GIT-CHECK-REF-FOR(1)		  Git Manual		  GIT-CHECK-REF-FOR(1)

NAME
       git-check-ref-format - Ensures that a reference name is well formed

SYNOPSIS
       git check-ref-format [--normalize]
	      [--[no-]allow-onelevel] [--refspec-pattern]
	      <refname>
       git check-ref-format --branch <branchname-shorthand>

DESCRIPTION
       Checks if a given refname is acceptable, and exits with a non-zero
       status if it is not.

       A reference is used in Git to specify branches and tags. A branch head
       is stored in the refs/heads hierarchy, while a tag is stored in the
       refs/tags hierarchy of the ref namespace (typically in
       $GIT_DIR/refs/heads and $GIT_DIR/refs/tags directories or, as entries
       in file $GIT_DIR/packed-refs if refs are packed by git gc).

       Git imposes the following rules on how references are named:

	1. They can include slash / for hierarchical (directory) grouping, but
	   no slash-separated component can begin with a dot .	or end with
	   the sequence .lock.

	2. They must contain at least one /. This enforces the presence of a
	   category like heads/, tags/ etc. but the actual names are not
	   restricted. If the --allow-onelevel option is used, this rule is
	   waived.

	3. They cannot have two consecutive dots ..  anywhere.

	4. They cannot have ASCII control characters (i.e. bytes whose values
	   are lower than \040, or \177 DEL), space, tilde ~, caret ^, or
	   colon : anywhere.

	5. They cannot have question-mark ?, asterisk *, or open bracket [
	   anywhere. See the --refspec-pattern option below for an exception
	   to this rule.

	6. They cannot begin or end with a slash / or contain multiple
	   consecutive slashes (see the --normalize option below for an
	   exception to this rule)

	7. They cannot end with a dot ..

	8. They cannot contain a sequence @{.

	9. They cannot be the single character @.

       10. They cannot contain a \.

       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 gitrevisions(7)):

	1. A double-dot ..  is often used as in ref1..ref2, and in some
	   contexts this notation means ^ref1 ref2 (i.e. not in ref1 and in
	   ref2).

	2. A tilde ~ and caret ^ are used to introduce the postfix nth parent
	   and peel onion operation.

	3. A colon : is used as in srcref:dstref to mean "use srcref’s value
	   and store it in dstref" in fetch and push operations. It may also
	   be used to select a specific object such as with git cat-file: "git
	   cat-file blob v1.3.3:refs.c".

	4. at-open-brace @{ is used as a notation to access a reflog entry.

       With the --branch option, it expands the “previous branch syntax”
       @{-n}. For example, @{-1} 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.

OPTIONS
       --[no-]allow-onelevel
	   Controls whether one-level refnames are accepted (i.e., refnames
	   that do not contain multiple /-separated components). The default
	   is --no-allow-onelevel.

       --refspec-pattern
	   Interpret <refname> as a reference name pattern for a refspec (as
	   used with remote repositories). If this option is enabled,
	   <refname> is allowed to contain a single * in place of a one full
	   pathname component (e.g., foo/*/bar but not foo/bar*).

       --normalize
	   Normalize refname by removing any leading slash (/) 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. (--print is a
	   deprecated way to spell --normalize.)

EXAMPLES
       ·   Print the name of the previous branch:

	       $ git check-ref-format --branch @{-1}

       ·   Determine the reference name to use for a new branch:

	       $ ref=$(git check-ref-format --normalize "refs/heads/$newbranch") ||
	       die "we do not like '$newbranch' as a branch name."
