Dos Commands

Internal & External commands

Two kinds of commands that can be run from the command prompt. There are the internal commands that are built into the command interpreter like (del) &(dir) . These commands can only be run from a command prompt (or by invoking the command interpreter in some other way). They are listed in the table below. There is also a large list of external commands that use an additional executable file that can be run from either the command prompt or the Start-Run line.

Details of the various commands are available in several places. In the Professional version of Windows XP there is a help file ntcmds.chm, which has details of all the commands and their many switches. The help file can be opened by entering (without the quotes) "hh ntcmds.chm" into Start-Run. It may or may not be in the Home Edition, depending on what setup you have. However, in both versions a list of many (but not all) of the commands available can be obtained by entering "help" (without quotes) into a command prompt. For more detail on a specific command, enter "help command-name" or "command-name /?" For example to get information on the command (xcopy), enter "help xcopy" or "xcopy /?”. Microsoft keeps moving things, but the last time I checked they had a command line reference at this link. commonly used commands
