Alright... . is a lot easier to type than :, so thanks.
Yep, I'm working on regular expressions... I can write simple ones at
the moment. Do you know of a place that has exercises to test knowledge,
because I think the best way to learn would be to practice and actually
do it.

several things I've never seen before though. Could you explain those
portions in more detail?
Specifically, I've never seen the -F switch to ls. Secondly, in:
chown kedwardk.kedwardk ed
Is there a difference between . and : in that? Would this have been
equivalent?
chown kedwardk:kedwardk ed
I think they are equivalent. I have a habit of using ".", perhaps
dating to my days with HPUX and ksh.
In the chmod, you did 2777... what does the 2 do that 777 doesn't?
Then, in the drwxrwsrwx, what does the s mean?
The 2 is the set guid bit for the directory. It is what does the
magic. 777 is very open. I didn't test whether I could close
down that hole. I suggest you experiment to see how much openness
is still neede.
I suppose my shell skills need a little working.
Thanks :).
Bash is a powerful language. With all the commands at
its disposal it becomes very powerful. But if there is one
thing I would recommend that everyone learn, it is regular
expressions. The grep man page is a good place to start.
