Add a way to negate the `filter` criterion. #4

Closed sharkdp closed 6 years ago

sharkdp commented 6 years ago

... in order to say something like find | filter --not is_dir

Some options:

add a --not/-n option to filter
provide a new command reject
Add a composition operator (:?) in order to write find | filter is_dir : negate.

In the same way, we should support a way to reverse the sorting order in sort_by. The best option seems to be to add --not/-n and --reverse/-r.
