How can I use regular expressions now in OSX? I used to use an OSAX in OS9. Grep wants to check a file. How do I send a string to check through a shell script? I thought I had figured this out months ago and now I can’t find my example that I saved in a “Safe Place” 
I’m speculating, having not actually done this yet 
There is an OSAX called mgrep.
As well you can pass arguments to a shell script:
do shell script " grep " & variable_with_word_in_it & " " & variable_with_filename & "
I may have too many "'s in there…

Satimage scripting addition does regular expressions nicely in Mac OS X. It’s a free download from http://www.osaxen.com/smile.html
