How to prevent git from using the global config?

Question

I have case where running some git related tests could generate failures if the user running them has some custom hooks installed inside his ~/.git-template/hooks folder.

Mainly I do want to find a way to run git commands in insolation, where git would skip using the default hooks and maybe even loading other global configs.

To ignore the system config file (/etc/gitconfig), you can set the environment variable GIT_CONFIG_NOSYSTEM to 1/true/yes before running your command.

e.g. GIT_CONFIG_NOSYSTEM=true git <command>
