atq

List pending jobs

$ atq

$ atq -u [username]

$ atq -q [a]

atq [-q queue] [-u user]

atq lists jobs pending in the at queue. It shows job numbers, execution times, and queue designations for scheduled one-time jobs.
This is equivalent to at -l.

-q queue

Show jobs from specific queue (a-z, A-Z)

Show jobs for specific user (root only)

Each line shows:
- Job number
- Execution date and time
- Queue letter
- Username

Non-root users can only see their own jobs. Jobs are lost if atd daemon is not running. Past jobs that couldn't run are shown.

atq is part of the at command suite, scheduling deferred command execution in Unix since the 1970s.
