whereis grep
grep: /usr/5bin/grep /usr/bin/grep /usr/man/man1/grep.1v
/usr/5bin/grep also does not work.

Pipe not working with /usr/bin/grep. Why is that?
Notice...
print `/usr/bin/dig -x $ip | grep PTR`;
works, but:
print `/usr/bin/dig -x $ip | /usr/bin/grep PTR`;
does not.
Another alternative:
$results = join("", grep(/PTR/, `/usr/bin/dig -x $ip`));
