From this Stack Overflow thread:
git ls-files --others --exclude-standard
git clean removes untracked files from the working tree. git clean -n (--dry-run) shows a preview of the effect, and git clean -f (--force) actually deletes them. Use -d to delete folders as well.
git merge --squash my-feature brings in changes from the my-feature branch onto the current branch, without committing them.
git tag --sort=-creatordate --list "v-dev-*" | head -n1
Only lists tags matching the v-dev-* pattern (e.g. v-dev-0.1.0). With -creatordate we sort the tags in descending creation date. head -n1 picks up the first line from that output.
git tag | grep "v-dev-*" | xargs -n1 -I{} git push origin :{}
