How to delete multiple git branches locally and remotely?

To delete multiple Git branches locally, you can use the following command in the terminal:

git branch -d branch1 branch2 branch3

This will delete the locally specified branches. If any branches have not been merged, you will need to use -D instead of -d to force the deletion.

To delete the same branches remotely, you can use:

git push origin --delete branch1 branch2 branch3

Make sure to replace "branch1", "branch2" and "branch3" with the actual names of your branches. This removes branches both locally and in the remote repository.
