It would be nice if the instructions spelled out what to do, then I could do it. Otherwise I have to guess what author meant. But all in, a nice small exercise, thanks!

Neat idea à la regex golf.

But doesn’t seem to do enough shell escaping or correctly. Also seems underspecified, ie “find 5 lines starting with ‘the” doesn’t require a pipe to head -5.

I tried to grep for "♫ piping ♫" at some point and the website got stuck. I wonder what it was trying to do...

other than that - nice exercise for newbie shell dabblers :-)

I would love something like this that puts me in my own shell. Like a light CTF that is really just shell commands rather than breaking into a VM

That's a nice little challenge.

I did have some issues with Day 11 figuring out what it wanted, but overall it was fun.

If you like things like this you'll probably enjoy

     b64(r13(MaE3o3OmYz5yqPNtqUu0VPOxnJpX))

Not giving real output is a complete fail. Try again.

Tab complete is completely broken on Firefox mobile (Android)

Cool idea but very opinionated and no room for variation

I assumed this was some kind of hacking challenge.
