This is a new series highlighting best-of-breed utilities. We’ll be covering a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides.
The Command Line Interface (CLI) is a way of interacting with your computer. And if you ever want to harness all the power of Linux, it’s highly recommended to master it. It’s true the CLI is often perceived as a barrier for users migrating to Linux, particularly if they’re grown up using GUI software exclusively. While Linux rarely forces anyone to use the CLI, some tasks are better suited to this method of interaction, offering inducements like superior scripting opportunities, remote access, and being far more frugal with a computer’s resources.
Like any operating system, a Linux machine is always running lots of programs. Some are essential for the operating system to run, others are invoked by users. These programs are known as “processes”. A process normally ends when a program is closed or not needed. However, sometimes a process can get “stuck”, potentially consuming globs of RAM and/or CPU cycles. If this happens, it’s best to manually “kill” the process.
The Linux operating system comes supplied with a utility that deals with this situation. It’s called kill, one of numerous essential utilities shipped with util-linux, a standard package distributed as part of Linux. One thing a newcomer to Linux learns quickly is that they’re never limited to a single way of performing a task. And killing processes is no exception. In this article, we’ll look at an alternative to kill. It’s called fkill. It’s billed as offering a quicker and easier way to terminating processes.
fkill is actually a cross-platform utility. Besides Linux, it also runs on macOS and Windows.
$ git clone https://github.com/sindresorhus/fkill-cli.git
$ cd fkill-cli/
$ sudo npm install --global fkill-cli
You’ll need Node.js installed on your system.
I haven’t checked how many Linux distributions provide a package for fkill, although it’s available in the Arch User Repository.
fkill is available in the Snap Store. Snaps work across Linux on any distribution or version. They let developers bundle dependencies and assets into a package, simplifying installs to a single standard command.
