Bash script for ping in your own subnet
I have a question for one who wants to help me.
I want to create a bash script to ping IP-adresses. It must first ask me the beginnen IP, then the ending IP like: 192.168.100.1 - 192.168.100.255.
When nothing is filled in, then it must find my subnet and ping that, like when my ip is 192.168.100.6, it must ping from 192.168.100.1 - 192.168.100.255.
Yes I do have a script where the IP is already filled in, but not one, which knows in which subnet you are, to ping all of the IP adresses there...
How can I accomplish this?
Help is welcome!
