sed or awk

Hello All, I am trying to program a script to change the ip.

I would like that the user enters
and since we use /24 masks I can just "calculate" from sed or awk

the gateway the network and the broadcast

Any help would be appreciated.

You can do this quite easily with a shell script and internal string manipulation - no need to invoke other processes:

read -p "enter the IP> " ip

printf "%-20s = %s\n" "ip" "$ip"
printf "%-20s = %s\n" "gateway" "$gateway"
printf "%-20s = %s\n" "network" "$network"
printf "%-20s = %s\n" "broadcast" "$broadcast"
