
365<ul>
366<li>
367<p>
368It is an error if &lt;src&gt; does not match exactly one of the
369 local refs.
370</p>
371</li>
372<li>
373<p>
374It is an error if &lt;dst&gt; matches more than one remote refs.
375</p>
376</li>
377<li>
378<p>
379If &lt;dst&gt; does not match any remote ref, either
380</p>
381<ul>
382<li>
383<p>
384it has to start with "refs/"; &lt;dst&gt; is used as the
385 destination literally in this case.
386</p>
387</li>
388<li>
389<p>
390&lt;src&gt; == &lt;dst&gt; and the ref that matched the &lt;src&gt; must not
391 exist in the set of remote refs; the ref matched &lt;src&gt;
392 locally is used as the name of the destination.
393</p>
394</li>
395</ul>
396</li>
397</ul>
398<p>Without <em>--force</em>, the &lt;src&gt; ref is stored at the remote only if
399&lt;dst&gt; does not exist, or &lt;dst&gt; is a proper subset (i.e. an
400ancestor) of &lt;src&gt;. This check, known as "fast forward check",
401is performed in order to avoid accidentally overwriting the
402remote ref and lose other peoples' commits from there.</p>
403<p>With <em>--force</em>, the fast forward check is disabled for all refs.</p>
404<p>Optionally, a &lt;ref&gt; parameter can be prefixed with a plus <em>+</em> sign
405to disable the fast-forward check only on that ref.</p>
