The command "atrm" is used to remove one or multiple jobs from the "at" queue, which is a scheduler that allows you to schedule tasks and commands to run at a specific time in the future.
In this specific command: "atrm ${15} ${17} ${22}", the numbers inside the curly brackets represent job IDs. The command will remove three jobs with the IDs 15, 17, and 22 from the "at" queue.
Each time you schedule a job using the "at" command, it gets assigned a unique job ID. This is how you can refer to specific jobs when you want to remove or manage them using the "atrm" command.
