If you're doing this, I'd suggest:
find . -name 'string' -exec grep -i fa {} /dev/null \;
... to cause the filenames to appear in the output.

Excellent suggestion, Paul. Thanks.

Re: Unix grep question
Try this:
ls -1 | xargs -i grep -l searchstring {}
Of course, replace searchstring with whatever you
are searching for. The option on ls is a one, not
the letter L. The option on grep is the letter L.

Re: Unix grep question
Hello, Could you post your command and the error message an I can help you with the solution On most of the Unix distributions you have the limits on the file named /usr/include/limits.h. I can'nt remember if USS have it. If you cann't defeat the limits ... then try with a small shellscript using awk (get_line() and close()) and reading the file names from an input file previously generated with the list of files to grep. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Unix grep question
Best to use grep along with find for this kind of thing.

Yes, but it will likewise fail on the OP's ARG_MAX problem. Also
will fail if any of the filenames contain metacharacters. One
wishes for the GNU find's -print0 option coupled with their xargs's
-0 option.
