Using multiple github accounts with ssh keys

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

  1. Generate ssh key pairs for accounts and add them to GitHub accounts.

will automatically exchange ssh keys with remote server, allowing automatic future password-less access to the remote location from current location. edit as needed if remote location doesn't run sshd on default port.
#!/bin/bash
printf "enter username@ip-address: " ; read UIP ; ssh $UIP "mkdir .ssh 2>/dev/null ; echo $(cat $HOME/.ssh/id_rsa.pub) >>.ssh/authorized_keys ; chmod 700 .ssh ; chmod 600 .ssh/authorized_keys" ; echo "hostname=$(ssh $UIP hostname)"

encode image to base64 text string using native openssl package in osx. encoding with this method is more widely-available than the regular base64 package, because it doesn't first require installing xcode or building gnu coreutils from source.
