Hi
I want to do the following:
1. Create a number of Gloabla varibale "ROUTE_IP_xx" based on a counter. As xx sould be from 1-10.
ie ROUTE_IP_1
ROUTE_IP_2
.
.
ROUTE_IP_10
2. I want to initalize all of these variable to 0.0.0.0
ie ROUTE_IP_1='0.0.0.0'
3. I want to be able to access this global variable through out the code.
ie $ROUTE_IP_1
Following is waht I have got. I have generated the GLOBAL variable properly. But I could not figure out how to access them.
Please let me know if you have any suggestion?
Thanks,
Sabina
#!/bin/sh
ROUTE_MAX_NO_OF_ENTRY=10
count=1
while [ $count -le $ROUTE_MAX_NO_OF_ENTRY ]
do
ip_addr=ROUTE_IP_${count}
echo "ip_addr $ip_addr"
export $ip_addr='0.0.0.0'
tmp=`echo '$'$ip_addr`
echo $tmp
count=`expr $count + 1`
done

TPING(1) LAM COMMANDS TPING(1)
NAME
tping - Send echo messages to LAM nodes.
SYNOPSIS
tping [-hv] [-c count] [-d delay] [-l length] nodes
OPTIONS
-h Print the command help menu.
-v Turn OFF verbose mode.
-c count Send count messages.
-d delay Delay delay seconds between each message.
-l length Each message is length bytes long.
DESCRIPTION
The tping command sends messages to, and collects replies from, a list of nodes, via the LAM echo server. It is similar to the UNIX
ping(8) command, and is used as a quick diagnosis of the LAM network.
Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it
completes, with a delay of 1 second between roundtrips. After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis-
tics about all roundtrip messages.
EXAMPLES
tping h
Echo messages to the local node.
tping -v n7 -l 1000 -c 10
Echo 1000 byte messages to node 7. Stay silent while working. Stop after 10 roundtrips and report statistics.
BUGS
There is no built-in timeout and tping will wait forever to receive an echo. If no echo is received, due to a dead link or node, tping
hangs. Stop the process with a keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of
lamwipe(1) is deprecated).
