How to Use Multiple Git Configs on One Computer

If you are like me and do open source contributions from an office laptop and your company uses some other git service then this blog is for you.

Using separate directory for repos

Let’s say we will create a directory based on our type of work.

  • Work
  • Personal

Create a global git config file .gitconfig

You should have a global gitconfig from where you will map your specific type of gitconfigs.

And that’s it .gitconfig

Create two specific gitconfig for two purposes

  • .gitconfig-work
  • .gitconfig-personal

Map those two gitconfigs with global gitconfig with directory

git config --global --add includeif.gitdir:/path/to/work/directory .gitconfig-work

git config --global --add includeif.gitdir:/path/to/personal/directory .gitconfig-personal

Specify information in the gitconfigs

[user]
 name = work_user
 email = work_email
[user]
 name = personal_user
 email = personal_email

Go to the directory and see your config list

$ cd ~/work
$ mkdir work-test-repo
$ cd work-test-repo
$ git init
		*Initialized empty Git repository in /Users/aniruddha/work/work-test-repo/.git/*
$ git config -l   
		*credential.helper=osxkeychain
		includeif.gitdir:~/personal/.path=~/.gitconfig-personal
		includeif.gitdir:~/work/.path=~/.gitconfig-work
		**user.name=working_me
		user.email = work@work.com**
		core.repositoryformatversion=0
		core.filemode=true
		core.bare=false
		core.logallrefupdates=true
		core.ignorecase=true
		core.precomposeunicode=true*          
$ cd ~/personal
$ mkdir personal-test-repo
$ git init
	*Initialized empty Git repository in /Users/aniruddha/personal/.git/*
$ git config -l
	*credential.helper=osxkeychain
	includeif.gitdir:~/personal/.path=~/.gitconfig-personal
	**user.name=me_personal
	user.email=personal@personal.com**
	includeif.gitdir:~/work/.path=~/.gitconfig-work
	core.repositoryformatversion=0
	core.filemode=true
	core.bare=false
	core.logallrefupdates=true
	core.ignorecase=true
	core.precomposeunicode=true*

Now you can see you have two types of gitconfigs according to your directory.
