Summary 0001495: Exit status 0 for the at utility needs rewriting
Description The exit status 0 description for the at utility has two problems:

1. It does not cover the case where "at -l" with no at_job_id operands writes no output because there are no jobs to list.

2. It implies that if two or more at_job_id operands are specified, there only needs to be one valid ID among them for the exit status to be 0.

The suggested new text for exit status 0 is rather long-winded. Depending on the outcome of bug 0001492, an acceptable alternative might be to change it to just "Successful completion".

The CONSEQUENCES OF ERRORS section also has a problem in that it refers to "the job" (singular), but with -l there can be zero or more jobs, and with -r there can be one or more jobs. The usual rule about continuing with later operands should apply for these.
Desired Action On page 2479 line 79612 section at, change:
The at utility successfully submitted, removed, or listed a job or jobs.
to:
Neither the -l option nor the -r option was specified and a job was successfully submitted; or, the -l option was specified with no at_job_id operands and there were no jobs to be listed; or, the -l option was specified and all job listings were successfully output; or, the -r option was specified and all of the specified jobs were successfully removed.

On page 2479 line 79615 section at, change:
The job shall not be scheduled, removed, or listed.
to:
If neither the -l option nor the -r option was specified, the job shall not be scheduled. Otherwise, the default actions specified in [xref to 1.4 Utility Description Defaults] apply.
