Short recipes for different types of branch creation and removal

Set up local branches for all remote brances

git for-each-ref --format='%(refname:strip=3)' refs/remotes | grep -v master | xargs -L 1 git switch

Delete all local branches, but not master

git for-each-ref --format='%(refname:strip=2)' refs/heads | grep -v master | xargs git branch -d

Alternative: Delete only local branches that have been merged to master

git branch --merged master | grep -v master | xargs git branch -d

Delete all remote tracking branches except master

git for-each-ref --format='%(refname:strip=2)' refs/remotes | grep -v master | xargs git branch -rD origin

Delete all remote branches except master

git for-each-ref --format='%(refname:strip=2)' refs/remotes | grep -v master | xargs -L 1 git push -d origin 

Delete a subset of local branches

Assume they are arsting with bugs

git for-each-ref --format='%(refname:strip=2)' refs/heads/bugs | grep -v master | xargs git branch -d
