Thanks to both of you for your responses. I prefer the more traditional & 
perhaps readable methods so I'll use Dave's but Jakub's was interesting and on 
my train of thought in terms of output. Think I was starting at it for too 
long a time! Still, I've learned what $? etc. is :)

Because I'm a pain! I think it's just how I use both utilities; awk does the 
tidying and grep the finding. By breaking them up I've got both a full and tidy 
list of modes, as well as the best 1024 to do things with.

Thanks to both of you for the help :)
