Yeah, this is bizarre. What fraction of apps actually use sysexits.h? 0.1%? 0.01%? If an application fails and exits with some >1 error code, it would be insane to assume it's following this convention. Hopefully the command's documentation describes the error codes (either referencing sysexits or explicitly listing the non-standard exit codes), and if it doesn't, you'll be stuck looking at the source code anyway.
