1. Check NSH_NETINIT for self network initialization 2. Check NSH_ARCHINIT for sel arch specific initialization 3. Always show help regardless of NSH_BUILTIN_APPS 4. Loop forever regardless of NSH_BUILTIN_APPS, user could: a.change the default behavior by the command line argument b.or ctrl+c to break out the loop
