Cliff,

Yes, it's off-topic, but I see no reason to simply send people away for 
that reason when I have information that might be useful.

As to the "find" part being unnecessary, you don't know that. I assume the 
reason Kevin originally included the "find" in his attempt is that he 
wanted to grep in files (of the stipulated name patterns) in the current 
directory or anywhere beneath it. What you're suggesting will find only 
those files in the current directory.

It's also possible to use grep's (GNU grep's) -R option in combination with 
the "--include" argument to select files with the proper name pattern. In 
this case, this is probably the best way to go in terms of overhead and 
almost certainly will yield the best net performance.
