Creating menu list from configuration file
Hi folks,

I have the following function ,which generates menu for installation type:
Code:
select_install_type()
{

        echo
        echo ========================================
        echo Please select the type of installation:
        echo ========================================
        echo

        pass=fail
        until [[ ${pass} = pass ]] ; do

        select installType in `cat /tmp/layers.conf`
                do
if [[  ${installType} = "Quit" ]] ; then

                        echo "\n**** !! Exiting by user's request !! ****\n"
                        exit 2

                elif  [[ -z "${installType}" ]] ; then

                        echo "\n**** !! Invalid Option !! ****\n"
                        continue
               elif [[  ${installType} = "Database_Layer"  ]] ; then
                        export installType=DatabaseLayer
                        pass=pass
                        break
elif [[  ${installType} = "RiGHTv_Admin_Layer"  ]] ; then
                        export installType=RTEAdminLayer
                        pass=pass
                        break

                elif [[  ${installType} = "RTEsub_Layer"  ]] ; then
                        export installType=RTESubLayer
                        pass=pass
                        break

                else

                        echo "Invalid Install Type"
                        exit
                fi

        done
      done
}

The content of conf file layers.conf is:
Code:
root# cat layers.conf
Database Layer
RiGHTv Adminstration Layer
RTE Subscribers Layer
Quit

If I run it:
Code:
root# ./get_layer.ksh

========================================
Please select the type of installation:
========================================

1) Database
2) Layer
3) RiGHTv
4) Adminstration
5) Layer
6) RTE
7) Subscribers
8) Layer
9) Quit
#?

As you can see ,The problem is the spaces between the words which cause the menu to display each word in different line.
How can I overcome it?
The expected result is:
Code:
========================================
Please select the type of installation:
========================================

1) Database Layer
2) RiGHTv Adminstration Layer
3) RTE Subscribers Layer
4) Quit
#?

Thanks in advance,
Nir
