For Ongoto:
(I just inserted linebreaks for readability)
Code:
✔ ~ $ cat testscript.sh list.txt ; sh testscript.sh list1

#!/bin/bash
[[ -z "$1" ]] && echo "You passed no arguments!" && exit 1
SEARCH="$1"
oIFS="$IFS"
IFS="\"= "
FILE_LIST="$HOME/list.txt"

grep ^$SEARCH "$FILE_LIST"|while read var entries;do
	for entry in $entries;do
		echo "Pinging $entry"
		ping -c1 "$entry"
	done
done

list1="www.amazon.com www.google.com"
list2="www.redhat.com www.apple.com"
list3="www.amazon.com www.apple.com"

Pinging 
ping: unknown host 
Pinging www.amazon.com

That is on and with:
Code:

Hope this helps

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
