How to Create a Batch Program:

Google+ Pinterest LinkedIn Tumblr +

As said earlier, batch programs can be written using any of the text editors such as notepad,

wordpad and so on, but notepad is the most often used text editor in such cases. Like any other

programing languages, lets start our first program with the ‘Hello World’ program.

1. Open up a notepad and type the following.

@echo off

Echo Hello World

pause

2. Save the file with any name you wish, but make sure that you save the file extension with .bat, in

this case I am saving this file as ‘first.bat’.

3. When you save the batch file, then the icon becomes like the below icon,

In Windows XP, the Batch file icon looks like above, where as in Windows Vista the Icon looks like the

below image,

4. Just double click to execute the batch file that you have created now. And the output looks like,

5. You are done!

Let me explain what does the above given program does,

‘echo’ is the command used to print text on the screen, so whatever that follows the echo

command will be displayed on the output screen. This command is just like the ‘printf’ statement in the C

language.

When you type the echo command alone, then it will tell you whether the ‘echo is ON’ or ‘echo is OFF’.

It’s always recommended to turn the echo off, else it will display the prompts like (C:\>) and so on. In

order to avoid the prompts being displayed, the echo is turned off by using the command “@echo off” or

simply by using the “echo off”.

“Echo Hello World” will display the “Hello World” on the output screen, and the pause command is used

to wait for the user interaction, whether to proceed further or not. If the pause is not used, then the batch

will terminate immediately after displaying the “Hello World”.

Internal and External Commands

There are two types of commands that we can run from a command prompt, and they were,

1. Internal commands

2. External commands.

Internal Commands

Internal commands are nothing but the built-in commands that are shipped along with the

operating system, for example, echo, cls, del, dir were few of the well known internal commands.

External Commands

External commands are the commands that are often created while installing a new application

and these commands mostly have no use except calling that application and support files. Few external

commands can only be executed in the ‘Run’ dialog box (start  Run), but not on the command prompt,

and those commands include ‘firefox’. The ‘firefox’ command can be executed only from the run line, that

too if the firefox application is installed on that machine and it won’t work on the command prompt.

Likewise the ‘firefox’ there are various other external commands such as the “PsTools” which includes

commands like, PsExec, PsFile, PsGetSid, PsInfo, PsKill, PsList, PsLoggedOn and so on.
