Update 2016: with git 2.8 (March 2016), you can simply use:

git config --list --show-origin

And with Git 2.26 (Q1 2020), you can add a --show-scope option

git config --list --show-origin --show-scope

You will see which config is set where.
See "Where do the settings in my Git configuration come from?"

As Steven Vascellaro points out in the comments,

it will work with non-standard install locations. (i.e. Git Portable)

(like the latest PortableGit-2.14.2-64-bit.7z.exe, which can be uncompressed anywhere you want)

Original answer (2010)

From the docs:


For writing options: write to global ~/.gitconfig file rather than the repository .git/config.

Since you're using Git for Windows, it may not be clear what location this corresponds to. But if you look at etc/profile (in C:\Program Files\Git), you'll see:




(on Windows 7)

That means the file is in C:\Users\MyLogin\.gitconfig for Git in Windows 7.
