Misleading error message with multiple names

Bug report

$ kn service update echo echo1 --image duglin/echo
requires the service name

Expected behavior

I would have expected either something like:

$ kn service create echo echo1 --image duglin/echo
'service create' requires the service name given as single argument

or for it to do the update on both services (I kind of like this option).

Steps to reproduce the problem

See above

It would be nice if the fix was global and not just for the update cmd

Good point and also related to #213 which we should tackle within the next 3 months.

But for this one I think passing one name for create makes a lot of sense since the command is not kn services create ... which would say many creates. if you want to create many services then you can easily issue command many times.

/assign @maximilien as I am doing a live recording showing how to contribute to kn and this could be easy. I think this can be solved by itself and then perhaps solve all kn ... create ... for other commands. Cool?

[duglin]

I can see an argument for 'create' being special and not allowing multiple
