Chapter 1: Overview of the Windows Command Line

---

Overview

The command line is built into the Microsoft Windows operating system and is accessed through the command shell window. Every version of Windows has had a built-in command line, used to run built-in commands, utilities, and scripts. Although the command line is powerful and versatile, some Windows administrators never use it. If you are happy using the graphical administration tools, you may be able to use them forever without ever having to do anything more than point and click.

For proficient Windows administrators, skilled support staff and committed power users, however, the Windows command line is inescapable. Knowing how to use the command line properly, including which command-line tools to use when and how to put the tools to work effectively, can mean the difference between smooth-running operations and frequent problems. And if you’re responsible for multiple domains or networks, learning the time-saving strategies that the command line offers is not only important, but essential, for sustaining day-to-day operations.

In this chapter, I’ll explain command line essentials, how to use built-in commands, how to run command-line utilities, and how to work with support and resource kit tools.

Real World

As you read this chapter, and the rest of the book, keep in mind that this book is written for Windows Server 2003 and Windows XP Professional. Techniques that you learn in this book can be used on both operating systems, unless otherwise noted. In some cases, you might be able to use the techniques discussed with other Windows operating systems, though the options or functions may vary. In any case, you should always test commands, options, and scripts before using them. The best way to do this is in a development or test environment where the systems with which you are working are isolated from the rest of the network.
