I've never trusted 'set -e' for anything other than simpleminded debugging, because set -e is a global setting (so it's inflexible) and it doesn't always work (so it's unreliable). For an example of the latter: set -e; { false; true; } && echo x This succeeds and outputs "x" even though the "false" command failed. (POSIX requires this and it's longstanding behavior.)
