NAME

|
----
|
|
git-check-ref-format - Ensures that a reference name is well formed
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git check-ref-format' <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 under the `$GIT_DIR/refs/heads` directory, and
|
|
a tag is stored under the `$GIT_DIR/refs/tags` directory. git
|
|
imposes the following rules on how references are named:
|
|
|
|
. They can include slash `/` for hierarchical (directory)
|
|
grouping, but no slash-separated component can begin with a
|
|
dot `.`.
|
|
|
|
. They cannot have two consecutive dots `..` anywhere.
|
|
|
|
. They cannot have ASCII control characters (i.e. bytes whose
|
|
values are lower than \040, or \177 `DEL`), space, tilde `~`,
|
|
caret `{caret}`, colon `:`, question-mark `?`, asterisk `*`,
|
|
or open bracket `[` anywhere.
|
|
|
|
. They cannot end with a slash `/` nor a dot `.`.
|
|
|
|
. They cannot end with the sequence `.lock`.
|
|
|
|
. They cannot contain a sequence `@{`.
|
|
|
|
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 linkgit:git-rev-parse[1]):
|
|
|
|
. A double-dot `..` is often used as in `ref1..ref2`, and in some
|
|
contexts this notation means `{caret}ref1 ref2` (i.e. not in
|
|
`ref1` and in `ref2`).
|
|
|
|
. A tilde `~` and caret `{caret}` are used to introduce the postfix
|
|
'nth parent' and 'peel onion' operation.
|
|
|
|
. 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".
|
|
|
|
. at-open-brace `@{` is used as a notation to access a reflog entry.
|
|
|
|
With the `--branch` option, it expands a branch name shorthand and
|
|
prints the name of the branch the shorthand refers to.
|
|
|
|
EXAMPLE
|
|
-------
|
|
|
|
git check-ref-format --branch @{-1}::
|
|
|
|
Print the name of the previous branch.
