Git: Delete all branches except for the master branch
It can be as simple as this alias in your terminal
alias gbr="git branch | grep -v "master" | xargs git branch -D"
In my case, I had multiple branches and when I ran the
gbr command, it showed the following result, deleting all three branches I had.
$ gbr Deleted branch 19EKofcx (was b849981). Deleted branch chA5sUqj (was 2198d89). Deleted branch rewrite (was 17a9dba).
