Use the Command Prompt's Online Help
Here's probably the most valuable lesson I can give when using the command line: remember how to get help. There are just too many commands, switches, and arguments that can be combined in literally countless ways, and as I mentioned, the command line insists that you get the typing just right.
Fortunately, it's not that hard to access a command utility's built-in help. All you have to do is type /? at the end of any command. For example, say you want to convert the file system on one of your partitions from FAT to NTFS, but you can't quite remember the syntax of the convert.exe utility. To get the exact syntax, type the following at the Command Prompt:
(And in case the printed page doesn't make this clear, there's a space between the t and the /.)
An online help tutorial then stampedes down your command environment. This help file should include all switches available and the proper syntax for each. If you're a Command Prompt junkie (I'm addressing both of you), you've used this help feature dozens of times and are probably not even bothering with this chapter.
