This will be my first reply to my first thread.
I'm using Puppy Linux on a USB memory stick. Don't care if it gets trashed so I'll try an ext3 to ext4 "upgrade."
What I have done with GREP is create some dummy files to search in. Never got it to work. Some (real) programmer friends of mine (you know, the engineers with degrees) said that they used it all the time. So it has been more like "magic" for me. I'll try it again.
I'll copy some old files and see what I can find. I'm a teacher and now I show kids how to do simple finds using MS Word search. If I can get GREP working I can see a LOT of us for it!!
