Batch Script Tutorial

Batch Scripts are stored in simple text files containing lines with commands that get executed in sequence, one after the other. Scripting is a way by which one can alleviate this necessity by automating these command sequences in order to make ones life at the shell easier and more productive. This tutorial discusses the basic functionalities of Batch Script along with relevant examples for easy understanding.

What is Batch Scripting?

Batch scripting is a powerful tool for automating tasks on Windows operating systems. By writing scripts in plain text files with a ".bat" or ".cmd" extension, you can execute multiple commands without manual intervention, saving time and reducing the risk of errors.

Batch scripting consists of a series of commands to be executed by the command-line interpreter, stored in a plain text file (batch file). Developers can automate various tasks such as creating files, deleting files, renaming files, and much more on servers and local machines using batch files. It is especially useful for repetitive tasks, like setting up new projects or automating routine tasks.
