ssh with multiple github accounts
Suppose you maintain several github accounts (say personal and work accounts) and have separate ssh keys for the accounts. You can use host aliases in your ssh config file to simplify your ssh/github interactions. Include entries in along these lines in ~/.ssh/config:
# Personal account Host personal.github.com User git IdentityFile ~/.ssh/personal_key HostName github.com # Work account Host work.github.com User git IdentityFile ~/.ssh/work_key HostName github.com
A work project using the above might have something like this in its .git/config file.
url = ssh://work.github.com/user_name/work_project.git
A personal project would instead use something like
url = ssh://personal.github.com/user_name/personal_project.git
The host alias in the url implicitly selects the the appropriate ssh key to use.
