This script gives your shell hitpoints. You start with 3 hp. Every time you run a command that fails, you take damage. If you run out of hp, the shell exits.
# This replaces your PS1 with a command that counts hitpoints.
. functions.sh
The hitpoints are stored in a tmp file that gets cleaned up on exit. Bash trickery even ensures you don't take damage repeatedly from the same error.
Of course this system comes with an API, in case you're the kind of person who wants to extend this:
# Deals damage
shhp_damage [AMOUNT]
# Heals by the specified amount
shhp_heal [AMOUNT]
# Overheals (Zelda BOTW rules) by the specified amount, giving you extra hearts.
shhp_overheal [AMOUNT]
# Prints the current hitpoints
shhp_hp
I don't understand the question.
