available under MachTen.

Guide.
DIAGNOSTICS
Upon termination each command returns two bytes of status,
one
supplied by the system giving the cause for termination, and
(in
the case of ‘normal’ termination) one supplied
by the program, see
wait(2) and exit(2). The former byte is 0 for normal
termination,
the latter is customarily 0 for successful execution,
nonzero to
indicate troubles such as erroneous parameters, bad or
inaccessible
data, or other inability to cope with the task at hand. It
is
called variously ‘exit code’, ‘exit
status’ or ‘return code’, and
is described only where special conventions are
involved.
