NAME
git-symbolic-ref - Read, modify and delete symbolic refs
SYNOPSIS
git symbolic-ref\n [-m <reason>] <name> <ref>
\ngit symbolic-ref\n [-q] [--short] [--no-recurse] <name>
\ngit symbolic-ref\n --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 content is ref: refs/heads/master.
OPTIONS
-d, --delete
-q, --quiet
--short
--recurse, --no-recurse
-m
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.
