PS3 select when wrong input given
Hi All

I am using the below code to chose a file to view :

Code:
PS3="Select file to view : "
select FILE in `ls`  QUIT
do
   if [ -e $FILE ] ; then
     clear
     cat  $FILE
  else
  break
  fi
  REPLY=''
done

Everything works fine as long as I am giving the correct choice .

But when i give a wrong option it hangs .
How to include a check so that if a wrong option is entered , throw a message saying to enter a valid choice.

NAME

       tv_grab_no_gfeed - Grab TV listings for Norway.

SYNOPSIS

       tv_grab_no_gfeed --help

       tv_grab_no_gfeed --configure [--config-file FILE] [--gui OPTION]

       tv_grab_no_gfeed [--config-file FILE]

			[--output FILE] [--quiet] [--debug]

       tv_grab_no_gfeed --list-channels [--config-file FILE]
			[--output FILE] [--quiet] [--debug]

DESCRIPTION

       Output TV and listings in XMLTV format for many stations available in Norway.

       First you must run tv_grab_no_gfeed --configure to choose which stations you want to receive.

       Then running tv_grab_no_gfeed with no arguments will get a listings for the stations you chose for five days including today.

OPTIONS

       --configure Prompt for which stations to download and write the configuration file.

       --config-file FILE Set the name of the configuration file, the default is ~/.xmltv/tv_grab_no_gfeed.conf.  This is the file written by
       --configure and read when grabbing.

       --gui OPTION Use this option to enable a graphical interface to be used.  OPTION may be 'Tk', or left blank for the best available choice.
       Additional allowed values of OPTION are 'Term' for normal terminal output (default) and 'TermNoProgressBar' to disable the use of
       Term::ProgressBar.

       --output FILE When grabbing, write output to FILE rather than standard output.

       --days N When grabbing, grab N days rather than 5.

       --offset N Start grabbing at today + N days.  N may be negative.

       --quiet Suppress the progress-bar normally shown on standard error.

       --debug Provide more information on progress to stderr to help in debugging.

       --list-channels	  Output a list of all channels that data is available
			     for. The list is in xmltv-format.

       --version Show the version of the grabber.

       --help Print a help message and exit.

ERROR HANDLING

       If the grabber fails to download data for some channel on a specific day, it will print an errormessage to STDERR and then continue with
       the other channels and days. The grabber will exit with a status code of 1 to indicate that the data is incomplete.

ENVIRONMENT VARIABLES

       The environment variable HOME can be set to change where configuration files are stored. All configuration is stored in $HOME/.xmltv/. On
       Windows, it might be necessary to set HOME to a path without spaces in it.

SUPPORTED CHANNELS

       For information on supported channels, see http://data.epg.no/
