Batch file programming examples pdf

In this tutorial, you will learn about batch file commands and how they are used in batch file scripting or programming.

As discussed in the previous tutorial, a batch file is an unformatted text file or script file which contains multiple batch file commands or instructions to achieve a certain task. It has extension of .bat or .cmd .

Batch file commands: Windows/DOS

For the ease of learning, we have listed all the batch file commands with relevant examples and explanations below. Please click on the commands to know the details.

List of batch file commands

Note: Batch file commands are not case sensitive

ASSOC

The batch command ASSOC associates a file extension with a file type, or list all associations.

Example

@echo OFF ASSOC | find ".txt" pause

Output

.txt = textfile

As shown in above output, it displays the file association for .txt extension.

If only ASSOC is written and executed, it will display all the file associations for every extension, instead of just .txt extension.

ATTRIB

The batch command ATTRIB is used to display the file attributes or set an attribute to a file in the working directory.

Example

Now let us suppose we have a file note.txt in our working directory. We will display its file attributes and then make it hidden and read only by adding 'ah' and 'r' attributes to it. And finally, we will remove some attributes we added as well.

@echo OFF :: To display attribute of note.txt ATTRIB note.txt :: To make it read only by adding 'r' ATTRIB +r note.txt ATTRIB note.txt :: To make it hidden by adding 'ah' ATTRIB +ah note.txt ATTRIB note.txt :: To remove attribute read only ATTRIB -r note.txt ATTRIB note.txt

Output

A note.txt A R note.txt A R AH note.txt A AH note.txt

Here in this output, A means Archived, R means Read only and AH means Hidden file.

CD

The batch command CD helps in navigating through different directories and changing directories or displaying current directory.

Example

@echo OFF :: CD without any parameters displays the current working directory CD :: Changing to the parent directory one level up CD.. CD :: Changing the path to Programs CD\Programs CD pause

The batch command CHKDSK is used for checking error in the disk.

Since the list of commands is so much more, we have sliced the list and shown few here.

Now that we have a list of batch file commands, we can also view details of their syntax and functionalities in following way:

@echo OFF :: Just type help and the command you want to know about HELP copy 

Now this will display details of the copy command.

As you can see, it HELP COPY displays all the details about COPY command.
