[Tfug] find | grep pipe question

[Charles R. Kiss]

Is there a find|grep pipe that will 'find' the numerous directories I 
have containing abook.mab files then grep out the terms containing the 
'@' symbol output them into a text file so that I can import them into 
my address book.

Or how else do I import the abook.mabs that I have collected over the 
years?? 

I normally just do separate find and grep operations to find old email 
addresses and I thought someone else might have a better idea.

TIA
