Setup multiple Github accounts

multiple_github.md

Personal notes on working towards two different Github-accounts on the same machine.

Prerequisite:

One default ssh-key already exists: ~/.ssh/id_rsa

Generate a named ssh-key:

ssh-keygen -t rsa -C "my@email.com" -f "id_rsa_my_user"

Copy the public ssh_key to the Github-account:

pbcopy < ~/.ssh/id_rsa_my_user.pub

Add key to ssh-agent:

ssh-add ~/.ssh/id_rsa_my_user

Update ~/.ssh/config file:

Host github.com-my_user (An identifier for this Github account. Used it local .git-config to locate repo.)
HostName github.com User git IdentityFile ~/.ssh/id_rsa_my_user

Reference Github-repo by using the Host from ssh config:

git clone git@github.com-my_user:github-username/repo_name.git
