git-symbolic-ref - Man Page
Read, modify and delete symbolic refs
- Store a reference by a name:
git symbolic-ref refs/name ref
- Store a reference by name, including a message with a reason for the update:
git symbolic-ref -m "message" refs/name refs/heads/branch_name
- Read a reference by name:
git symbolic-ref refs/name
- Delete a reference by name:
git symbolic-ref --delete refs/name
- For scripting, hide errors with
--shortto simplify ("refs/heads/X" prints as "X"):
git symbolic-ref --quiet --short refs/name
git symbolic-ref [-m <reason>] <name> <ref> git symbolic-ref [-q] [--short] [--no-recurse] <name> git symbolic-ref --delete [-q] <name>
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.
- -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.
When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master.
- --recurse, --no-recurse
When showing the value of <name> as a symbolic ref, if <name> refers to another symbolic ref, follow such a chain of symbolic refs until the result no longer points at a symbolic ref (--recurse, which is the default). --no-recurse stops after dereferencing only a single level of symbolic ref.
Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref.
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.
