Mission 30 & 31 Skipped

[ChefAharoni]

Right after completing mission 29, I was transferred to mission 32 due to a dependency issue. I am connected to internet, so not sure if the game attempted to download anything, but it was skipped immediately.
Could be useful to download those missing dependencies and move between missions to go back to incomplete missions.

Congratulations, mission 29 has been successfully completed!

The command 'pstree' is required for mission processes/03_pstree_kill/init.sh.

I'm running the game on my MacOS 15.4.1 (24E263) directly through the terminal, using zsh.

For security, simplicity and maintainability, I don't try to install / download anything.
So, if some dependency is missing, it is the user's responsibility to correct that and come back to the mission afterward.

I could add a sentence to the error message saying

If you install the missing dependencies, you can come back to the mission using
    gsh goto 30

And if you're asking about where to find the missing dependencies, you should be able to install everything Gameshell needs with

brew install nano pstree tree man-db wget

(Provided you use brew.)

I don't use MacOS, so I cannot test that thoroughly.
There should be only one (non-important) mission that you cannot do on MacOS because it depends on an X server and a specific X command. (mission 18 intermediate/04_bg_xeyes)
