README.md

What

When you have multiple accounts or multiple ssh keys for git, and you want separation and not to deal with git config --local user.email "blablabla",

How

You need to directories on your home for example

  ~/Workspace/work
  ~/Workspace/personal

Then Put each git-config somwehere, I choose ~/dotfiles

  ~/dotfiles/.gitconfig-work
  ~/dotfiles/.gitconfig-personal

Then your main ~/.gitconfig would just use:

[includeIf "gitdir:~/Workspace/work/"]
   path = ~/dotfiles/.gitconfig-work
[includeIf "gitdir:~/Workspace/personal/"]
   path = ~/dotfiles/.gitconfig-personal

That tells git to load the proper config file when a directory is accessed, like, when you go to

  cd ~/Workspace/work

Git will load the .gitconfig-work automatically...

Gotchas

The config files here are mine, so adapt them to your tase..

Cheers
