6 Exit Codes

Apart from issuing a descriptive error message, nssync attempts to indicate the reason of its termination by its error code. As usual, a zero exit code indicates normal termination. The table below summarizes all possible error codes. For each error code, it indicates its decimal value and its symbolic name from include/sysexits.h (if available).
