First, asking the same question more then once will not help your cause.

As to number 3; learn to use info for some of your answers I.E. info cp
will show at the end the you will get error message if the copy was
_not_ successful. Every copy is verified and if _not_ successful will
not complete. To compare two files use the diff command, info diff for
more information.
