gitconfig: locations of git configuration files

Question

How can I find/list the global and the users config files? I mean "Git-native functionality", not Linux commandos like find.

Answer 1

In this question a comment indicated how to know which file is related to --system, --global and --local.

In short you just use --edit to git config:

git config --system --edit
git config --global --edit
git config --local --edit

If you replace the environment-variable EDITOR with e.g. echo you can receive it in a variable, ie. you can use it programmatically:

t=`EDITOR=echo git config --system --edit`
echo $t

prints /etc/gitconfig in my case.
