learn how to background and foreground a process to help you better multitask in the terminal ( Linux & macOS )
Most programs, when invoked from the shell, run in the foreground taking over your terminal and preventing you from doing other work without opening a new terminal window. But there’s a better way: bagrounding and foregrounding processes.
This works on both Linux and macOS, however there are slight differences. Here’s a simple example to help you understand how to background and foreground a process…

Powered by Linux, SpaceX successfully delivered NASA astronauts Bob Behnken and Doug Hurley into orbit
Even if you’re a macOS/iOS user or a Windows user, you are using Linux every single day. And you, probably, don’t even know it. How the hell is that even possible? Let me break it down for you. If you… :
… then you are using Linux.
On May 30, history was made when SpaceX’s Crew Dragon successfully delivered NASA astronauts Bob Behnken and Doug Hurley into orbit. What is less known about the event is that the launch was powered by Linux.
The Falcon 9’s onboard operating system is a stripped-down Linux running on three ordinary dual-core x86 processors. The flight software itself runs separately on each processor and is written in C/C++.
The Dragon spacecraft also runs Linux with flight software written in C++. The ship’s touchscreen interface is rendered using Chromium and JavaScript. If something were to go wrong with the interface, the astronauts have physical buttons to control the spacecraft.
However, SpaceX isn’t the first to bring the power of the open source kernel and software into the orbit. In 2013, the International Space Station reportedly switched from Windows to Linux. Not to mentions that NASA runs on Linux and even the Astrobee robots, that were deployed to the ISS not too long ago, run on Linux.

Probably the easiest way to install Arch Linux on your computer.
Arch is a fantastic Linux distro. From being a rolling release to its stability, to the Pacman package manager and AUR. Not to mention the Arch Wiki. However, the lack of a default GUI installer drives users away to other Arch-based distros like Manjaro and ArcoLinux.
But if you want to run pure Arch, you can either follow the installation guide or use an installer like Anarchy, Zen or ezarch. Let’s take a quick look at ezarch installation script….

Other than Arch-based distros, my favorite distro is Pop!_OS from System76. So, I’ve decided to install it on old laptop that was just laying around gathering dust. Superb release.
However, after spending a few minutes to customize it, I’ve noticed that even though YouTube videos play just fine in Firefox, other video streaming sites like Netflix or vimeo and even gifv embeds on Reddit return errors.
Luckily, there’s an easy fix….
SSHFS allows you to mount a remote filesystem using SFTP.
Maybe you need to work on remote projects, maybe you have multiple computers running different OS’ and you find yourself always going back and forth between them or maybe you just need to access a server. So how would you go about it?
You could use a cloud file hosting servive and sync everything across your computers, but depending on your needs that can get expensive. You could use an USB stick or external HDD/SSD, but if you run different OS’ with different filesystems that can quickly become an unnecessary headache. You can also use a FPT client like Filezilla but you can’t work on the remote filesystem unless you copy the file(s) on your local machine first.
If you don’t already have a system in place that works for you, you should take a look at SSHFS – a file system in user space that uses the SSH File Transfer Protocol (SFTP) to mount a remote file system.
