GitHub Error: Key already in use

Question

I have created two GitHub accounts. One for my work user and one for my personal self. I needed to do catch up on some work and as such cloned my work repo onto my personal PC

Answer 1

This works for me,

1. Generate the SSH keys using ssh-keygen. Let's say the key is in ~/.ssh/id_rsa_foo
2. Now, $ cat ~/.ssh/id_rsa_foo.pub and paste it on your GitHub keys.
3. You can use GIT_SSH_COMMAND environment variable to achieve what you want.
   Do $ GIT_SSH_COMMAND='ssh -i ~/.ssh/id_rsa_foo' git push origin master. Check your Github repo for the magic. Cheers!
