        """
        Get the latest captured .cap file from ReST API server to local Linux drive.

        Parameters
            port: Format:[IxiaIpAddress, slotNumber, cardNumber]
                  Example: [ixChassisIp, '2', '1']

            typeOfCapture: data|control

            saveToTempLocation: For Windows:
                                    Where to temporary save the .cap file on the ReST API server: 
                                    Provide any path with double backslashes: C:\\Temp.
                                    The folder will be created if it doesn't exists.

                                For Linux, value= 'linux'.
 
            localLinuxLocation: Where to save the .cap file on the local Linux machine.

            appendToSavedCapturedFile: Add a text string to the captured file.

        Example:
            captureObj.getCapFile([ixChassisIp, '2', '1'], 'control', 'c:\\Temp', '/home/hgee/test')
