Need Help With making this script

Shell Programming and Scripting
1

Hello, im a new user on this site and learning scripting very slowly at a understanding pace. However i am up with a challenge and require help completing this.

The script has to include arguments, variables, decisions and loops. So the script is about calculating the broadcast address for any given IP address and subnet mask...below is the layout of script details, Any help?

$ ./my_broadcast_calc 172.16.200.123/255.255.255.0


            172.16.200.255


 $ ./my_broadcast_calc 172.16.200.123/25


            172.16.200.255


 $ ./my_broadcast_calc 172.16.200.123/0xffffff00 -hex


            0xac10c8ff

The script should be able to handle the option �hex (which means display the final output in hexadecimal format). If the option is not provided, the the script should always display the result as in decimal (base 10) format.

Is this a homework assignment?

This is assignment from my course. The thing is i never learned how to deal with IP addresses in scripting :confused:

There is a separate forum for homework and I'm sure Don will fill you in on the rules around this.

As source of some related code have a look the following thread pinned on this forum:
