OPTIONS
       In  addition  to  the single-character shell options docu­
       mented in the description of the set builtin command, bash
       interprets the following options when it is invoked:
...
       set [--abefhkmnptuvxBCHP] [-o option] [arg ...]
...
              -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 an  until  or
                      while  loop,  part of an if statement, part
                      of a && or || list,  or  if  the  command's
                      return value is being inverted via !.
