   Sorry for the confusion there :-)  The -a and -x options are meant 
for cp(1).  The -a (--archive) option in cp(1) for linux (which I am 
fairly certain is the gnu version) is essentially an easy way to safely 
do -dpR automatically.  So effectively -a (--archive) preserves links, 
tries to preserve permissions, and also does a recursive copy.  The -x 
(--one-file-system) option in cp(1) for linux says that if you have 
multiple file systems mounted on top of / and you do a `cp -ax / 
/mnt/copy/of/root/.` it should only copy the directory stubs for the 
mounts instead of the mounts themselves.  I have found both of these 
options to be extremely useful at times.

   Again, sorry for the misunderstanding and not providing enough 
information upfront.  In linux date(1) is the gnu version of date, which 
means you can do the following `date --date 'Jan 22 2002'` and it would 
output the following:

Tue Jan 22 00:00:00 CST 2002

   Or I could do a `date --date '2 days ago'` and it would output:

Sun Jan 20 00:46:30 CST 2002

   Again, this option might not be the most useful thing in the world 
but I know that I have used it many times at home and at work to make 
scripts less complicated.

   Thank you for the response and let me know if you need any further 
information to be able to tell what the options I was refering to for 
cp(1) and date(1) actually do.
