Command prompt commands are instructions used for specific tasks in operating systems that feature a command-line interface. While the term refers to commands for Windows 8, 7, Vista and XP, commands for Windows 98, 95 and MS-DOS are known as MS-DOS commands.
Some common command prompt commands, or CMD commands, include "append," "arp," "assoc," "tasklist" and "attrib." The "arp" command, which is available in all versions of Windows, displays or changes entries in the ARP cache. The "assoc" command, which is only available in Windows 8, 7, Vista and XP, displays a full list of file extensions and the particular programs that open each type. The command also changes file extensions and the programs associated with them. The "append" command, which is only available in MS-DOS and 32-bit versions of Windows operating systems, opens files from a different directory as if they were in the current directory.
The "attrib" command, which is compatible with versions of Windows as well as MS-DOS, changes the attributes of a single file or a directory. The "tasklist" command displays a list of programs currently running on a computer. It shows tasks that are hidden from Windows' Task Manager. The "taskkill" command stops processes that are currently running on the computer.
