How can I see history of the “at” command in AIX?
I'm experiencing a strange problem where occasionally the at command appears to not be running the command I've configured it to run.
For example:
at -t 201510071042
runsomescript
<Ctrl-D>
runsomescript does not run at 2015/10/07 10:42am, for some reason. Where can I see why at failed to run the command? I'm looking for some kind of log file for the at process.
Also, I am aware at sends mail. Having said that, I'm not getting an email either when at fails to execute the command.
If I run at -lov immediately after submitting the job, I see it in the queue to be ran at the appropriate time.
Additional info as of 2016-02-17
When the at command fails, mail contains the following "Cron Job Failure" message:
Cron: 0481-072 Cannot change to your home directory.

If you can re-test, check the return code from at ($?) as well as the output ofat -l(lower-case ELL) to see if your job made it to the queue. I assume that the contents of at.allow and at.deny are not changing in the interim?

the at.* files are in /var/adm/cron, which may require root privileges to see. If your jobs are being submitted, though, you're beyond that point. Next thing I wonder about is the shell that it's being run as -- bsh, csh, or ksh.

The at command mails you all output from standard output and standard error for the scheduled commands, unless you redirect that output.
So make sure you can send mail using sendmail, and make sure your script doesn't redirect errors (e.g. to /dev/null).
