Git Question

Get last git tag from a remote repo without cloning

How to get last tag from a (non checked-out) remote repo?

On my local copy I use


git describe --abbrev=0 --tags

But I cannot use
with remote storage

Answer Source

Use git ls-remote --tags <repository>

For example, if we want to know what the latest tag that Git is at we would do

git ls-remote --tags git://github.com/git/git.git

That returns a long list with all the tags in alphabetical order, as shown below (truncated for sanity's sake). The last line tells us the latest tag is v1.8.0-rc0.

Keep in mind that tags can be any kind of string so, as pointed out by Christopher Gervais in his answer, git ls-remote sorts tags alphabetically. Unfortunately git ls-remote does not have a --sort option (like, for example git for-each-ref), so your best option is to use native sort.

More recent versions of sort support the -V or --version-sort flag to do a natural sort of (version) numbers within text.

So to sort them naturally, your command would look like this:

git ls-remote --tags git://github.com/git/git.git | sort -t '/' -k 3 -V

Please take a look at (and upvote) Christopher Gervais's answer below if you need more/other greping options.
