Teach symbolic-ref to delete symrefs by adding the -d/--delete option to git-symbolic-ref. Both proper and dangling symrefs are deleted by this option, but other refs - or anything else that is not a symref - is not. The symref deletion is performed by first verifying that we are given a proper symref, and then invoking delete_ref() on it with the REF_NODEREF flag.

NAME
|
|
----
|
|
git-symbolic-ref - Read, modify and delete symbolic refs
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git symbolic-ref' [-m <reason>] <name> <ref>
|
|
'git symbolic-ref' [-q] [--short] <name>
|
|
'git symbolic-ref' --delete [-q] <name>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Given one argument, reads which branch head the given symbolic
|
|
ref refers to and outputs its path, relative to the `.git/`
|
|
directory. Typically you would give `HEAD` as the <name>
|
|
argument to see which branch your working tree is on.
|
|
|
|
Given two arguments, creates or updates a symbolic ref <name> to
|
|
point at the given branch <ref>.
|
|
|
|
Given `--delete` and an additional argument, deletes the given
|
|
symbolic ref.
|
|
|
|
A symbolic ref is a regular file that stores a string that
|
|
begins with `ref: refs/`. For example, your `.git/HEAD` is
|
|
a regular file whose contents is `ref: refs/heads/master`.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
-d::
|
|
--delete::
|
|
Delete the symbolic ref <name>.
|
|
|
|
-q::
|
|
--quiet::
|
|
Do not issue an error message if the <name> is not a
|
|
symbolic ref but a detached HEAD; instead exit with
|
|
non-zero status silently.
|
|
|
|
--short::
|
|
When showing the value of <name> as a symbolic ref, try to shorten the
|
|
value, e.g. from `refs/heads/master` to `master`.
|
|
|
|
-m::
|
|
Update the reflog for <name> with <reason>. This is valid only
|
|
when creating or updating a symbolic ref.
|
|
|
|
NOTES
|
|
-----
|
|
In the past, `.git/HEAD` was a symbolic link pointing at
|
|
`refs/heads/master`. When we wanted to switch to another branch,
|
|
we did `ln -sf refs/heads/newbranch .git/HEAD`, and when we wanted
|
|
to find out which branch we are on, we did `readlink .git/HEAD`.
|
|
But symbolic links are not entirely portable, so they are now
|
|
deprecated and symbolic refs (as described above) are used by
|
|
default.
|
|
|
|
'git symbolic-ref' will exit with status 0 if the contents of the
|
|
symbolic ref were printed correctly, with status 1 if the requested
|
|
name is not a symbolic ref, or 128 if another error occurs.
