:r

Drops the file's extension and keeps the rest.

It cuts the final suffix — the .zip; a .tar.gz loses only the .gz — and returns the root of the name.

The classic use comes right after unpacking: the created directory usually carries the file's name minus the extension, and cd !$:r walks in without typing it.

$ unzip coleta.zip
$ cd !$:r
cd coleta

Of the file, the name of the directory it became.
