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?
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.

Mark the entry nasIP/nasPort as having ipaddress
rlm_ippool_tool -n session-db index-db ipaddress nasIP nasPort
Update old format database to new.
rlm_ippool_tool -u session-db new-session-db
DESCRIPTION
