Getting latest tag on git repository

git-utils.sh

# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

# other examples
git describe --abbrev=0 --tags # gets tag from current branch
git describe --tags `git rev-list --tags --max-count=1` # gets tags across all branches, not just the current branch

# To delete remote tags (before deleting local tags) simply do:
git tag -l | xargs -n 1 git push --delete origin

# and then delete the local copies:
git tag | xargs git tag -d
