I sometimes reach the limit of the batch language's capabilities.
I know, it is possible to calculate a cosine with SET /A
, but practical...?
Or how about an MD5 checksum of a string?
PHP, on the other hand, does have these functions available.
So why not use PHP in batch files?
Start by downloading and installing PHP.
Next copy the following code and save it as MD5.BAT:
Or if you did not add your PHP directory to the PATH:
I love these one-liners! 😉
A good reason to try and place the code in a single line is that it can be placed inside another FOR /F loop.
The MD5 example could be used in a FOR /F
loop to get the result in an environment variable:
Note that I left the IF
statement outside the FOR /F
loop.
There is no law against inclusion in the loop, but consider it best practice to keep the part between parentheses as "clean" as possible.
Likewise you would want to try and avoid nesting FOR /F
loops.
Even though
may work, a "cleaner" method, if you insist on a one-liner, would be:
Why I prefer the latter?
Try nesting each version in a third FOR /F
loop and you'll understand: each level of nesting would require an extra "level" of escaping escape characters!
If you reach this level of complexity, consider making your code more readable by using subroutines.
They may slow down execution of the batch file, but they may save you lots of time if you need to do some maintenance on the code in, say, a year or so.
Now test it, run:
MD5.BAT password
If all went well, the batch file should return 5f4dcc3b5aa765d61d8327deb882cf99
, the MD5 checksum value for the string password
.
Running:
MD5.BAT PASSWORD
should return 319f4d26e3c536b5dd871bb2c52e3178
.
Likewise we can write a batch file to calculate the SHA1 checksum of a string:
Note that I avoid spaces in the actual PHP command following the -r
switch.
I found out the hard way that with spaces the batch file becomes very unreliable.
Enclosing the PHP command in doublequotes is supposed to fix that, but I did not get reliable results.
The options for "new technology" batch files are unlimited!
Binary to decimal conversion:
:: https://www.robvanderwoude.com/batchphp.php :: Usage: "bin2dec 1101" returns "13" @PHP -r print(bindec(%~1));
OK, bad example, this can also be done using SET /A for numbers below 32768.
But how about binary to hexadecimal conversion?
:: https://www.robvanderwoude.com/batchphp.php :: Usage: "bin2hex 11001101" returns "0xCD" @PHP -r print('0x'.strtoupper(dechex(bindec(%~1))));
Or decimal to binary?
:: https://www.robvanderwoude.com/batchphp.php :: Usage: "dec2bin 13" returns "1101" @PHP -r print(decbin(%~1));

You don't really need to embed PHP code in batch files, PHP can handle command lines quite well.
Let's take the MD5 function. An MD5.PHP for command line use would look like this:
#! php.exe -q <?php if ( $argv[1] ) { print( md5( $argv[1] ) ); } ?>
You can run it using the command PHP MD5.PHP "string"
to get the MD5 checksum for "string".
Or you can define a file type association for PHP and just run the command MD5.PHP "string"
to get the checksum.
Even the definition of the file type association can be automated. Just run the following batch code once:
Definitely unsuited for one-liners, but you can use PHP based WMI scripts.
Create the following script to list some monitor properties:
<?php
$wmi_object = new COM( "winmgmts://./root/WMI" );
$wmi_instances = $wmi_object-<ExecQuery( "SELECT * FROM WmiMonitorID" );
foreach ( $wmi_instances as $instance ) {
print( "Active : {$instance->Active}\n" );
print( "InstanceName : {$instance->InstanceName}\n" );
print( "ManufacturerName : " );
if ( $instance->ManufacturerName ) {
foreach ( $instance->ManufacturerName as $value ) {
print( "{$value};" );
}
}
print( "\n" );
print( "ProductCodeID : " );
if ( $instance->ProductCodeID ) {
foreach ( $instance->ProductCodeID as $value ) {
print( "{$value};" );
}
}
print( "\n" );
print( "SerialNumberID : " );
if ( $instance->SerialNumberID ) {
foreach ( $instance->SerialNumberID as $value ) {
print( "{$value};" );
}
}
print( "\n" );
print( "UserFriendlyName : " );
if ( $instance->UserFriendlyName ) {
foreach ( $instance->UserFriendlyName as $value ) {
print( "{$value};" );
}
}
print( "\n" );
print( "UserFriendlyNameLength : {$instance->UserFriendlyNameLength}\n" );
print( "WeekOfManufacture : {$instance->WeekOfManufacture}\n" );
print( "YearOfManufacture : {$instance->YearOfManufacture}\n" );
print( "\n" );
}
?>
Save the file as wmimonitorid.php
.
For PHP version 5.4.5 or later, the following modification in php.ini
is required:
[COM_DOT_NET] extension=php_com_dotnet.dll
Now run the following command:
php.exe -f wmimonitorid.php
(assuming php.exe is in the PATH)
The command's output may look like this:
Active : 1 InstanceName : DISPLAY\SAM083A\7&cf6ea47&1&UID4194576_0 ManufacturerName : 83;65;77;0;0;0;0;0;0;0;0;0;0;0;0;0; ProductCodeID : 48;56;51;65;0;0;0;0;0;0;0;0;0;0;0;0; SerialNumberID : 88;88;88;48;48;48;48;48;48;48;0;0;0;0;0;0; UserFriendlyName : 83;77;83;50;52;65;52;53;48;0;0;0;0; UserFriendlyNameLength : 13 WeekOfManufacture : 41 YearOfManufacture : 2011 Active : 1 InstanceName : DISPLAY\SAM0467\7&cf6ea47&1&UID4194578_0 ManufacturerName : 83;65;77;0;0;0;0;0;0;0;0;0;0;0;0;0; ProductCodeID : 48;52;54;55;0;0;0;0;0;0;0;0;0;0;0;0; SerialNumberID : 88;89;90;48;48;48;48;48;48;49;0;0;0;0;0;0; UserFriendlyName : 83;121;110;99;77;97;115;116;101;114;0;0;0; UserFriendlyNameLength : 13 WeekOfManufacture : 12 YearOfManufacture : 2009
Instead of PHP code embedded in batch files, you can also use Perl.
Let's take the MD5 function. A Perl based MD5Perl.bat would look like this:
Or for SHA-1:
Dealing with command lines means not all characters are allowed.
Ampersands, single and double quotes, even spaces in arguments can break scripts.
Make sure to thoroughly test the scripts presented here, and your own, or in fact any script, before using them for "production".
