Full Discussion: Problem in extraction when space is a field delimiter

This script handles one of your files. You may change the rows to print out. (here: 2 and 5 -> RTP="2 5")
I assume that the number of rows is usually six and only row 5 can be empty. If not we need to enhance the case-structure.

You need to run the script with the filename as first parameter:

Code:
    ./script.sh file.txt

Code:
#! /bin/bash

RTP="2 5"

while read -a A ; do
    case ${#A[@]} in
        5) A[5]=${A[4]} ; A[4]="" ;;
        *) : ;;
    esac
    L=""
    for n in ${RTP} ; do
        L="${L} ${A[$((N=n-1))]}"
    done
    echo "${L}"
done < <(awk '/SPOT/,/EOF/ {print}' ${1})
