branch head is stored in the &lt;code&gt;refs/heads&lt;/code&gt; hierarchy, while
a tag is stored in the &lt;code&gt;refs/tags&lt;/code&gt; hierarchy of the ref namespace
(typically in &lt;code&gt;$GIT_DIR/refs/heads&lt;/code&gt; and &lt;code&gt;$GIT_DIR/refs/tags&lt;/code&gt;
directories or, as entries in file &lt;code&gt;$GIT_DIR/packed-refs&lt;/code&gt;
if refs are packed by &lt;code&gt;git gc&lt;/code&gt;).&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;Git imposes the following rules on how references are named:&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;olist arabic&quot;&gt;&lt;ol class=&quot;arabic&quot;&gt;
&lt;li&gt;
&lt;p&gt;
They can include slash &lt;code&gt;/&lt;/code&gt; for hierarchical (directory)
  grouping, but no slash-separated component can begin with a
  dot &lt;code&gt;.&lt;/code&gt; or end with the sequence &lt;code&gt;.lock&lt;/code&gt;.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They must contain at least one &lt;code&gt;/&lt;/code&gt;. This enforces the presence of a
  category like &lt;code&gt;heads/&lt;/code&gt;, &lt;code&gt;tags/&lt;/code&gt; etc. but the actual names are not
  restricted.  If the &lt;code&gt;--allow-onelevel&lt;/code&gt; option is used, this rule
  is waived.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot have two consecutive dots &lt;code&gt;..&lt;/code&gt; anywhere.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot have ASCII control characters (i.e. bytes whose
  values are lower than \040, or \177 &lt;code&gt;DEL&lt;/code&gt;), space, tilde &lt;code&gt;~&lt;/code&gt;,
  caret &lt;code&gt;^&lt;/code&gt;, or colon &lt;code&gt;:&lt;/code&gt; anywhere.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot have question-mark &lt;code&gt;?&lt;/code&gt;, asterisk &lt;code&gt;*&lt;/code&gt;, or open
  bracket &lt;code&gt;[&lt;/code&gt; anywhere.  See the &lt;code&gt;--refspec-pattern&lt;/code&gt; option below for
  an exception to this rule.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot begin or end with a slash &lt;code&gt;/&lt;/code&gt; or contain multiple
  consecutive slashes (see the &lt;code&gt;--normalize&lt;/code&gt; option below for an
  exception to this rule)
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot end with a dot &lt;code&gt;.&lt;/code&gt;.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot contain a sequence &lt;code&gt;@{&lt;/code&gt;.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
They cannot contain a &lt;code&gt;\&lt;/code&gt;.
&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;These rules make it easy for shell script based tools to parse
reference names, pathname expansion by the shell when a reference name is used
unquoted (by mistake), and also avoids ambiguities in certain
reference name expressions (see &lt;a href=&quot;gitrevisions.html&quot;&gt;gitrevisions(7)&lt;/a&gt;):&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;olist arabic&quot;&gt;&lt;ol class=&quot;arabic&quot;&gt;
&lt;li&gt;
&lt;p&gt;
A double-dot &lt;code&gt;..&lt;/code&gt; is often used as in &lt;code&gt;ref1..ref2&lt;/code&gt;, and in some
  contexts this notation means &lt;code&gt;^ref1 ref2&lt;/code&gt; (i.e. not in
  &lt;code&gt;ref1&lt;/code&gt; and in &lt;code&gt;ref2&lt;/code&gt;).
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
A tilde &lt;code&gt;~&lt;/code&gt; and caret &lt;code&gt;^&lt;/code&gt; are used to introduce the postfix
  &lt;em&gt;nth parent&lt;/em&gt; and &lt;em&gt;peel onion&lt;/em&gt; operation.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
A colon &lt;code&gt;:&lt;/code&gt; is used as in &lt;code&gt;srcref:dstref&lt;/code&gt; to mean &quot;use srcref&amp;#8217;s
  value and store it in dstref&quot; in fetch and push operations.
  It may also be used to select a specific object such as with
  &lt;em&gt;git cat-file&lt;/em&gt;: &quot;git cat-file blob v1.3.3:refs.c&quot;.
&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
at-open-brace &lt;code&gt;@{&lt;/code&gt; is used as a notation to access a reflog entry.
&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;With the &lt;code&gt;--branch&lt;/code&gt; option, it expands the &amp;#8220;previous branch syntax&amp;#8221;
&lt;code&gt;@{-n}&lt;/code&gt;.  For example, &lt;code&gt;@{-1}&lt;/code&gt; is a way to refer the last branch you
were on.  This option should be used by porcelains to accept this
syntax anywhere a branch name is expected, so they can act as if you
typed the branch name.&lt;/p&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div class=&quot;sect1&quot;&gt;
&lt;h2 id=&quot;_options&quot;&gt;OPTIONS&lt;/h2&gt;
&lt;div class=&quot;sectionbody&quot;&gt;
&lt;div class=&quot;dlist&quot;&gt;&lt;dl&gt;
&lt;dt class=&quot;hdlist1&quot;&gt;
--[no-]allow-onelevel
&lt;/dt&gt;
&lt;dd&gt;
&lt;p&gt;
        Controls whether one-level refnames are accepted (i.e.,
        refnames that do not contain multiple &lt;code&gt;/&lt;/code&gt;-separated
        components).  The default is &lt;code&gt;--no-allow-onelevel&lt;/code&gt;.
&lt;/p&gt;
&lt;/dd&gt;
&lt;dt class=&quot;hdlist1&quot;&gt;
--refspec-pattern
&lt;/dt&gt;
&lt;dd&gt;
&lt;p&gt;
        Interpret &amp;lt;refname&amp;gt; as a reference name pattern for a refspec
        (as used with remote repositories).  If this option is
        enabled, &amp;lt;refname&amp;gt; is allowed to contain a single &lt;code&gt;*&lt;/code&gt;
        in place of a one full pathname component (e.g.,
        &lt;code&gt;foo/*/bar&lt;/code&gt; but not &lt;code&gt;foo/bar*&lt;/code&gt;).
&lt;/p&gt;
&lt;/dd&gt;
&lt;dt class=&quot;hdlist1&quot;&gt;
--normalize
&lt;/dt&gt;
&lt;dd&gt;
&lt;p&gt;
        Normalize &lt;em&gt;refname&lt;/em&gt; by removing any leading slash (&lt;code&gt;/&lt;/code&gt;)
        characters and collapsing runs of adjacent slashes between
        name components into a single slash.  Iff the normalized
        refname is valid then print it to standard output and exit
        with a status of 0.  (&lt;code&gt;--print&lt;/code&gt; is a deprecated way to spell
        &lt;code&gt;--normalize&lt;/code&gt;.)
&lt;/p&gt;
&lt;/dd&gt;
&lt;/dl&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div class=&quot;sect1&quot;&gt;
&lt;h2 id=&quot;_examples&quot;&gt;EXAMPLES&lt;/h2&gt;
&lt;div class=&quot;sectionbody&quot;&gt;
&lt;div class=&quot;ulist&quot;&gt;&lt;ul&gt;
&lt;li&gt;
&lt;p&gt;
Print the name of the previous branch:
&lt;/p&gt;
&lt;div class=&quot;listingblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;$ git check-ref-format --branch @{-1}&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;
Determine the reference name to use for a new branch:
&lt;/p&gt;
&lt;div class=&quot;listingblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;$ ref=$(git check-ref-format --normalize &quot;refs/heads/$newbranch&quot;) ||
die &quot;we do not like '$newbranch' as a branch name.&quot;&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div class=&quot;sect1&quot;&gt;
&lt;h2 id=&quot;_git&quot;&gt;GIT&lt;/h2&gt;
&lt;div class=&quot;sectionbody&quot;&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;Part of the &lt;a href=&quot;git.html&quot;&gt;git(1)&lt;/a&gt; suite&lt;/p&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
