Use multiple Git SSH identities on a single computer

You can do a bit more, even: https://rya.nc/multi-github-accts.html

    Host *.github.com
        IdentityFile ~/.ssh/%h_id_rsa
        IdentitiesOnly yes
        HostKeyAlias github.com
        ProxyCommand nc github.com 22

The `ProxyCommand` hack makes a global `ControlMaster auto` still work with a `%C` based `ControlPath`, but using `Hostname github.com` should work when using something like `%n_%p_%r`.

Why not just use %n in the pattern (hostname as passed on the CLI rather than evaluated in the config) and then `Hostname github.com` inside the `Host` block instead of the latter two commands?

I think you may have replied while I was editing to suggest that.

What's this github subdomain format? Is this a real url you're matching or syntax for something else like your username / org name?

It's a fake subdomain used to select the key.
