At the beginning, I was not clear about the relationship between background processes, daemon processes, and cron processes. Now I understand. As I wrote in the text above: Background process: a program that does not require user input during running. Multiple background processes can be run on a multitasking operating system such as UNIX/Linux, while the user interacts with foreground processes such as data input ). Some background processes, such as

Linux tips: Scheduling jobs with Cron and atOn Linux systems, many administrative tasks must be performed frequently and regularly. These tasks include rotating log files to avoid filling the file system, backing up data, and connecting time servers to perform system time synchronization. The tutorials mentioned above describe these administrative tasks in more detail. In this article, learn about the scheduling mechanisms available in Linux, includin

Run tasks at any time through the Cron subsystem to easily implement routine maintenance To achieve continuous computation, the task must be able to run at any time.
