I'm really looking forward to this course!  I'll probably think of a
few commands I'd like clarifying - I'll let you know, Carla.

I'm a lot clearer now about Cron.  Thanks for that.

Presumably these should begin '05 01' and not '01 05'.

Should the dow numbers in the first of these read '6,0', or have I
misunderstood something?

Are you saying that you can list a single name (e.g. 'sat') but not
more than one?

Anyway, thanks for the first lesson in what promises to be a very
useful and interesting course.  I didn't know users could have their
own crontabs until now.
