How to find and kill a process in Linux?

To find and kill a process in Linux, you can use the following commands:

1. Find a process by name:

ps aux | grep process_name

2. Find a process and get its PID using the pidof command:

pidof process_name

3. Kill a process by PID:

kill PID

If the process does not terminate, you can use forceful termination:

kill -9 PID

4. You can also use the pkill command to find and kill a process by name:

pkill process_name

Example:

pkill -9 firefox

This will terminate all processes named firefox.
