why do you want to use "echo" ? try remove this and try again

#!/bin/ksh
read IP_ADD
echo nslookup $IP_ADD  2>&1| tee log1.txt
cat  /amex/gcst/siva/Testr/log1.txt
awk '/^Name:/{print $2} ' log1.txt

Just include -F: in the awk statement..

awk -F: '/^Name:/{print $2} ' log1.txt
#Output
            spdma505.gcg.ikl.us.ecil.com

To remove those leading spaces..try..

awk -F: '/^Name:/ {print $2}'| tr -d " " < log1.txt
#Output:
spdma505.gcg.ikl.us.ecil.com

If all that you want to do is extract the "Name" field, we don't need workfiles.

#!/bin/ksh
read IP_ADD
nslookup "${IP_ADD}"  2>&1 | awk '/^Name:/{print $2} '
