One quick note for the unwary. The program is /bin/test. [ is a link to
that program.

I haven't checked really recently, but a small change in your script can
cause you a problem:

if [ "$TEST" = "yes" ]

will work.

if [ "$TEST" = "yes"]

will not.

I believe it's related to the way /bin/test parses its arguments.
