How do I get all refs that point to a commit in git?

Is there any way to get a list of refs (including tags, branches, and remotes) that point to a particular commit in git?

git for-each-ref --format='%(refname)' \
    --exclude='refs/remotes/*/HEAD' --points-at=<commit> \
    'refs/heads/**' 'refs/remotes/**' 'refs/tags/**'

The --format overrides the default three-column output so that you only get the refname for each line.

Using only pipes. Outputs the identical SHA of the two branches if they are the same, fails with no output and exit code 1 otherwise.

git rev-parse A B |\
 uniq |\
 sed -n -e '${1p}' -e '2q 1'
  • rev-parse the 2+ branches
  • uniq only unique lines
  • ${1p} if last line and first line, print
  • 2q 1 else quit with exit code 1
    may be GNU specific. Try q if it doesn't work.

Human-readable format

For the last commit (ie, HEAD):

git log -n1 --oneline --decorate

Or to specify a particular commit:

git log -n1 --oneline --decorate fd88

gives:

fd88175 (HEAD -> master, tag: head, origin/master) Add diff-highlight and icdiff

To only get the tags/refs/remotes, pass this through sed:

$ git log -n1 --oneline --decorate | sed 's/.*(\(.*\)).*/\1/'

HEAD -> master, tag: head, origin/master

For bonus points, add an alias for this:

decorations = "!git log -n1 --oneline --decorate $1 | sed 's/.*(\\(.*\\)).*/\\1/' #"

git show-ref | grep $(git rev-parse HEAD) shows all refs that point to HEAD, the currently checked out commit.

git show-ref shows all refs in your git repo.

git show-ref | grep "SHA goes here" shows all refs that point to the SHA of a commit.
