How can I specify custom global gitconfig path?

Question

I\'m in a bit of a bind with Git. I\'m trying to execute git commit but I need to be able to swtich between ~/.gitconfig1 and ~/

Answer 1

I found a way to execute this - it wasn't elegant but it did work - and so far seems to be the only way to get this to work.

Git uses the HOME path to determine where .gitconfig is. I was able to perform something like this:

/home/marco/.silly/.gitconfig
/home/marco/.stupid/.gitconfig
/home/marco/.gitconfig

And when executing Git Commit (which is the only command that requires the .gitconfig) I overrode the home path.

HOME=/home/marco/.silly/ git commit -m "silly configuration"

You can then use alias to do this easily

alias sillygit="HOME=/home/marco/.silly/ git"
sillygit commit -m "silly stuff"
