Hi2all,

I have file 1 which contents are:

#PTEDFLE 10.228.101.180
#PTEDFL8 10.228.101.180
#PTEDFLB 10.228.101.180
#PTEDFLF 10.228.101.176
#PTEDFLP 10.228.101.154
#PTEDFLN 10.228.101.154
#PTEDFLM 10.228.101.154

and other file 2 which holds data from first column of file 1.

I want to append with ip address (2nd column of file 1) every line in file 2 which contain column 1 in file 1.

This doesn't work:

while read term ip
do sed '/$term/ a\ $ip' 2 > test
done < 1

But if I try with appending only one value like this, it works:

sed '/#PTEDFLE/ a\ 10.228.101.180 2 >test

What am I missing??

the problem may be in this line

show your file2, and show how your output will be like

Ok, I figured it out, this is the solution:

cp 2 test
while read term ip;
do sed "/$term/ a\ $ip" test > test.$$ && mv test.$$ test;
done < 1
