E464: Ambiguous use of user defined-command

:help E464

  Ambiguous use of user-defined command

There are two user-defined commands with a common name prefix, and you used
Command-line completion to execute one of them. |user-cmd-ambiguous|
Example: >
    :command MyCommand1 echo "one"
    :command MyCommand2 echo "two"
    :MyCommand

  Not an editor command

I have stared at this for a little while can someone throw a bone my way or offer a way to do this without resorting to visual mode?

Answer 1

G is a motion, not a range specifier. See :help range.

Answer 2

" vim has internal sort
:.,$sort

"if has numbers use
:.,$sort n

"to delete duplicated lines
:.,$sort u

" read :h sort
