Basics of Batch Scripting
Batch Scripting consists of a series of commands to be executed by the command-line interpreter, stored in a plain text file. It is not commonly used as a programming language and so it is not commonly practiced and is not trending but its control and dominance in the Windows environment can never be neglected. Almost every task and every action can be performed and executed by a simple sequence of commands typed on the Windows Command Prompt.
Batch Script execution
There are 2 ways to execute a batch script.
- Type the batch script in the command prompt.
- Write the code of script in a file and execute it through the command prompt.
Typing commands again and again on the terminal can be a very tedious task to do if we have a very lengthy code. So option 2 is generally preferred to create batch files.
