While Linux distributions don’t suffer the ignominy of a blue screen of death, running processes (aka programs) do become unresponsive sometimes. If you run a web browser, media player, ebook reader, etc. on your Linux distribution, each of these is a different process, with a unique process ID and, traditionally, you need to issue a couple of different commands to find this ID and stop it.
Released under the MIT License, fkill is a cross-platform utility that can be used to interactively kill processes with ease. With fkill, we can scroll through a list of running processes and kill any of them by pressing the Enter key. We can also search through the processes by typing the name of commands / processes into the terminal and the output will be filtered to show any matching entries. This is a world away from how commands such as top are used to list processes via grep and a separate command is then used to kill the process using its PID.
Fkill is not available in Linux distributions out of the box. It’s also not available in the software repositories of most Linux distributions. However, its only dependency is the Node.js runtime environment, which you can easily install from the software repository on your distribution. You’ll also need the npm package manager, which too can be installed using the package management tool on your distribution.
How to Install Fkill in Linux
The following instructions work in Ubuntu or Debian and probably several other flavors as well.
1. Open a terminal window and update the list of repositories.
$ sudo apt update
2. Install Node.js and Npm Package Manager.
sudo apt install nodejs npm
3. Install fkill.
npm install --global fkill-cli
How to Use Fkill to Kill Tasks in Linux
Terminating a program with fkill is as easy as typing it at the command prompt, with no command line arguments required. Here are three main ways to use it.
1. Type fkill and navigate the menu. If you just launch fkill, you’ll be shown a scrolling list of all current processes. Select the process you want to kill and hit Enter.
You can use the arrows to navigate through the list or start typing the name of the process you are looking for (ex: “fire” for firefox) and you’ll see a list of matching processes appear.
2. Enter fkill [process name]. For example, you’d type fkill firefox to kill firefox.
3. Enter fkill [process ID]. If you know the process ID, you can kill it directly.
Unlike alternative commands such as kill, which supports sending many different signals to the process, Fkill can only be used to kill the process so it works just like kill -9.
