I'm not as familiar with the shell as a I should be.  How would I go 
about using a named pipe?  And what's the differences between that and a 
tmp file?

It's been suggested that if I want to make this really portable then a 
tmp file is actually the best way to go, so it's not off the list, just 
low on it.

and more trouble than its worth.

Thanks for the input and help.
