      public static List<String> runNative(String cmdToRun)
      Executes a command on the native command line and returns the result. This is a convenience method to call Runtime.exec(String) and capture the resulting output in a list of Strings. On Windows, built-in commands not associated with an executable program may require cmd.exe /c to be prepended to the command.
      Parameters:
      cmdToRun - Command to run
      Returns:
      A list of Strings representing the result of the command, or empty string if the command failed

    • runNative

      public static List<String> runNative(String[] cmdToRunWithArgs)
      Executes a command on the native command line and returns the result line by line. This is a convenience method to call Runtime.exec(String[]) and capture the resulting output in a list of Strings. On Windows, built-in commands not associated with an executable program may require the strings cmd.exe and /c to be prepended to the array.
      Parameters:
      cmdToRunWithArgs - Command to run and args, in an array
      Returns:
      A list of Strings representing the result of the command, or empty string if the command failed
