I need to call a program in command line that will be executed in batch mode. This program receives a file with extension .jlink that contains a series of commands that the program JLink.exe will execute and then close.

I tried to execute in the following way:

os.system('C:/SEGGER/JLink_V490d/JLink.exe -CommanderScript D:\Files\CommandFile.jlink')

But this command executes the program in normal mode, not accepting the arguments.

How can I call as execution of command line and then send that command so the program executes in batch mode with those arguments?

Use subprocess:

subprocess.call(["C:\SEGGER\JLink_V490d\JLink.exe", 
                 "-CommanderScript", "D:\Files\CommandFile.jlink"])

You can also use shell=True to just execute a command directly in a shell (what you were trying to do with os.system), but this is not recommended because it's a security hazard.
