No--good question. 'sudo' is a cool innovation in Darwin, the  
modified BSD unix system that is the basic of Mac OS X. Apple (I  
think) added it to give command line users an easy way to execute one  
command as the root user, also called the 'super user'. So 'sudo' is  
short for 'super user do', or 'Do the following command as the super  
user.' In essence, it gives one absolute, invincible power for one  
brief moment, if one knows the root password. I pronounce it like  
'pseudo', but I've heard other people say 'soo-doo'. Anyway, with  
that background, check out my current favorite cartoon on the internet:

Have a good weekend everyone.
