I'm not sure how to interpret POSIX on this issue, although the exit code is
apparently incorrect in cases where "tmp" does NOT exist.
The following exit values shall be returned:
0
The script to be executed consisted solely of zero or more blank lines
or comments, or both.
1-125
A non-interactive shell detected a syntax, redirection, or variable
assignment error.
127
A specified command_file could not be found by a non-interactive shell.
Otherwise, the shell shall return the exit status of the last command it
invoked or attempted to invoke (see also the exit utility in Special Built-In
Utilities).
