Running a cron job automatically after server reboot
Learn how to set up a cron job that runs automatically after a server reboot using the @reboot crontab directive, rather than a specific day or time.
This article explains how to run a cron job automatically when a server restarts. For instance, you might want to execute a script or launch an application right after the server comes back online.
To achieve this, use the @reboot directive in the cron job. For example, the following cron job runs the start_application.sh script located in the user's home directory once after the system restarts:
@reboot ${HOME}/start_application.sh| Note Make sure to specify the full path to the file you want to run in the cron job. Alternatively, you can use Bash environment variables like ${HOME} and ${USER} to define the path. |
