Batch Script

The commands in a batch file are executed by a special interface or shell. These commands may include "goto," "for," "call," "echo," "setlocal," etc., and may make use of decision and loop constructs. A batch script can be created using any text editor such as Notepad or WordPad, and must be saved only in plain text format.

A batch file can be run easily by clicking on it or by typing its name in a command line interpreter. A batch script can also be run with arguments. The following are some of the commonly used commands in a batch script:

• Echo — To display some text on the screen
• Call — To run a batch script from within another script
• Goto — To transfer control or execution sequence to a label or subroutine
• If — To test a condition
• Pause — To wait until a key is pressed
• Rem — To include a comment line in the script
• Setlocal — To start a local environment
• Endlocal — To terminate a local environment
• Shift — To parse the command line arguments in the script
• Start — To run a script with a default application
