Yes your assumption is correct and this is a real world problem
What iam trying to do is commenting the duplicate Ip's found in the text file ignoring the first occurance as to be valid IP for a valid mac and from the second occurance onwards commenting the duplicate IPs at the starting of the line.
file 1.txt with following entries as shown:
0152364|134444|10.20.30.40|015236433
0233654|122555|10.20.30.50|023365433

file 2.txt with following entries as shown:
0152364|134444|10.20.30.40|015236433
0233654|122555|10.20.30.50|023365433

i need to have the following output in 2.txt as shown:
0152364|134444|10.20.30.40|015236433
0233654|122555|10.20.30.50|023365433
#0789456|332211|10.20.30.40|078945633
#1234567|225522|10.20.30.50|123456733
#0321654|999999|10.20.30.40|032165433
#0456123|777899|10.20.30.40|045612333
***

The correct script i wrote is
for i in `cat 1.txt |cut -d"|" -f3`
do
cat 2.txt |sed "s/^\(.*\|$i\|.*)/#\1/g" > tmp.txt
mv tmp.txt 2.txt
done
But the above script will comment all the occurance.
Your help is appreciated.
Thanks
