If you want to schedule certain commands to be executed at some point in the future under linux, you can do so through the atd service. All linux systems provide this feature by default.

1. Before using linux atd service, first confirm whether atd service is enabled. You can check the running status of service by using "/etc/init.d/atd status" command.

Use the command "at now+2 minutes" to write a command to execute in two minutes. For example, after 2 minutes, execute the command to view the current time of the system.

3. The time format of the at planned task can be divided into "specific time date format [04:00 2014-01-18]","fuzzy word format [midnight, noon, teatime]","relative timing method [now + how much + time unit]"

4. Use atq to query the added at plan tasks.

5. Use the atrm command to delete the added unexecuted planned tasks in the format of "atrm task number", such as "atrm 4".

6. You can configure which user can use the at command by configuring it in/etc/at.deny and at.allow.
