As a system administrator, you have to perform many important tasks such as updating and patching the servers, clearing old and unwanted log files, or backup your server and data. And often times, you can't perform these actions during a day time while it is being accessed by users. At that time, job schedulers are the best friends of any system administrator. Different Operating Systems provide different tools to run scheduled tasks. Windows OS comes with built-in Task Scheduler and you can install other third party applications as well. And most of the Linux distributions come with built-in job scheduling utility such as "Cron" and "Anacron". These tools work slightly differently in different distros. And in this video, we are going to see how can we install "Cron" and "Anacron"?, how to enable them during startup? and how to configure them to execute scheduled tasks both in Ubuntu and Red Hat Linux. #Linux #Cron #Anacron
