I am using `process.kill()` method of node.js. I am passing the process id of the process that I want to kill. I am getting the process id using `ps -aux | grep <filename>` command. This command gives the list of all the process that are running on the system. I am filtering the process that I want to kill using `grep` command. The command `ps -aux | grep <filename>` gives the following output:
