When to use the ‘at’ utility
The at
utility is best used for scheduling one-time tasks to run at a specific time in the future. Here are some scenarios where at
is particularly useful:
- Delayed Execution: Running a command or script after a certain delay without needing repeated execution.
- System Maintenance: Scheduling maintenance tasks like backups or updates during off-peak hours.
- Reminders: Sending reminders or notifications at a future time.
- Resource Management: Running resource-intensive tasks at a time when system usage is low.

echo "echo 'Backup complete'" | at 2am
This schedules a one-time task to echo “Backup complete” at 2 AM.
