What is the method of terminating a process in Linux?
In a Linux system, there are several methods available to kill a process.
- The kill command can be used to send a signal to a specific process in order to terminate it. By default, the kill command sends a SIGTERM signal. To kill a process, you can use the following command:
kill - Kill all command – This command allows you to terminate all processes with the specified name. Use the following command to kill a process:
killall
- Use the pkill command: similar to the killall command, it can kill processes based on their names. Use the following command to kill a process: pkill
- To forcefully terminate a process that cannot be killed through normal means, you can use the command kill -9. This will send a SIGKILL signal to the specified process, causing it to immediately terminate. To kill a process, use the following command: kill -9
. - By using System Monitor or Task Manager, graphical interface tools can provide a more intuitive way to terminate processes. Depending on the Linux distribution and desktop environment you are using, you can open the corresponding system monitor or task manager program, locate the process to be terminated, and then choose to terminate or end the process.
It’s important to note that when using the kill command, killall command, and pkill command, you need to have the appropriate permissions to terminate processes of other users. However, when using the kill -9 command, you can forcefully terminate any process, but it may result in data loss or other issues, so it should be avoided as much as possible in normal circumstances.
