[olug] Unix Tip: FINDING A STRING

[Trent Melcher]

Note -H only works in the GNU grep.  Solaris and SCO don't have this option.
Don't know about HP-UX.
Also just checked BSD, some versions do, some don't.

Check your *nix Flavor to be certain.

A more direct version of the same thing would be:

find . -type f -exec grep -H "string" {} \;

Or if you don't want the lines, just the filenames

find . -type f -exec grep -q "strig" {} \; -print
