git-symbolic-ref(1) |
|
=================== |
|
|
|
NAME |
|
---- |
|
git-symbolic-ref - Read and modify symbolic refs |
|
|
|
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. |
