264git-commit-tree(1) Manual Page

266<h2>NAME</h2>
267<div class="sectionbody">
268<p>git-commit-tree -
269 Creates a new commit object
270</p>
271</div>
272</div>
273<h2>SYNOPSIS</h2>
274<div class="sectionbody">
275<p><em>git-commit-tree</em> &lt;tree&gt; [-p &lt;parent commit&gt;]* &lt; changelog</p>
276</div>
277<h2>DESCRIPTION</h2>
278<div class="sectionbody">
279<p>Creates a new commit object based on the provided tree object and
280emits the new commit object id on stdout. If no parent is given then
281it is considered to be an initial tree.</p>
282<p>A commit object usually has 1 parent (a commit after a change) or up
283to 16 parents. More than one parent represents a merge of branches
284that led to them.</p>
285<p>While a tree represents a particular directory state of a working
286directory, a commit represents that state in "time", and explains how
287to get there.</p>
288<p>Normally a commit would identify a new "HEAD" state, and while git
289doesn't care where you save the note about that state, in practice we
290tend to just write the result to the file that is pointed at by
291<tt>.git/HEAD</tt>, so that we can always see what the last committed
292state was.</p>
293</div>
294<h2>OPTIONS</h2>
295<div class="sectionbody">
296<dl>
297<dt>

305<dt>
306-p &lt;parent commit&gt;

308<dd>

310 Each <em>-p</em> indicates the id of a parent commit object.

312</dd>
313</dl>
314</div>
315<h2>Commit Information</h2>
316<div class="sectionbody">
317<p>A commit encapsulates:</p>
318<ul>
319<li>
320<p>
321all parent object ids
322</p>
323</li>
324<li>
325<p>
326author name, email and date
327</p>
328</li>
329<li>
330<p>
331committer name and email and the commit time.
332</p>
333</li>
334</ul>
335<p>If not provided, "git-commit-tree" uses your name, hostname and domain to
336provide author and committer info. This can be overridden by
337either <tt>.git/config</tt> file, or using the following environment variables.</p>

Junio C Hamano235a91e2006-01-07 01:13:58[diff] [blame]347<p>In <tt>.git/config</tt> file, the following items are used for GIT_AUTHOR_NAME and
348GIT_AUTHOR_EMAIL:</p>

354</div></div>
355<p>A commit comment is read from stdin (max 999 chars). If a changelog
356entry is not provided via "&lt;" redirection, "git-commit-tree" will just wait
357for one to be entered and terminated with ^D.</p>
