# Get tags ordered correctly, and take the last one.
last="$(git tag --sort=v:refname | tail -n1)"

if [ -z "$last" ]; then
   echo "No last tag found"

If this script is executable and included in your PATH, you will be able to run this like git next-tag.

The version increment defaults to 'patch', but can pass 'major', 'minor', or 'patch', for example: git next-tag minor
