@Zacharý trying to access Adám's directory listings? ;p

No. ;)

well, that's what you're attempting to do with these commands :p

Mostly, I was attempting to see if this was possible.

good luck shutting down TIO

it's heavily sandboxed

It's a challenge, I like that. (And if it's unlikely to happen, there's less risk of me screwing anything up)

I feel silly now.

@Zacharý Ping me when done so I can move all these to a "Try breaking TIO" room.

Eh, I'm done now. I'll just keep doing my ideas on TIO-bash until then.

@Zacharý Isn't it easier to modify what you've written (i.e. on tio.run) than to rewrite it all the time here?

Yeah, sometimes I do stupid things like that
