"man grep" on my linux box shows:
-r, --recursive
Read all files under each directory, recursively; this is
equivalent to the -d recurse
option.
change it to:
$cmdstr = "grep -r -i $searchstr *";
In all honesty though, you might want to use an ereg_replace() on
$searchstr before doing that, so that special shell characters can't get
through.
Interesting take on searching...
