<p>Many Git porcelainish commands take mixture of flags
|
|
(i.e. parameters that begin with a dash <em>-</em>) and parameters
|
|
meant for the underlying <em>git rev-list</em> command they use internally
|
|
and flags and parameters for the other commands they use
|
|
downstream of <em>git rev-list</em>. This command is used to
|
|
distinguish between them.</p>

reflog entry of the current branch. For example, if you are on

<dt class="hdlist1"><em>@{-<n>}</em>, e.g. <em>@{-1}</em></dt>

|
|
<p>The suffix <em>@{upstream}</em> to a branchname (short form <em><branchname>@{u}</em>)
|
|
refers to the branch that the branch specified by branchname is set to build on
|
|
top of (configured with <code>branch.<name>.remote</code> and
|
|
<code>branch.<name>.merge</code>). A missing branchname defaults to the
|
|
current one. These suffixes are also accepted when spelled in uppercase, and
|
|
they mean the same thing no matter the case.</p>

</dd>
|
|
<dt class="hdlist1"><em><branchname>@{push}</em>, e.g. <em>master@{push}</em>, <em>@{push}</em></dt>
|
|
<dd>
|
|
<p>The suffix <em>@{push}</em> reports the branch "where we would push to" if
|
|
<code>git push</code> were run while <code>branchname</code> was checked out (or the current
|
|
<code>HEAD</code> if no branchname is specified). Since our push destination is
|
|
in a remote repository, of course, we report the local tracking branch
|
|
that corresponds to that branch (i.e., something in <em>refs/remotes/</em>).</p>

dereferenced anymore (in which case, barf).

<dt class="hdlist1"><em>:/<text></em>, e.g. <em>:/fix nasty bug</em></dt>

<p>A colon, followed by a slash, followed by a text, names

a commit whose commit message matches the specified regular expression.
|

This name returns the youngest matching commit which is

reachable from any ref, including HEAD.
|
|
The regular expression can match any part of the
|
|
commit message. To match messages starting with a string, one can use
|
|
e.g. <em>:/^foo</em>. The special sequence <em>:/!</em> is reserved for modifiers to what
|
|
is matched. <em>:/!-foo</em> performs a negative match, while <em>:/!!foo</em> matches a

|
literal <em>!</em> character, followed by <em>foo</em>. Any other sequence beginning with

<em>:/!</em> is reserved for now.

<em>:path</em> (with an empty part before the colon)
|
|
is a special case of the syntax described next: content

recorded in the index at the given path.
|
|
A path starting with <em>./</em> or <em>../</em> is relative to the current working directory.
|
|
The given path will be converted to be relative to the working tree’s root directory.
|

This is most useful to address a blob or tree from a commit or tree that has

|
the same tree structure as the working tree.</p>

colon, followed by a path, names a blob object in the

index at the given path. A missing stage number (and the colon

|
that follows it) names a stage 0 entry. During a merge, stage

|
1 is the common ancestor, stage 2 is the target branch’s version
