Use the following with the -e option, not the -n option:

sed -e 's/192.168.0.1/172.16.0.1/g' in-file > out-file

With in-file containing:
abc.com           192.168.0.1
localhost.abc.com 127.0.0.1

And resulting out-file containing:
abc.com           172.16.0.1
localhost.abc.com 127.0.0.1

Hi all

I have problem to replace words
from 192.168.0.1 to 172.16.0.1 in file abc.com

file content:
abc.com           192.168.0.1
localhost.abc.com 127.0.0.1

I tried:

sed -n 's/192.168.0.1/172.16.0.1/w abc.com.tmp'
abc.com

file abc.com.tmp
only shows l line
abc.com           172.16.0.1
and missing localhost.abc.com 127.0.0.1



I tried and it is same!
sed -n 's/192.168.0.1/172.16.0.1/gw abc.com.tmp'
abc.com

I can't use perl because the sed is within shell
script

TIA
