If you've been working on any repo for an extended amount of time, you may have saved a million branches that have already been merged. It is time to clean all those old ones out.
The commands we'll be using.
# Removes references from branches that are no longer on the origin git remote prune origin
Note this next part will depend on your main branch's name. If you haven't yet, then you should rename
main. See below for how to.
# Lists all the branches that have been merged into main and remove them git branch --merged main | grep -v '^[ *]*main$' | xargs git branch -d
The last step is relatively easy. Combine it into your
.bashrc. I'm sure there's a Windows and Linux equivalent, but I'm using macOS.
alias cleanUpMyGit="git remote prune origin ; git branch --merged master | grep -v '^[ *]*master$' | xargs git branch -d"
Go ahead and restart your terminal, then try it out in a repo directory.
Afterward, you should see a list of the branches removed by the command. Happy Coding!
