Recently, I had some tasks at work that required me to write a lot of batch files.
Here are some things about batch files that I either learned or re-discovered in the process:
Don’t use blanks when assigning values to variables
This works:
Commands marked. are Internal commands only available within the CMD shell. All other commands (not marked with.) are external commands. External commands may be used under the CMD shell, PowerShell, or directly from START-RUN. See also: A categorized list of Windows CMD commands. Microsoft Help pages: Windows Commands 8.1-10 / Windows Server 2012-2019. DOS Cheat Sheet - This Docstoc.com reference lists and explains batch file commands, command syntax, NTFS and more. MS-DOS - This Word document explains important concepts for running MS-DOS. DOS to FreeBSD Cheat Sheet - This cheat sheet offers a list of commands available on Microsoft's DOS and Windows platforms and the equivalent command. To create the batch file, open your favorite text editor. For most Windows 10 users that will likely be Notepad. Type 'notepad' into the Windows 10 desktop search box and select the appropriate.
This does not work(no error message - %foo%
is just empty afterwards):
This one took me some time to figure out. I’m used to Visual Studio and the Access VBA editor, which both automatically insert these blanks into my code if I don’t do it myself. So when I wrote batch files with a simple text editor, I inserted these blanks too, without thinking.
Execute .exe and save the output to a variable
This line saves the output of foo.exe
to a variable named %bar%
:
(Credits for this go to user “lesmana” at Stack Overflow)
Disclaimer: I don’t try to understand it, I just copy/paste it every time I need it.
(The whole usage of the for
command looks equally complicated - to see it in all its beauty, type for /?
and read the help.)
Get the path and file name of the currently running batch file
There are other commands to get more file information, but to me the most important ones are these:
%~dp0
outputs the path of the current batch file%~nx0
outputs the name of the current batch file
To see it in action, put this into a batch file:
When the batch file is c:test.bat
, it will output this:
The number zero at the end of %~dp0
and %~nx0
refers to %0
, which is the currently executing batch file.
Likewise, if you pass a file as parameter %1
, you can get the name of that file by using %~nx1
instead of %~nx0
.
%~dp0
and %~nx0
are actually combined commands (you can also use %~n0
to get just the file name without extension, and %~x0
to get just the extension)
To see the complete list of commands, open the command line and type in call /?
.
Temporarily add a folder to the %PATH%
variable
When you need to refer files from a certain folder in a batch file several times and you don’t want to copy/paste the complete path every time, you can just add the folder to the %PATH%
variable.
When you don’t want to (or aren’t allowed to) do this permanently on the machine, you can set the %PATH%
variable in the batch file, which lasts only for the execution time of the batch file.
The following line appendsc:foo
to the existing content of the %PATH%
variable:
Afterwards, the %PATH%
variable contains everything it contained before plusc:foo
, which is probably what you want.
A second (but inferior) way would be:
This is probably not what you want, because it replaces the whole content of the %PATH%
variable by c:foo
!
In other words, %PATH%
will only contain c:foo
afterwards.
Beware: you won’t notice the difference as long as you only need files from c:foo
.
But as soon as you need some other command-line tool like git
or hg
(or some Windows helper like regsvr32.exe
), your batch file won’t find them anymore because you just deleted their locations from the %PATH%
.
Variables are global in nested batch file calls
Take a look at these two batch files:
batch1.bat:
batch2.bat:
The first batch file calls the second one, so variables with the same name are shared between the two.
This means that the last line in the first batch file (echo %var%
) will output bar
and not foo
!
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.
ASSOC | ATTRIB | CD | CHKDSK | CHOICE |
CLS | CMD | COMP | CONVERT | COPY |
DATE | DEL | DIR | DISKPART | DRIVERQUERY |
ECHO | EXIT | EXPAND | FC | FIND |

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

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.
Output
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
Output

command shows all the drivers list, which is huge.
ECHO
The batch command ECHO
is used for echoing commands on/off and printing message to the console.
Example
Output
This command ECHO displays Hello in the console as shown above.
Besides printing message, echo
is also used for deciding whether or not to display the command itself. Like in this example as well, in the first line we have turned OFF echo, which makes sure that commands themselves are not printed.
If that echo wasn’t turned off, then the output would have been like:
EXIT
The batch command EXIT
terminates and exits the console.
Example
In this example, as soon as HI
is printed in the console, EXIT
command will terminate the program and close the output console.
EXPAND
The batch command EXPAND
extracts the contents of .cab
file.
Example
This script will extract all the contents of xyz.cab
file to the same location where xyz.cab
is located.

finds the difference between the two files and displays them to console.
Example
This script will find the difference in the content of both files and list out all of them.
FIND
The batch command FIND
search the given file to find the desired string and if located, it displays the corresponding line in which the string exists.
Example
This script will search for the string “find me” in example.txt file and if it exists in example.txt, it will display the corresponding line on the console.
FORMAT
The batch command FORMAT
is used for formatting a drive of format FAT 16/32 or NTFS in Windows.
Example
This script will format E drive and overwrite previous contents.
HELP
This might be the one of the most important batch file commands because with this HELP
command we can know about all the other commands used in batch file or command prompt.
Example
Now this will display all the available commands with their functionalities in the console.
Since the list of commands is so much more, we have sliced the list and shown few here.
