Embedded Linux is an increasingly important field of technology that is used to enable the development of many products and services that are used in everyday life. For those wishing to pursue a career in embedded Linux, there are many opportunities available, ranging from entry-level positions to advanced roles. With the continued growth in the field, an embedded Linux career can offer a stable, rewarding, and exciting career path with plenty of opportunity for growth.

Linux DevOps is the practice of using Linux-based systems and tools to build, deploy, and manage applications in a continuous integration and continuous deployment (CI/CD) environment. This approach allows for the automation of many common tasks associated with software development, including source control, build automation, infrastructure orchestration, deployment, monitoring, and logging. DevOps also promotes collaboration between development, operations, and other IT teams, ensuring that applications and services are continuously monitored and optimized.

The Linux command line is a powerful tool used to control and interact with the operating system. It is a text-based interface that allows users to enter commands and execute programs, as well as view and edit files. The command line provides access to a wide range of Linux features and commands, including system utilities and applications, network configuration, file manipulation, and more.

A Linux Database Administrator is a technical expert responsible for the installation, configuration, maintenance, and security of database systems on Linux-based operating systems. They must have a strong knowledge of Linux operating systems and the database software they are managing.

XFS is a journaled filesystem originally developed by Silicon Graphics in 1993; it was released under the GPL license in the year 2000 and ported to the Linux kernel in 2001. Due to its high scalability and performances, XFS became the default filesystem in recent versions of Red Hat Enterprise Linux and its clones.

The Vim editor (and its predecessor, vi) is a command line editor for Linux systems. It has a long standing reputation as being the most powerful text editor on Linux. After mastering it, many users will even claim that it is far speedier and more convenient to use than a typical GUI editor packed with lots of features in its menus.

Vim has a staggering number of features and functions, but they are all hidden behind keyboard shortcuts and commands. There are no menus or hints in Vim, as users are expected to have enough of a grasp to navigate around on their own. And this is where Vim’s learning curve turns off most new users from bothering with it. Many novices would rather stick with something simple, like nano, than deal with all Vim’s depth.

On Linux-based operating system the /etc directory is used to hold global configuration files for applications and services. A good set of configurations is really important for a good working system, so being able to keep track of changes and quickly revert them, in case something go wrong, is crucial. Etckeeper helps us achieve this goal keeping configuration files under version control.

If you want to retrieve stock quotes and crypto price data, you do not even need to leave your command line terminal. In this tutorial, we will show you how to use a Bash script to get stocks and crypto pricing on a Linux system.

DAAP server is an Apple Inc. proprietary protocol to share media files over the network. DAAP server allows share media files among network connected devices where the central media share repository resides on main server. In this simple tutorial we will be installing and configuring DAAP server share using forked-daapd media server with support for RSP, DAAP, DACP and AirTunes on Ubuntu Linux or any other Debian Linux based system.

There is no need to install tons of software in order to create a nice and informative presentation. tpp, which stands for Text Presentation Program is a simple to use command line presentation tool which allows you to create a fancy text based slide show presentation and share it with your colleagues or students as an ordinary ASCII text file. tpp utilizes ncurses, and it supports colors, slide-in, source code output, animated command line execution and a real time command executions all available from within your terminal.

The ability to automate tasks with Bash scripts in Linux is one of the operating system’s most powerful components. However, due to the sheer amount of scripting components, it can be intimidating for newcomers. Even longtime users may forget something every once in a while and that is why we have created this Bash scripting cheat sheet.

If you have any experience on the Linux command line, then you should have run into command flags, which help us modify the behavior of a command that we are executing.For example, if we execute the ls -l command, the -l part of the command is a flag that we are passing as an argument to ls. This same functionality can be used in a Bash script, allowing us to pass some input to the script through flags when we are executing the script.

Normally, a Bash script will execute each line of code the moment it reaches it, then immediately move on to the next. But it is also possible to add pauses to a Bash script in order to delay it or allow the user time to respond to a prompt, etc.

UEFI is the firmware interface which on modern machines has superseded the legacy BIOS. One of the features of the UEFI firmware is being able to store boot entries in the persistent and editable NVRAM memory (Non Volatile RAM). While installing a Linux distribution (or any other operating system) in UEFI mode makes usually the related boot entry to be written to the NVRAM, in some cases we may want to perform manual operations such as modifying the boot order, creating or deleting a boot entry.

A loop device is a pseudo-device which doesn’t correspond to a real, physical block device, but can be used to make a file appear and be treated like one. To manage loop devices on Linux, we can use the losetup command: the utility let us create new loop devices, detach them and retrieve information about existing ones.

Qcow2 is the default virtual disk storage format used by Qemu (qcow stands for qemu copy-on-write). This image format makes use of thin provisioning, so, after we initially set the maximum virtual size of a disk, space is actually allocated only when used, but not made available back to the host when freed.In this article we see how to “sparsify” a qcow2 disk image to reclaim available space, how to expand it or shrink it, and how to manage the partitions layout on it from the host system, connecting it by using the NBD protocol.

In a previous article, we saw how to create kvm virtual machines from the command line; in this tutorial, instead, we learn how to access and modify virtual machines disk images, using some utilities which are part of the libguestfs package on the most commonly used Linux distributions. Those tools let us perform a variety of tasks.
