SSH Tab completion!

So I was using stuble upon and I found a cool one. Adding tab completion to SSH/SCP!
The original code is at http://drawohara.com/post/6584031/life-changing-shell-function
But I propose a slightly different egrep line, which helps me at work (as our hostnames have numbers in them)
Basically, edit your .bash_profile or .bashrc files ( I prefer .bash_profile ), and add in the following lines:
SSH_COMPLETE=( $(cat ~/.ssh/known_hosts | \
sed -e 's/ .*//g' -e 's/,.*//g' | \
uniq | egrep -v "^([0-9]{1,3}.){4}$") )
complete -o default -W "${SSH_COMPLETE[*]}" ssh
complete -o default -W "${SSH_COMPLETE[*]}" scp
Once added, type source ~/.bash_profile (or ~/.bashrc)
This will parse the ~/.ssh/known_hosts file on login, and find any hostnames (but not IPs) and store them in a temporary variable. This variable is parsed to add tab completion to the ssh and scp commands.
To use, type ssh dan-[tab] and it will auto complete the domain (if it was previously listed in the known_hosts file!)
