It is actually a set of MS-DOS command "coded" in the form of text file (for which the extension was changed).

One opened, the commands written in this file will be executed.

Prerequisites

  • Uncheck the "Hide file extensions of the type known in the advanced options of Windows Explorer.
  • Use a text editor that saves the file in plain text (not binary).

Create a blank batch file

  • This is the basis for creating all type of batch files:
  • Right click on the desktop -> New -> Text Document;
  • Open this file and rename it as .bat or .cmd

Some useful examples of MS-DOS commands

  • Ping www.nameofwebsite.com initiate pings on IP addresses or domain name.
  • Tracert www.nameofwebsite.com: Determines the route from your PC to remote IP addresses or domain name..

  • Echo TheTextOfyourchoice: Displays text on screen
  • Shutdown parameters:
    • r: Restart the system.
    • s: Turns off the system.
    • p: Turns off the computer power without the usual delay. (For Vista and Seven).
