    WshShell.Run by default does not wait for the command to complete, so Log.Warning(Sys.Clipboard) happens before diff completes. To make it wait you need to specify True as the third parameter of the Run method.

    WshShell.Run(diffCmd, 0, True)

     

    Alternatively, you can use Python's built-in subprocess.check_output so you won't have to deal with the clipboard:

    import subprocess

    def diffTwoFilesToLog(file1, file2):
      output = subprocess.check_output(["C:\\Program Files (x86)\\GnuWin32\\bin\\diff.exe", file1, file2])
      output = output.decode()  # convert byte-string to string
      Log.Warning(output)
