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
PING www.amazon.com (176.32.98.166) 56(84) bytes of data.

--- www.amazon.com ping statistics ---

Pinging www.google.com

64 bytes from mil01s16-in-f19.1e100.net (173.194.35.19): icmp_seq=1 ttl=56 time=26.8 ms

rtt min/avg/max/mdev = 26.844/26.844/26.844/0.000 ms
+ ~ $

That is on and with:
Code:
uname -a

Hope this helps

You guys are quick and very helpful! Thank you very much.
My original question was answered and I'll use something like below to start with. I'll incorporate the other suggestions to make my script better.

Code:
$ cat ping_names.txt 

LIST1="www.fsf.org www.google.com"
LIST2="www.redhat.com www.apple.com"
LIST3="www.fsf www.apple.com"

Code:
#!/bin/bash

source ./ping_names.txt

ref=$1

for H in ${!ref};  
   do ping -c 1 $H;     
done;

Code:
$ ./check.sh LIST1
PING www.fsf.org (208.118.235.131) 56(84) bytes of data.
64 bytes from www.fsf.org (208.118.235.131): icmp_req=1 ttl=52 time=84.8 ms

--- www.fsf.org ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 84.859/84.859/84.859/0.000 ms
PING www.google.com (74.125.25.147) 56(84) bytes of data.
64 bytes from pa-in-f147.1e100.net (74.125.25.147): icmp_req=1 ttl=47 time=19.6 ms

--- www.google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 19.685/19.685/19.685/0.000 ms

You don't need the ref=$1. Try for H in ${!1};
