How to use git config --unset-all with a regex to remove many keys?

Question

In my git config I have many url. sections where I have been testing rewrite rules.

I want to unset them in bulk using something like:

git config --global --unset-all url.https://.insteadof

The git documentation says I can use a regex to match multiple values but I am struggling to format the command.

How to format the above command to match multiple urls and unset them all? Using wildcard syntax I would write something lile url.https://*

git config --unset-all doesn't accept wildcards or regexps. So the task must be split into a few commands: 1st, get full keys that correspond to a regex; 2nd, unset the keys.

To get the keys and verify these are exactly the keys you want to unset use the command:

git config --global --get-regexp '^url\.https://.+\.insteadof'

To unset all the keys:

git config --global --get-regexp --name-only '^url\.https://.+\.insteadof' |
    xargs -n1 git config --global --unset-al

Now repeat

git config --global --get-regexp '^url\.https://.+\.insteadof'

to check the keys were unset.

PS. Backup your ~/.gitconfig before experimenting.
