Which command is used to display all user jobs that are currently scheduled to run as deferred jobs?

The command used to display all user jobs that are currently scheduled to run as deferred jobs is "atq." This command lists the jobs that have been scheduled with the "at" command, which allows users to run commands or scripts at a specified time in the future. When you execute "atq," it shows the job ID, the scheduled time, and the user who scheduled the job, providing a clear overview of what is pending.

This functionality is distinct from commands like "atrm," which is used to remove specific jobs from the queue, and thus it does not fulfill the requirement of displaying scheduled jobs. The "crontab -l" command lists user cron jobs, which are designed for repetitive tasks rather than one-time deferred jobs. Similarly, "anacrontab" deals with jobs that are meant to run at specific intervals but is not directly related to displaying one-time scheduled tasks. Therefore, "atq" is the appropriate command for retrieving the list of deferred jobs currently scheduled for execution.
