    Command:

    git-symbolic-ref

    
    
    

    SYNOPSIS

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

    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>.
    
           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

           -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.
    
           -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. This was fine, and
           internally that is what still happens by default, but on platforms that
           do not have working symlinks, or that do not have the readlink(1)
           command, this was a bit cumbersome. On some platforms, ln -sf does not
           even work as advertised (horrors). Therefore symbolic links are now
           deprecated and symbolic refs 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.
