How can I see what at jobs are scheduled. I don't mean using atq or at -l for the jobs, but rather what actual commands are scheduled? For example with at 1940 < at_script, once the job is submitted how do I match the job id to the actual command, ie at_script?

You can view the job by looking at the file it builds when you submit the at job. The job name is actually a file in /var/spool/cron/atjobs/. It sets up the job in the file so it's a bit more than just what you put in your input file.

This was what I submitted % at 0800am Aug 26 < myatjob
The file myatjob contains:
#!/bin/csh -f
# This is myatjob script
date


The job file contains:
