Shell Programming and Scripting

Hi, i am new in shell script. i have given a task to make a C-shell script. I have list of ip address and device name respectively. For example;

cal 1 : 100.21.25.10
cal 2 : 100.21.25.11
cal 3 : 100.21.25.12
cal 4 : 100.21.25.14
and so on...

Right now, i have this.

Code:

#! /bin/csh -f

set device = (cal1 cal2 cal3)
set ipaddress = (100.21.25.10 100.21.25.11 100.21.25.12)
set highspace=90

foreach data($ipaddress)

set rspace = `rsh $data df -k | grep /dev/dsk/c0t0d0s0 | awk '{print $5}' |cut -c1-2`

if (${rspace} >= ${highspace}) then
    echo "Please Housekeep $device "
endif

end

Output:

100.21.25.10
61
Please Housekeep cal1 cal2 cal3

why its only iterate one time? And how to have ip address will link to device name?

thanks
