actively. But if you use the-9 signal. Since the vi work will be forcibly removed, the. FILENAME.SWP will continue to exist in the file system. So you should be able to tell a little bit about it?In fact, the magical effect of Kill is very infinite! With Signal's detailed information (using Man 7 signal to access relevant data), you can effectively manage your work and programs (process), in addition. That Killall is the same way of using it. You need to know at least 1, 9, and 15 of the three

commands under Linux to control task jobs executionThe following commands can be used to manipulate process tasks:PS Lists the processes that are running in the system;Kill sends a signal to one or more processes (often used to kill a process);Jobs lists the status of tasks that are started in the current shell environment, and if JOBSID is not specified, displa

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 d
