Thanks, this is even closer. z is being set, but it outputs something to
the screen which does go away after a few seconds. Any idea how to
stop it from doing that? I wonder if there's some code I could output
that turned off display output, did this command, then turn it back on
again?
I couldn't use this in an alias as it would disrupt the screen each
time I ran ssh or scp. But it does get the necessary info.
Thomas, what you suggest, it's similar to the people who suggest symlinking
some known place to the /tmp folder and then setting that in the environment.
Here's a link to the superuser.com post about this:

You're right, it works a most of the time. Where it fails is if I log
in a second time from a different computer. I was just looking to see
if I could fix that.
