To kill or terminate a Linux process, we can use the kill command. We need to kill the Linux process if it becomes unresponsive.
Below is the syntax of this command.
## Kill by using PID
kill <PID>
## Kill the process by using Name
kill <process_name>
Here, PID is the process Identification of the process that is being executed. We can kill a Linux process using two ways.
kill <pid>: This generates a signal SIGTERM allows the Linux process to be terminated gracefully by using the PID..kill -9 <pid>: This generates a signallSIGKILL which will forcefully terminate the Linux process by using PID.
| Signal | Number | Description |
| SIGKILL | 9 | It makes the process to exit without carrying out any routine tasks |
| SIGTERM | 15 | It causes the process to exit. But it allows us to close any files that are open |
| SIGHUP | 1 | It terminates the interactive process and programs in Linux |
| SIGCONT | 18,19,25 | It continues the process if stopped in between |
| SIGSTOP | 17,19,23 | It stops the process |
