Command-line utilities provide some of the most powerful and useful features you'll find anywhere.

As you explore Windows you'll find that hundreds of utilities are available and all of them can be run within your Windows scripts.

In this appendix, we've selected the top utilities that you may want to use. You'll find a quick reference for commands as well as detailed entries on command usage and syntax. All examples show command-line and Windows script syntax.

ARP -s inet_addr eth_addr [if_addr]
