Hi,
I would like to modify the script [1].
Change data*.list to data1.list in the line below, it did not work.
Actually, to begin the script should read data1.list.

Code:
     { rm $CARD; sed -e "s/data*/data1/g" > $CARD; } < $CARD

thanks

 #For Submiting the batchjobs                                                                                                                                           
SubmitBatchJob () {
    max=$FileId
    for (( k=0; k < $max ; ++k )) ;
      do
      echo "SHELL JOB ================ $k =============="
      if [ $k == 0 ]; then
          source $SCRIPT
      else
          if [ $k > 0 ]; then
              { rm $CARD; sed -e "s/data$k/data$((k+1))/g" > $CARD; } < $CARD
              source $SCRIPT
              echo "SUCCESFULLY DONE.."
          else
              if [ $k = $max ]; then
                  echo "TERMINATES.."
              fi

    done

speaker-test

SPEAKER-TEST(1) 					      General Commands Manual						   SPEAKER-TEST(1)

NAME

       speaker-test - command-line speaker test tone generator for ALSA

SYNOPSIS

       speaker-test [-options]

DESCRIPTION

       speaker-test generates a tone that can be used to test the speakers of a computer.

       speaker-test  by default will test the default device. If you want to test another sound device you will have first to get a list of all of
       the sound cards in your system and the devices associated with those cards. Notice that there might be for example, one device  for  analog
       sound, one for digital sound and one for HDMI sound.  To get the list of available cards and devices you can run aplay -L.

       $ aplay -L
       null
	   Discard all samples (playback) or generate zero samples (capture)
       default:CARD=ICH5
	   Intel ICH5, Intel ICH5
	   Default Audio Device
       front:CARD=ICH5,DEV=0
	   Intel ICH5, Intel ICH5
	   Front speakers
       surround40:CARD=ICH5,DEV=0
	   Intel ICH5, Intel ICH5
	   4.0 Surround output to Front and Rear speakers
       (...)

       in  the	above example, there are four devices listed: null, default, front and surround40. So, if you want to test the last device you can
       run speaker-test -Dsurround40:ICH5 -c 6. The -c option will indicate that the six audio channels in the device have to be tested.

OPTIONS

       -c | --channels NUM
	      NUM channels in stream

       -D | --device NAME
	      PCM device name NAME

       -f | --frequency FREQ
	      sine wave of FREQ Hz

       --help Print usage help

       -b | --buffer TIME
	      Use buffer size of TIME microseconds.  When 0 is given, use the maximal buffer size.  The default value is 0.

       -p | --period TIME
	      Use period size of TIME microseconds.  When 0 is given, the periods given by -P option is used.  The default value is 0.

       -P | --nperiods PERIODS
	      Use number of periods.  The default value is 4.

       -r | --rate RATE
	      stream of RATE Hz

       -t | --test pink|sine|wav
	      -t pink means use pink noise (default).

	      Pink noise is perceptually uniform noise -- that is, it sounds like every frequency at once.  If you can hear any tone it may  indi-
	      cate resonances in your speaker system or room.

	      -t sine means to use sine wave.

	      -t wav means to play WAV files, either pre-defined files or given via -w option.

	      You can pass the number from 1 to 3 as a backward compatibility.

       -l | --nloops COUNT

	      Specifies the number of loops.  Zero means to run infinitely.

	      When -s option below with a valid channel is given, speaker-test will perform always a single-shot without looping.

       -s | --speaker CHANNEL
	      Do  a  single-shot  speaker  test for the given channel.	The channel number starts from 1.  The channel number corresponds to left,
	      right, rear-left, rear-right, center, LFE, side-left, side-right, and so on.

	      For example, when 1 is passed, it tests the left channel only once rather than both channels with looping.

       -w | --wavfile
	      Use the given WAV file for the playback instead of pre-defined WAV files.

       -W | --wavdir
	      Specify the directory containing WAV files for playback.	The default path is /usr/share/sounds/alsa.

USAGE EXAMPLES

       Produce stereo sound from one stereo jack:
	 speaker-test -Dplug:front -c2

       Produce 4 speaker sound from two stereo jacks:
	 speaker-test -Dplug:surround40 -c4

       Produce 5.1 speaker sound from three stereo jacks:
	 speaker-test -Dplug:surround51 -c6

       To send a nice low 75Hz tone to the Woofer and then exit without touching any other speakers:
	 speaker-test -Dplug:surround51 -c6 -s1 -f75

       To do a 2-speaker test using the spdif (coax or optical) output:
	 speaker-test -Dplug:spdif -c2
