Well, as described on its own manual page, here's a program that's "trivial, but cute." hgrep runs a grep and highlights the string being searched for, to make it easier for us to find what we're looking for.

% hgrep perl ~/Mail/save
> and some of it wouldn't compile properly.  I wonder if
Subject: install script, for perl scripts
 perl itself is installed?
> run but dies with a read error because it isn't properly
> if I can get it installed properly on another machine I

And now we know why the output looked useless: because most of it is! Luckily, hgrep is just a frontend; it simply passes all its arguments to grep. So hgrep necessarily accepts all of grep's options, and I can just use the -w option to pare the output down to what I want:

% hgrep -w perl ~/Mail/save
Subject: install script, for perl scripts
 perl itself is installed?
