Wow. Thanks so much bakunin. You are certainly right that it is better to "teach a man to fish". I struggled with this for hours before i posted as it was hard finding something on google that was relevant enough to my problem to learn from. So now not only am i one step closer to resolving my problem i have learned a lot more.

I'll have a play and let you know how i get on.

------ Post updated at 05:24 PM ------

Having much more fun now i know how the array works, but I'm struggling to get the row to display as a whole selection. The array is splitting all the individual items into options.

I want to display like:

1. apples : 1111 : aaaa
2. pears : 2222 : bbbb
3. peaches : 3333 : cccc

but its displaying

1. apples
2. 1111
3. aaaa
4. pears
5. 2222

etc

Here is my new code:

Code:
options=( $(awless -l list routetables --columns ID,NAME,VPC --filter VPC=vpc-0025xxxxxxxe52 | grep rtb | sed 's/|//g') )
selection=""
options[((${#options[@]}+1))]="EXIT"

selection=""

PS3="Enter 1-$((${#options[@]}-1)) to select an item or ${#options[@]} to exit => "

#PS3="Select an item or 5 to exit => "
select selection in ${options[@]} ; do
     case "$selection" in
          "")
               echo "You selected a non-existing item"
               ;;

          "EXIT")
               echo "You are leaving the loop."
               break
               ;;

          *)
               echo "You selected $selection"
               ;;

     esac
done

echo "here is the end of the program"
exit 0

wxpaste

wxpaste(1x)															       wxpaste(1x)

NAME

       wxpaste - output a cutbuffer to stdout

SYNOPSIS

       wxpaste [options]

DESCRIPTION

       wxpaste outputs the contents of the specified cutbuffer to stdout. If no cutbuffer is specified, the cutbuffer 0 will be used as default.

OPTIONS

       -cutbuffer number
	      The data will be pasted from the specified cutbuffer, instead of the default 0.

       -display display-name
	      Specifies the display where wxpaste should look for the data to be pasted.

       -selection [selection-name]
	      The data will be copied from the named selection. If cutting from the selection fails, the cutbuffer will be used. The default value
	      for the selection name is PRIMARY.

BUGS

       The -selection option must be the last one. The syntax could be
	      cleaned, but backwards compatibility prevents that...

	      INCR and MULTIPLE selection types are not handled. Actually, only simple text selections are handled, wich should be enough for most
	      uses of a utility such as this.
