Github Multiple Avatars

If you are like me with multiple avatars, foo and bar on the GitHub, and want to access GitHub with both those avatars from the same machine. Here is how I do it and her is you too could do it.

First I would create two differet keys to access each of those users.

ssh-keygen -b 4096 -C foo@gmail.com
ssh-keygen -t ecdsa -b 521 -C bar@hotmail.com

Second, I create two folders, foo-gh and bar-gh. I would usually create them in my home directory.

mdkir -p ~/foo-gh
mkdir -p ~/bar-gh

Third I create .gitconfig files in each of those folder, ~/foo-gh/.gitconfig.foo…

$ ~/foo-gh/.gitconfig.foo
[user]
email = foo@gmail.com
name = Foo Fighters

[github]
user = "foo"

[core]
sshCommand = "ssh -i ~/.ssh/id_rsa"

… and ~/bar-gh/.gitconfig.bar

$ ~/bar-gh/.gitconfig.bar
[user]
email = bar@hotmail.com
name = Bar Biters

[github]
user = "bar"

[core]
sshCommand = "ssh -i ~/.ssh/id_ecdsa"

Finally I create ~/.gitconfig

[includeIf "gitdir:~/foo-gh/"] # include for all .git projects under ~/foo-gh/
        path = ~/foo-gh/.gitconfig.foo

[includeIf "gitdir:~/bar/"] # include for all .git projects under ~/bar-gh/
        path = ~/bar/.gitconfig.bar

Now I could use all the foo’s repositories from ~/foo-gh and bar’s repositories from ~/bar-gh.
