I use something similar for my projects,
alias testdemall='.for script in $(ls | grep '^[0-9]*_.*.sh'); do
echo "Executing script '$script'."
Got it from the MLL project, and use it for quite alot of lengthy builds with a lot of files.
What about the easter egg from apt XD, 'apt-get moo'? Quite a fun command to try if you are new to linux or an old time user.
