fkill

What is fkill?

The fkill npm package is a utility for forcefully killing processes. It provides a simple and user-friendly way to terminate processes by their name, port, or PID (Process ID).

What are fkill's main functionalities?

Kill a process by name

This feature allows you to kill a process by specifying its name. In this example, the 'chrome' process is terminated.

const fkill = require('fkill');

fkill('chrome').then(() => {
  console.log('Chrome has been killed');
});

Kill a process by PID

This feature allows you to kill a process by specifying its PID. In this example, the process with PID 1337 is terminated.

const fkill = require('fkill');

fkill(1337).then(() => {
  console.log('Process with PID 1337 has been killed');
});

Kill a process by port

This feature allows you to kill a process by specifying the port it is using. In this example, the process running on port 8080 is terminated.

const fkill = require('fkill');

fkill(':8080').then(() => {
  console.log('Process running on port 8080 has been killed');
});

Force kill a process

This feature allows you to forcefully kill a process. In this example, the 'node' process is forcefully terminated.

const fkill = require('fkill');

fkill('node', {force: true}).then(() => {
  console.log('Node process has been forcefully killed');
});

Other packages similar to fkill

taskkill

The taskkill package provides similar functionality to fkill, allowing you to kill processes by name or PID. It is more Windows-centric and uses the Windows taskkill command under the hood.

ps-node

The ps-node package allows you to search for and kill processes by name or PID. It provides more detailed process information and is cross-platform, but it requires more configuration compared to fkill.

kill-port

The kill-port package is focused on killing processes by port. It is simpler and more specialized compared to fkill, which offers a broader range of process-killing options.
