Uh, sorry, Mark, but which of env/printenv/echo works depends on what
command line interpreter you're using, as well as what Unix you're
using. Just ask how to find the terminal type on a v6 system :-).

The ability to use your favorite CLI is a win. You have to expect that
things that change/print/otherwise-diddle the internal data structures
of the CLI will change as you change CLIs. For the most part, they
stay constant across different flavors of Unix if you stay with the
same CLI. Now, what you shouldn't ask is how the terminal type
information got imbedded into the CLI on Unix.
