How to remove every local branch except the current branch?

git branch | grep -v "^*" | xargs git branch -D

To remove every local branch except the currently checked out branch use git branch | grep -v "^*" | xargs git branch -D. The command has three parts, git branch lists all the local branches, grep -v "^*" selects every branch except the current one and with xargs git branch -D these branches are deleted.

Be careful, this command removes the main branch as well.

To do a dry run and see what branches would be removed use git branch | grep -v "^*".

git branch

* ab-test

  feature-branch

  main

  test-branch

git branch | grep -v "^*" | xargs git branch -D
