And is it possible to do the same thing without using a label and jump?
1-) actually i think all the same things..because $! --> means dont process for last line and go for others..already there is not a newline after the last line..
2-) without using a label and jump --> is not successfull if you use without label then result is process just every two lines.

gst-register

gst-register-0.8(1)						   User Commands					       gst-register-0.8(1)

NAME

       gst-register-0.8, gst-register - register GStreamer plugins

SYNOPSIS

       gst-register-0.8 [gst-std-options]

       gst-register [gst-std-options] [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-register-0.8  registers  all of the GStreamer plugins on your system. gst-register-0.8 creates a listing of their properties so that on
       startup of GStreamer-based applications, you do not need to load plugins until you need them.

       When run as the root user, gst-register-0.8 creates the Global GStreamer plugin registry which is stored  in  /var/cache/gstreamer-X.X/reg-
       istry.xml, where X.X is the GStreamer major and minor version number.

       When  run  as  a  user  other  than the root user, gst-register-0.8 creates a user registry ~/.gstreamer-X.X/registry.xml, where X.X is the
       GStreamer major and minor version number.

       Programs that uses GStreamer use the user plugin registry if it exists, and use the Global plugin registry if not.

       gst-register is a wrapper script that runs the latest installed version of gst-register-X.X. For example, if both gst-register-0.7 and gst-
       register-0.8 are installed on your system, gst-register runs gst-register-0.8.

OPTIONS

       The following options are supported by gst-register-0.8 and gst-register:

       gst-std-options Standard options available for use with most GStreamer applications.  See gst-std-options(5) for more information.

       The following options are supported by gst-register only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Running the Wrapper Script and Displaying the Command Name

       example% gst-register --print
       /usr/bin/gst-register-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-register-0.Executable to register GStreamer plugins

       /usr/bin/gst-register   Wrapper script that runs the latest installed version of gst-register-X.X

       /var/cache/gstreamer-X.XGStreamer.global plugin registry, where X.X is the GStreamer major and minor version number.

       ~/.gstreamer-X.X/registrGStreamer user plugin registry, where X.X is the GStreamer major and minor version number.
