       git-symbolic-ref - Read, modify and delete symbolic refs


       git symbolic-ref [-m <reason>] <name> <ref>
       git symbolic-ref [-q] [--short] <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

       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.

           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.
