How to kill a process by its pid in linux

To kill a process by its PID (Process ID) in Linux, use the kill command followed by the PID. First, identify the PID using ps, top, or pidof. For example:

1. Find the PID:
   bash

   CopyEdit

   ps aux | grep process_name


   or

   bash

   CopyEdit

   pidof process_name

2. Kill the process:
   bash

   CopyEdit

   kill PID

3. To force kill if it doesn’t stop:
   bash

   CopyEdit

   kill -9 PID


Ensure you have the necessary permissions to kill the process. Be cautious when terminating critical system processes to avoid system instability
