What does "-N" do in grep included with FreeBSD?  My version
(FreeBSD 8) only has "-n".

I know of one tcgrep (by Tom Christiansen) ...

  http://www.perl.com/CPAN/authors/id/TOMC/scripts/tcgrep.gz


Then, there is ack ...

  http://search.cpan.org/dist/ack/ack


... may need to tinker with option to search non-Perl files (see -a
option).

Or, simply ...

  #!/bin/sh

  #  If your particular egrep is laced with potent PCRE, may use -P
  #  option (before "$@") to specify Perl regex.
  egrep -r $@ .
