Atq prints the queue of jobs that are waiting to be run at a later date. These jobs were created with the
at(1) command. With no flags, the queue is sorted in the order that the jobs will be executed.
If the -c flag is used, the queue is sorted by the time that the at command was given.
The -n flag prints only the total number of files that are currently in the queue.
If a name(s) is provided, only those files belonging to that user(s) are displayed.
