[NBLUG/talk] Syntax of scp

[Todd Cary]

Mitch -

My goal is to tar ( -czvf ) /home /etc/passwd and /etc/shadow, scp it to 
my temporary computer that has a new Fedora Core 1 OS installed.  Then I 
want to untar the file and have the temporary computer handle the work 
while I rebuild my production system.

Never having done this before, I am not sure if the relative paths will 
be restored when I untar the file.
