This works on my local machine

git ls-remote --tags | grep -o 'refs/tags/[0-9]*\.[0-9]*' | sort -r | head -1 | grep -o '[^\/]*$

but not in my jenkins build server which is running from docker, it doesn't have the rights and I can't seem to fix that.

Is there an alternative for ls-remote which would give me exactly the same output, but then for my local git repository?

Or, is there a silver bullet solution for getting the LATEST tag from my local repo, looking from the tip of the branch and then backwards? I have been struggling with git tag | head -1 and all kinds of alternatives but nothing gives me the latest tag searching back from the tip of the branch....

It looks like you are trying to compare version numbers.

If you are interested in "the tag with the highest version number in my repo" :

git tag --sort=v:refname | tail -1

if your version tags have a pattern to distinguish them from other tags :

git tag --sort=v:refname --list "v[0-9]*" | tail -1

note that the filter is a glob pattern, not a regexp :

v[0-9]* in the example above means : v followed by any char in [0-9] followed by anything else (*)

This will work if you have all tags locally, so run git fetch --tags before that to have an up to date list.

If you want "the tag with the highest version number in the history of my current branch" :

git tag --sort=v:refname --merged=HEAD | tail -1

If you want "the tag closest to my current commit" :

git describe --tags --abbrev=0

CodePudding user response：

git describe is a native way, considering

With --abbrev set to 0, the command can be used to find the closest tagname without any suffix
