TIL: Clean up all branches except master (or another other rule you want)

git-cleanup

git branch | grep -v master | xargs -n 1 git branch -D


git brach list branches

grep -v is a filter

xargs -n 1 pass in the arguments 

git branch -D is the command.

This takes advantage of the pipe operator in *nix



Other versions

git branch --merged -> good for cleanup.

git branch --no-merged
