That's brilliant. Now I need its compressing counterpart.

For compression, I have one for .tar.gz. But it's not that popular in my system. I need something a bit easier than 'pack file file file archive.tar.gz'

I use dtrx, which also ensures that all files are extracted into a folder.

`aunpack` does the trick for me.

Very nice and clean

Now, add inotify and a systemd user service and you would be getting somewhere. Also packaged versions of that exist already.

So, you created a square wheel, instead of a NASA wheel.

`tar xf` autodetects compressed files now. You can replace any of your instances of tar with that.

Yes, but only bsdtar has support for zip, rar, and 7z.

Honestly, it doesn't need any updates, it works so great without any pain, I'm just happy with it

Think this is the source https://justin.abrah.ms/bash/forgotten_friend_3.html

I had found a zsh version somewhere which I've updated a few times over the years though I don't get a chance to use it much. :'D
