git - How do I remove deleted branch names from autocomplete?

Question

I used git branch -d myBranch to delete a branch. However, when I am on master and try to checkout a new branch with git checkout, myBranch still appears in the tab-autocomplete.

How do I remove the name myBranch from tab-autocomplete for git checkout?

Answer 1

git fetch --prune --all

Posting this as its own answer since it's a one-line fix, but if you vote be sure to vote for @twalberg's answer above.

@twalberg's suggestion to git branch -a led me on the right track; my coworker suggested git fetch --prune --all to prune all the dead branches from all the remotes, which is useful when working with lots of devs with lots of forks.
