There are over 1500 commands on Linux. You might start with some of the 
basics, such as ps (process status), ls (similar to the DOS dir command), 
and man. Most Linux commands are documented by the man command and are 
referred as man pages. 
To start off with:
ps simply gives you a list of programs running from your login shell. 
ps ax gives you a list of everything running on your system.

ls simply lists the files in short form. ls -l produces a long listing. In 
both cases, files beginning with the dot (.) are not listed. ls -a is the 
same as ls, but dotfiles are listed. ls -al is a long list of all files. 

man ps - this gives you the man page for the ps command. 
man ls - gives you the manpage for ls. 

Server administration is more complex because you must know the 
configuration files and what things mean. This is where a good book comes 
in. Maybe the 2005 edition of the Linux Bible we looked at last night. 

The bottom line is that start with a live CD with a GUI front end. Start 
from there and play around. You really can't screw things up too much.
