Thanks for the BusyBox hint, John.

I looked at your link and did not see one of my faves listed - whereis . What would you recommend as the easiest way to get whereis to run on my n810?

I went to tldp and downloaded many of the how-tos (they are available in pdf and other formats). I keep them on my n810 for quick ref.

Also recommend this book:
