How to terminate a process forcibly in Linux?

In Linux, the kill command can be used to forcefully terminate a process. The basic syntax of the kill command is as follows:

terminate the process with the specified PID

Among them, the pid is the process ID of the process that needs to be terminated. The commonly used options of the kill command are as follows:

-9: Terminating a process using the SIGKILL signal is the most forceful way, as it will immediately end the process regardless of what it is doing.
-15: Ending a process using the SIGTERM signal is the default way, as it sends a termination signal to the process, which can choose to perform cleanup operations before exiting.
-2: Ending a process using the SIGINT signal is done by pressing Ctrl+C in the command line, and is typically used to interrupt a running process.

For example, to forcibly terminate a process with the process ID of 12345, you can use the following command:

Terminate process 12345 forcibly.

This will immediately terminate the process.
