which is correct?
function func_name() {
}
or
func_name() {
}

function func_name {
}

if put the plain test into hello file, then command hello prints. but if I make it a function, it returns nothing, but does not give error.

Consider, alias ls='ls -aF' as an example, this allow a user to essentially customise there POSIX Environment (Standardised UNIX Like Environment -- Linux is a KERNEL, not an operating system) without the need for external commands.

I think the author used bash shell as an example here, so it is BASH specific stuff. Best Regards, Mike Built-in command –> external commands.
