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

    '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`.

    --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.

    -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.
