Using File Descriptors, traverse a list
I have written this code, and according to my research it SHOULD be going down the list until it is finished, but I am getting blank feedback. Nothing is being output as far as I can tell.

#!/bin/sh
while echo Enter to start traversing
read enter
do
read list <&3
echo $list
done

any ideas on whats going on? it's a rather straight forward experiment.

gst-feedback

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

NAME

       gst-feedback-0.8, gst-feedback - generate debug information for GStreamer bug reports

SYNOPSIS

       gst-feedback-0.8

       gst-feedback [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-feedback-0.8  scans	the system for various types of information that is useful to GStreamer developers to help diagnose user problems.
       Depending on the type of bug report, it might be useful to attach gst-feedback output when you contact the developers.

       Note: The current version of this script scans many directories: /usr/lib, /usr/local/lib,  /home,  /usr/include,  /usr/local/include,  and
       /home (again) for various GStreamer installations. Depending on your system, you might not want to do this.

       Note:  gst-feedback-0.8	dumps  a  lot of information about a system.  Some of this information might be considered sensitive. If this is a
       concern, review the information before posting to a public forum such as the GStreamer bug tracking system.

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

OPTIONS

       The following options are supported by gst-feedback 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: Generating Feedback Information

       example% gst-feedback-0.8

       Example 2: Generating Feedback Information and Redirecting Output and Errors to a File

       example% gst-feedback-0.8 &> myfeedback

       Example 3: Running the Wrapper Script and Displaying the Command Name

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

FILES

       The following files are used by this application:

       /usr/bin/gst-feedback-0.Executable to generate debug info for GStreamer bug reports

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