Set a custom name as default to initialize your git repos
Let's assume that you would like to set name main as default name for your main branches in git.
If you have git >=2.28 installed the it is pretty easy:
git config --global init.defaultBranch main
In git versions <2.28 you have to create a template to use a different name:
mkdir -p ~/.config/git/template echo 'ref: refs/heads/main' > ~/.config/git/template/HEAD
