Managing multiple identities with git and ssh

If you have multiple git repositories, you should create an ~/.ssh/config file to reflect your "identities", here is mine:


# Default GitHub user
Host github.com
 HostName github.com
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/personalPrivateKey

# Work user account
Host supercode.com
 HostName supercode.com
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/my_workplace_companyPrivateKey
