Sometimes you want to write a bash script accessing the current git tag and its annotation. Here is how it can be done:
Accessing current git tag
Getting the current git tag is fairly easy:
git describe --tags
Getting the annotation of that tag
Getting the annotation is a bit more work. First we need to list all tags with their annotation (-n100 means git tag -l can show 100 lines of annotations). Then we use the tail command to strip of the first line (-n +2 means starting with the second line), because it contains the tag information.
git tag -l -n100 $(git describe --tags) | tail -n +3
