Multi (file)source SSH host tab-completion

complete -W "$( { awk '/^Host / { print $2 }' ~/.ssh/config | egrep -v '\*|,' echo $( grep '^ssh ' .bash_history | sort -u | sed 's/^ssh //' ) while IFS=' ,' read host t; do echo $host; done < ~/.ssh/known_hosts ;} )" ssh

This is a multi-sourced hostname tab completion command you can put in your .bashrc (or your .bash_profile on a MAC). This will not only your .ssh/config, it will parse ALL of the following files for hostnames: .ssh/config .ssh/known_hosts .bash_history (I realize this could be prettied up by defining and calling the function, instead of implicitly referencing it, but this was more breif)

Sample Output

[user@host ~]$ ssh 10.160.<TAB>
