Parse file and save in etc/hosts

Comment:

Hello: I am very new to shell programming and in need of some help. I have a file sc.cfg that contains some ip addresses as ASCIP. sc.cfg -------------- ASCIP=3.87.87.3/255.255.252.0 ASCIP=3.87.86.41/255.255.252.0 ASCIP=3.87.87.45/255.255.252.0 -------------- All I need is a shell script that opens this file (sc.cfg) takes out the 3 ip addresses and stores it in etc/hosts... Please help. Thank You & Best Regards

The IP number without the hostname won't do you a lot of good. #!/bin/sh cat sc.cfg | while read line ; do IP=`echo $line | cut -f 2 -d "=" | cut -f 1 -d "/"` if [ `grep -c $IP /etc/hosts` -eq 0 ] ; then echo $IP >> /etc/hosts fi done
