I aim to use a Python script that calls a batch script, which in turn calls a cmd file to load environment variables and run commands with them.

In my batch script, the first line loads environment variables by calling a cmd file, and the second line executes a command with the loaded environment and its arguments.

However, my problem is that the first line opens a new shell instance, and the second line is executed in the original shell instance before the environment is loaded.

I need to figure out how to run the commands in the new shell instance with the loaded environment.

cmd /k "C:\Program Files (x86)\Microsoft GSDK\Command Prompts\GamingDesktopVars.cmd" GamingDesktopVS2017
wdapp unregister myAppName

Executing Commands in a New Shell Instance with Loaded Environment

When running a batch script, sometimes it is necessary to load environment variables before executing commands. However, when the script calls a cmd file to load the environment, it opens a new shell instance, and the subsequent commands are executed in the original shell instance before the environment is loaded. This problem can be solved by executing the commands in the new shell instance with the loaded environment. In this post, we will discuss how to achieve this using a Python script that calls a batch script, which in turn calls a cmd file to load environment variables and run commands with them.

Python Script

Let’s start by creating a Python script that calls the batch script. The Python script will use the subprocess module to execute the batch script and capture its output. Here is an example Python script:

python
import subprocess

output = subprocess.check_output(['path/to/batch/script.bat'])
print(output.decode('utf-8'))

This script calls the batch script located at path/to/batch/script.bat and captures its output. The check_output function waits for the batch script to finish executing before returning its output. The decode function is used to convert the output from bytes to a string.

Batch Script

Next, let’s create the batch script that loads environment variables and runs commands with them. Here is an example batch script:

batch
@echo off

call "C:Program Files (x86)Microsoft GSDKCommand PromptsGamingDesktopVars.cmd" GamingDesktopVS2017

start "" cmd /c "wdapp unregister myAppName"

This script loads environment variables by calling the cmd file located at "C:Program Files (x86)Microsoft GSDKCommand PromptsGamingDesktopVars.cmd". The call command is used to execute the cmd file in the current shell instance, so the environment variables are loaded into the current environment.

The start command is used to open a new shell instance and execute the subsequent command in it. The /c option is used to execute the command and then exit the new shell instance. The "" argument is used to specify an empty window title.

Cmd File

Finally, let’s create the cmd file that sets path variables. Here is an example cmd file:

cmd
@echo off

set GRDKEDITION=

if /i "%1"=="GamingDesktopVS2017" (
  call :SetVS2017
) else (
  echo You must specify GamingDesktopVS2017 on the command line.
  exit /b 1
)

if "%GRDKEDITION%"=="" (
  if not "%2"=="" (
    set GRDKEDITION=%2
  ) else (
    call :GetLatestGRDK
  )
)

if %DTARGETVSVER% GEQ 15.0 (
  set GRDKVSPRERELEASE=-prerelease

  if "%GRDKVSPRODUCTS%"=="" (
    if not "%3"=="" (
      set GRDKVSPRODUCTS= -products %3
    )
  ) else (
    set GRDKVSPRODUCTS= -products %GRDKVSPRODUCTS%
  )

  if "%GRDKVSVERSION%"=="" (
    if not "%4"=="" (
      if not "%4"=="NOPRE" (
        set GRDKVSVERSION= -version %4
      )
    )
  ) else (
    set GRDKVSVERSION= -version %GRDKVSVERSION%
  )
)

:GetLatestGRDK
echo Getting the most recent GXDK edition installed...
for /f "tokens=2,3" %%a in ('reg query "HKLMSOFTWAREMicrosoftXboxLiveGdkVersions" /v "LatestGDKEdition" ^| findstr "REG_SZ"') do (
  set GRDKEDITION=%%b
)
if "%GRDKEDITION%"=="" (
  echo Failed to find the most recent GXDK edition installed.
  exit /b 1
)
exit /b 0

This cmd file sets path variables based on the specified edition of the Gaming Desktop Kit (GDK). The if statement checks if the first argument is "GamingDesktopVS2017", which is the name of the edition we want to use. If it is, the :SetVS2017 label is called to set the appropriate path variables. If it isn’t, an error message is displayed, and the script exits with an error code of 1.

The :SetVS2017 label sets the path variables for the specified edition of the GDK. The set command is used to set each variable. The exit /b 0 command is used to exit the script with a success code of 0.

The :GetLatestGRDK label is called if the GRDKEDITION variable is not set. This label gets the most recent edition of the GDK installed on the system by querying the registry. The for loop is used to parse the output of the reg query command and set the GRDKEDITION variable to the second token of the second line of output. If the variable is not set, an error message is displayed, and the script exits with an error code of 1.

Conclusion

In this post, we have discussed how to execute commands in a new shell instance with loaded environment variables. We achieved this using a Python script that calls a batch script, which in turn calls a cmd file to load environment variables and run commands with them. We hope this post has been informative and helpful.

To execute the second line of the batch script in the new shell instance that is opened by the first line, you can use the start command in the batch script.

Change the first line of the batch script to the following:

start cmd /k "C:\Program Files (x86)\Microsoft GSDK\Command Prompts\GamingDesktopVars.cmd" GamingDesktopVS2017

This will open a new instance of the command prompt, run the GamingDesktopVars.cmd file to set the environment variables, and then return control to the batch script.

Then, add the start command before the second line of the batch script to execute the wdapp unregister command in the new shell instance:

start wdapp unregister myAppName

This will execute the wdapp unregister command in the new shell instance where the environment variables have been set.

The updated batch script should look like this:

start cmd /k "C:\Program Files (x86)\Microsoft GSDK\Command Prompts\GamingDesktopVars.cmd" GamingDesktopVS2017
start wdapp unregister myAppName

Here are a few additional thoughts:

If you want the batch script to wait for the new shell instance to finish executing before continuing, you can use the start /wait command instead of just start.
You can also use the call command to execute the GamingDesktopVars.cmd file and return control to the batch script, rather than opening a new shell instance. However, this will not allow you to execute the wdapp unregister command in the new shell instance where the environment variables have been set.
If you want to pass arguments to the GamingDesktopVars.cmd file, you can do so by adding them after the file name in the start command, like this: start cmd /k "C:\Program Files (x86)\Microsoft GSDK\Command Prompts\GamingDesktopVars.cmd" GamingDesktopVS2017 argument1 argument2.
Make sure to use the full path to the GamingDesktopVars.cmd file in the start command.

I hope this helps! Let me know if you have any other questions.

If you edit your bat (GamingDesktopVS2017.cmd), and add:

@echo off && cd /d "c:\folder\to\where\the\bat\are\" 
SET "DPLATFORM=VS2017 
SET "DTARGETVS=Visual Studio 2017" 
SET "DTARGETVSVER=15.0"

And run/call this:

echo=exit|cmd /v /k GamingDesktopVS2017.cmd wdapp unregister myAppName

Why you are using cmd /k?

About “C:\Program Files (x86)\Microsoft GSDK\Command Prompts\GamingDesktopVars.cmd” does:

rem :: the bat only check if your are passing this argument :GamingDesktopVS2017 
rem :: if positive, then set same variable that you can add in your bat :

IF /I "%1"=="GamingDesktopVS2017" (

CALL :SetVS2017 => call label :SetVS2017

)ELSE (

ECHO You must specify GamingDesktopVS2017 on the command line.

EXIT /B 1

)

and the label do this:

:SetVS2017 SET DPLATFORM=VS2017 
SET DTARGETVS=Visual Studio 2017 
SET DTARGETVSVER=15.0 
GOTO :EOF

Just move this settings above to your bat!
