Chapter 37. Using Basic Unix Commands > Server Administration

Server Administration

Although everything that you've learned so far in this chapter is valid, it isn't necessarily completely functional. For example, you can't change the owner of a file you don't own. In most cases, that's fine, but for complete control over the machine, you should be able to do whatever you want.

The command that makes this possible is sudo. When sudo is placed in front of any other command, it enables you to execute the command as the root user. Root has complete control over everything on your system, so be careful when using the command; you could end up removing all the files from your computer.
