CMD

(from Command)

Starts a new instance of the Windows command interpreter (CMD.EXE).

CMD [/A | /U] [/Q] [/D] [/T:fg][/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF] [[/S] [/C | /K] string]

Where:

• /C - Executes the command specified by the string, then terminates.
• /K - Executes the command specified by the string and remains.
• /S - Changes the treatment of the specified string after /C or /K (does not preserve quotes).
• /Q - Disables ECHO (hides subsequent commands and the current directory, see ECHOECHO).
• /D - Disables running AutoRun commands from the registry.
• /A - Outputs internal commands to pipes or files in ANSI format.
• /U - Outputs internal commands to pipes or files in Unicode format.
• /T:fg - Sets text and background colors (see COLORCOLOR).
• /E:ON - Enables command extensions (recommended if they are disabled, enabled by default).
• /E:OFF - Disables command extensions (not recommended).
• /F:ON - Enables directory and file name completion characters.
• /F:OFF - Disables directory and file name completion characters (disabled by default).
• /V:ON - Enables delayed expansion of environment variables using ! as delimiter (example: !PATH!).
• /V:OF - Disables delayed environment expansion (disabled by default).
• string - Specifies the command or commands to execute. If the string contains spaces or special characters, quotes are required. For multiple commands, use && to join them (example: ECHO OFF && CLS).

Analogous options:

• /X - Similar to /E:ON.
• /Y - Similar to /E:OFF.
• /R - Similar to /C.

Examples:

1. Start a new instance of the command prompt by turning off ECHO and running the command ATTRIB +H C:\Omfg!!.txt, then exits (see ATTRIBATTRIB):

cmd /q /c "attrib +h C:\Omfg!!.txt"

 

2. Start a new instance of the command prompt by setting the text colors to blue and the background to white and running the CLS command, then remains (see CLSCLS):

cmd /t:f9 /k cls
