I need to write a simple cgi script that takes a string from the user and searches for it using grep. If I grep only one file, it works fine. But if I make the script grep -r, the cgi script does not display the results. However, running the script w/ grep -r from the command line, I get the results. 
if (open (GREP, "-|")) {
    print <GREP>;
} else {
    exec ("grep", "-r", $string, ".") || die "Error exec'ing command",
+ "\n";
}
close (GREP);
