Doesn't 'exec' replace the process? I get the others (I think), but I don't understand what shell is left to "stop execution" after an exec.

`exec' can fail for various reasons: usually because the file to be
executed is not present or not executable.  In its default mode, an
interactive bash will not exit, while a non-interactive shell will.
The `execfail' shell option can be used to control the behavior in a
non-interactive shell.  Posix just says the shell exits if exec fails.
Previous versions once made a distinction between interactive and non-
interactive shells, which newer versions have dropped.
