• Type the name of the command followed by /?. For example,
dir /?
• Type help followed by the name of the command. For
example,
help dir
For help with network-related commands, precede your help
request with net. For example, type net view /? or net help view for
information about the Net View command. (With the Net
commands, "net help command" provides more detailed help than
"net command /?")
You can also type help with no arguments to get a list of the
internal commands and system utilities provided with Windows
2000.
Editing the Command Line

When working at a command prompt, you often enter the same
command several times, or enter several similar commands. If you
make a mistake when typing a command line, you don't want to
retype the whole thing - you just need to fix the part that was
wrong. Windows 2000 includes a feature that recalls previous
commands and lets you edit them on the current command line.
Table 1 shows the editing keys and what they do.
