Yep. You're right. I tested it, and the '&' causes the process to
detach from the parent and the 'exec' loses its intended behavior. He
could have left off the 'exec' on the 'quartz-wm' line and accomplished
the same thing. Sorry for distributing incorrect information.

That's what 'exec' does. Runs something in replacement to the current
script. So the second 'exec' never runs.
Well, it works for Mr. Summers, so _that's_ not true. Bash is strange,
though, and what it's presumably doing is looking at the '&' at the
end of
the line and ignoring the exec. (I'm told that Bash will actually give
an
error message for exec, if, for example, the format of the file being
exec'ed isn't executable.) But that's non-standard, and you shouldn't
be
doing it if you're intending to use other Unices in the future.
