                          - Say I have this script:

        #!/bin/bash
             
        function cpp-lang {  
        yum install "Development Tools"  
        }
        function updatesys { 
        yum -y update 
        yum -y upgrade
        }
            
             whiptail --checklist "test" 5 40 5\
                        Update "Update the system" on \
                        C++ "Install C++" off 2>results 
        
        while read choice 
        do
              case $choice in
                Update )updatesys
                 ;;
                C++)cpp-lang
                 ;;
                 *)
                 ;;
                 esac
                 done < results

 When I run it, it exits, should I return something from the function? 

- Considering the script above as an example, should I run sudo every time I call yum install or is doing sudo ./script.shenough?
