Once an "at" job is scheduled, we can see the time the job is scheduled for by running atq. This displays a unique job id along with scheduled time, but does not show the file or command name. One can look into the folder /var/spool/cron/atjobs and can do a cat on the file 'job id' to see which command is actually scheduled. All cron jobs can be found in /var/spool/cron/crontabs file.
