Why don't you simply try?

So all is good.

But: if you want the official put on this for git, check out the <a href="http://www.kernel.org/pub/software/scm/git/docs/gitcli.html" rel="nofollow"><code>gitcli</code></a> man page. It states:

<blockquote>
 splitting short options to separate words (prefer git foo -a -b to git foo -ab, the latter may not even work)
</blockquote>

So your mileage may vary, and the separate form is preferred by the git team.

Yes.

Well-written Unix commands let you coalesce multiple single-letter options behind a single hyphen, as long as none of the options except the last one in the group can take an argument. Git is one of these well-written commands.

Many people who haven't spent much time in the Unix shell don't realize this, and unfortunately, sometimes those people end up writing command-line utilities that don't use the standard <code>getopt(3)</code> to parse their options, and end up writing their own parser that doesn't allow you to coalesce options in the standard way like this. So there are some poorly-written commands that don't allow that. Luckily, git is not one of those poorly-written commands.

I assume the poster is asking because he doesn't have access to Git, given that it would obviously been easier to try it than to post the question. To his credit, I actually made an effort to find the canonical answer in the Git documentation (without the aid of Google, mind you) and failed.

<pre><code>$ git commit -am "yay"
# On branch master
nothing to commit (working directory clean)
</code></pre>

Remember, Git is written by Linus Torvalds, creator of Linux. If anyone is going to strictly adhere to the <a href="http://www.gnu.org/prep/standards/html_node/Command_002dLine-Interfaces.html" rel="nofollow">POSIX guidelines</a>, it's him... You'll note that the double dash (<code>--</code>) to mark the end options and beginning of arguments is also part of the Git syntax:

<pre><code>git log -n 10 -- some/file.txt
</code></pre>

From the <a href="http://git-scm.com/docs/git-log" rel="nofollow">git log</a> man page:

<pre><code>[--] &lt;path&gt;…
 Show only commits that affect any of the specified paths. To prevent 
 confusion with options and branch names, paths may need to be prefixed
 with "-- " to separate them from options or refnames.
</code></pre>

Can <code>git commit -a -m "commit msg"</code> be shortened to <code>git commit -am "commit msg"</code> and work as expected?

Basically, can options be given as "short" switches and let the last switch accept an argument?

Can git switch options be shortened?

git commit -a -m "commit msg"可以缩写为git commit -am "commit msg"并按预期工作吗？基本上，选项是否可以作为“短”开关给出，并让最后一个开关接受参数？
