Thanks to everyone for their help on this.  I'm stilll learning how
scripts and the syntax works...
Brian's suggestion:
find /tmp -type f |xargs fgrep -l cat |xargs fgrep -l dog
was the simplest for me to understand, even if it wasn't the most
efficient.  I promise to spend some time learning about shell scripts,
and I appreciate the explanations with the examples.

Thanks again,

grep is fine for simple use; I use it almost every day.

The minute I find myself piping to awk or building a line with more than one pipe in it, I stop myself and ask "Wouldn't this be easier with Perl?"

And of course the answer always is "yes".

I don't mean to discourage anyone from learning awk or shell scripting in general - it's good to know this stuff. But when your goal is to get something done efficiently and quickly, Perl is often a much better choice.

If you already know a bit about awk and grep, Perl is easy to learn -
you don't have to be expert to get a lot of mileage out of your knowledge. Take a peek at http://aplawrence.com/Unixart/loveperl.html for a gentle introduction.
