Just as a side note - the '&& true || false' part is redundant - the shell
evaluates && and || based purely on the last command's exit status;
so the '&& true || false' expression is only useful for turning
a "zero / non-zero" exit code into a "zero / one". In this particular
case, the last command is '[' a.k.a. 'test' - which in all its incarnations
I've seen so far returns zero or one.
