    Interesting solution! Clearly more elegant than kill $$. Commented Sep 19, 2012 at 9:23

    One thing to watch out for, this trap won't handle interpolated commands, e.g. echo "$(exit 77)"; the script will carry on as if we'd written echo "" Commented Mar 30, 2016 at 14:58
  • Interresting! Is there any luck on (quite older) bash that doesn't have -E ? maybe we have to resort to defining a trap on a USER signal and using a kill to that signal? I'll do some reasearch too... Commented Apr 6, 2016 at 18:44
  • How to know, when not being in a sub-shell trap, in order to return 1 instead of 77? Commented Nov 9, 2016 at 14:38
