Nifty Bash Complete for SSH known_hosts

Just came across this today... Really useful, since 90% of my job requires SSHing off to remote hosts...

From drawohara:

Stick this in your ~/.bashrc

SSH_COMPLETE=( $(cat ~/.ssh/known_hosts | \
cut -f 1 -d ‘ ’ | \
sed -e s/,.*//g | \
uniq | \
egrep -v [0123456789]) )
complete -o default -W "${SSH_COMPLETE[*]}" ssh

This does a lookup for all the hosts in your ~/.ssh/known_hosts file, as a source for the autocompletion.
