Stupid linux grep question

I installed linux on my pda and i need to know how to get grep to search the entire root system for a phrase okuwlan. I know how to pipe commands and what not just not how to get it to search EVERY thing. Thanks

I believe
grep -r "pattern" /
should do the trick

thats the problem i dont have r and an option this is what i get.. this is using busybox v1.0

Usage: grep [-ihHnqvs] PATTERN [FILEs...]

Thanks

Does find work?

find / -type f -exec grep "patern" {} \;

Also keep in mind there are usually more than 1 grep on systems...

Do a 'man -k grep' and boggle :)

On mine, it came up with:

Quote:

I do have the find command however its just Usage: find [PATH...] [EXPRESSION] so Sir dices idea doesnt apear to work. This is all running on a ipaq pda pretty cool but sucks cuz its so stripped down.

Well, why don't you get the original sources and compile them? grep alone shouldn't take up too much extra space on the PDA and if you can afford a meg or two, I don't think it should be too hard. http://www.gnu.org/software/grep/

EDIT: I just checked, the compressed grep sources are ~600kb, so the binary should be less than a meg.
