!:n-
From the nth to the next-to-last — drops the final word.
A range with an open end: it starts at word n and stops before the last. It's the designator for when the destination no longer matters.
After moving a list of files into a directory, !:1- is the list without the directory — ready for the next command.
$ mv prensa-01.jpg prensa-02.jpg ./arquivo/
