# 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: | |
