`cli-name` executable refers to non-existing Python module

Sorry about that... looks like something went wrong there. I created a cli command for easy commandline usage similar to pv but I totally forgot to finish it. I'll remove the command for now and re-add it once it's fully working.

Facing the same issue, any update ?

I'm working on a command that can be used as a drop-in replacement for the pv (pipeview) command with better output and some extra intelligence. A sneak preview of what it should roughly handle (if possible):

import argparse
import contextlib
import pathlib
import sys
import time

It won't be long, I promise :)

I've created a new release with a progressbar command that can be used as a drop-in replacement for pv or to replace cat as an automatic progressbar.

It can be used like this:

progressbar /dev/zero > /dev/zero

Or like this:

cat /dev/zero | progressbar > /dev/zero

If the filesize is available it will show a progressbar, if not, it will show a spinner like the regular progressbar would
