How to delete remote branches that have been merged with GIT

git branch -a --merged | \
grep -v master | \
grep -v develop | \
grep -v release | \
sed 's/remotes\/origin\//:/' | \
xargs -n 1 git push origin

This command will check all merged branch including remote ones. It’ll then remove any vbranch containing master, develop or release. Strips out remotes/origin and pass it to git push origin.

Let’s say, I created a branch that I called PFS-1, opened a PR and merged it, then the final command executed would be git push origin :PFS-1.
