How can you prevent users from leaving a directory?

ls -lah

ctrl-D

I can think of a way out:

Just throw the whole PC away. It’s someone else’s problem now!

Does it have a perpetual energy source if I unplug it?

Combat the minefield with a fork bomb. Ain’t no process surviving this engagement.

\cd ~

Does it fry my hardware? Or can I just do another fresh install

i had a school colleague who could write small programs in bytecode, so i think someone who really knows their shit can get out without issues with cat and ls, as long as there isn’t much obfuscation

Maybe something like find ./ -type f | xargs md5sum, then avoid the one directory where the executable has a different checksum. Heck, even find | ls might suffice.

Based on the responses in this thread, I feel like you could present this screenshot with a “I bet you couldn’t find your way out of this!” and a zip of the directory, and a significant number of users would voluntarily download it and extract it just to “prove that they could”.

I wonder if we could bash -n -v the source code? 🤔 Since -n should error check without execution.

Edit: maybe that only works on scripts?

They never guess the next move: Unplugs pc

I’ll hit them with an rm /etc. We got out, we go out on together and on my terms.

Reminds me of gameshell, which is a rogue-like game designed to teach you the unix shell. So instead of navigating with NESW, you cd to locations. At one point you search the “garden”, which is an unmanageable tangle of directories, with find.

Reminder that binaries cannot change a shell’s working directory, so the non-mines will do nothing.

(cd is a shell builtin)

Has “let’s play a game” vibes

while this is not real, something similar in principal very much was! (but not too widespread)

see here or look up “casino dos malware”

uh in short it erases “the disk’s” (unsure which) file allocation table (pretty much the dos/windows version of a superblock). apparently some versions did copy it to memory and give the user a chance though!

The power cable would like to have a word.

We have squid games at home.
