| git-symbolic-ref(1) |
| =================== |
| |
| NAME |
| ---- |
| git-symbolic-ref - Read and modify symbolic refs |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| 'git symbolic-ref' [-m <reason>] <name> <ref> |
| 'git symbolic-ref' [-q] [--short] <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>. |
| |
| 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. |
| |
| --short:: |
| When showing the value of <name> as a symbolic ref, try to shorten the |
| value, e.g. from `refs/heads/master` to `master`. |
| |
| -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. |
