How to delete a branch without error message if the branch does not exist?

Question

I would like to include a command to delete the local Git branch in the script, and I don't want any error message to be displayed if the branch does not exist. At the same time, I also don’t want a status code indicating that the Git command has failed.

In the following example:

git branch -D foo

If a branch exists, it is deleted, and the return status of the command is 0, which indicates success. If I run the same script again, the branch no longer exists, so the command does not work, prints

error: branch 'foo' not found.

and the return status of the Git command is> 0, which indicates an error.

Is there a way to silence a team, so anyway, was there a branch in the first place? Ideally, it will not display an error message, nor does it indicate a failure through a non-zero return status.
