(Optional) Configure the script to run only a single instance at a time:
(config system schedule script 0)> once true
(config system schedule script 0)>
If once is set to false , a new instance of the script will be started at every interval,

9. To run the script only once at the specified time:
(config system schedule script 0)> once true
(config system schedule script 0)>
If once is enabled, rebooting the device will cause the script to run again. The only way to re-
