Well, when I finished this one I looked forward to your video to see how I could have solved this in a smarter way. I guess we all chose the rabbit 🐇 hole approach.

[@joeyshi2114]

Man! I hated how I needed to install several different packages for decompressing a zip file over and over again. This challenge drove me insane

[@iGarrettt]

Oh my zsh has an extract plugin wherein you just do "x filename" and it'll just figure it out and do it (in a lot of cases, anyway)

[@Daedalus-_-]

local man decompresses archives for 17 consecutive minutes

[@SteveMcKeon]

I can't believe how many times I expected it to be finished and it just kept going lol I was laughing pretty hard

[@viv_2489]

I'm surprised why this challenge had so many less solves....

[@drewzilla1263]

Great video series! I am learning a lot stepping thru these. I'm attempting them first and then coming here to watch your video. We basically had the same reaction at each step, as I'm sure many did.

[@Pallidum]

Well, this one for sure was a rabbit hole of nostalgia. Including a couple of variants I hadn't even heard of before.

[@LowPolySkull8303]

I remember pulling my hair out with that one. I thought it was going to be a never ending rabbit hole

[@gothops154]

You.. you don’t use an adblocker?

[@arey_yaar_yan]

Respect for going through the whole thing man!!!! That was a fucking nightmare to watch, can't imagine what doing that was like XD

[@rationalbushcraft]

cpio was the utility that we used to use in SCO Unix. I'm amazed that it is still around with the much better options we have today.

[@engelsteinberg593]
