-e      Exit immediately if a simple command (see SHELL GRAMMAR above) exits with a non-
        zero  status.   The shell does not exit if the command that fails is part of the
        command list immediately following a while or until keyword, part of the test in
        an  if  statement,  part of a && or || list, or if the command's return value is
        being inverted via !.  A trap on ERR, if  set,  is  executed  before  the  shell
        exits.
