21: .SH DIAGNOSTICS
22: Upon termination each command returns two bytes of status,
23: one supplied by the system giving the cause for
24: termination, and (in the case of `normal' termination)
25: one supplied by the program;
26: see
27: .IR exit (2).
28: The former byte is 0 for normal termination, the latter
29: is customarily 0 for successful execution, nonzero
30: to indicate troubles such as erroneous parameters, bad or inaccessible data,
31: or other inability to cope with the task at hand.
32: It is called variously `exit code', `exit status' or
33: `return code', and is described only where special
34: conventions are involved.
