Shell Programming and Scripting

Hi folks,

I have the following select function:
select_vs_plugin()
{
export VS_LIST=`cat VsList.lst`
while [[ "1" = "1" ]]
do
echo
echo
echo ===================================================================
============
echo Please select Video Server Plugin
echo ===================================================================
============
echo
select selectedVsPlugin in $VS_LIST Quit
do
if [[ -z "${selectedVsPlugin}" ]] ; then
echo "\n**** !! Invalid Option !! ****\n"
else
break
fi
done
if [[ ${selectedVsPlugin} = "Quit" ]] ; then
echo "\n**** End of video servers selection ****\n"
break
else
export SELECTED_VS=${selectedVsPlugin}
echo The select video server plugin is : ${SELECTED_VS}
fi
done
}

The configuration file VsList.lst contains the following video servers names:
MediaBase XMP 7.2
Maestro 4
SeaChange iTV 2.5

The function suppose to display those names in selection menu.
Now,the selection diplaying looks as the following:
===============================================================================
Please select Video Server Plugin
===============================================================================

1) MediaBase
2) XMP
3) 7.2
4) Maestro
5) 4
6) SeaChange
7) iTV
8) 2.5
9) Quit
#?


The wrapped displaying occured due to the space in the names in tthe lst file.

How can i overcome on this space problem?

Thanks in advance.

Change the IFS variable setting as,

export IFS='
'

It will work.

Hi muthukumar,

Thanks for your reply!
I didn't understand the meaning of "IFS parameter".
To which parameter did you mean?

Thanks in advance,

IFS is default shell parameter to give strings patterns based on the field separator. You are doing operation as, export VS_LIST=`cat VsList.lst` so that it will take ' ' <space> as FS so try to change newline to do your work.

Thanks again muthukumar!

Frankly,i'm looking for a solution that not require a shell parameters changing,because it might harm other functions in the program.

Any other solutions will be greatefully accepted.
