Show which git tag you are on?

git describe is a porcelain command, which you should avoid:

Instead, I used:

git name-rev --tags --name-only $(git rev-parse HEAD)

Show all tags on current HEAD (or commit)

git tag --points-at HEAD

Edit

Jakub Narębski has more git-fu. The following much simpler command works perfectly:

git describe --tags

(Or without the --tags if you have checked out an annotated tag. My tag is lightweight, so I need the --tags.)

Original answer

git describe --exact-match --tags $(git log -n1 --pretty='%h')

Someone with more git-fu may have a more elegant solution...

This leverages the fact that git-log reports the log starting from what you've checked out. %h prints the abbreviated hash. Then git describe --exact-match --tags finds the tag (lightweight or annotated) that exactly matches that commit.

The $() syntax above assumes you're using bash or similar.

This worked for me git describe --tags --abbrev=0

Edit 2020: As mentioned by some of the comments below, this might, or might not work for you, so be careful!
