Ready to see what’s new in Ubuntu 22.04? In this article, you will learn about all of the main differences between Ubuntu 22.04 Jammy Jellyfish and its predecessor, Ubuntu 20.04 Focal Fossa. We will also list some of the more subtle changes which may not be as noticeable at first, but serve to modify the new operating system under the hood.
The ability to get the temperature of a key component such as a CPU is important, whether you are gaming, overclocking, or hosting intensive processes on a critical server for your company. The Linux kernel comes with modules built in that allow it to access onboard sensors within the CPU. In this tutorial, you will learn how to access these sensors and get the CPU temperature on a Linux system.
There are a variety of tools that a system administrator can use to check and monitor the health of their Linux system. This would include not only the physical hardware, but also the software and how many resources are being dedicated to running the installed services. In this tutorial, you will learn several commands to check overall health of your Linux system from the command line.
The purpose of this tutorial is to show various methods on how to rename or replace white space in multiple files. Some tools on a Linux system may not work properly with files that contain white spaces, which would give some users motivation to replace the white space with underscores, for example. Manipulating files without white space is much easier, as you do not have to worry about escaping the file name each time.
LEDE/OpenWRT is a Linux-based operating system which can be used as an alternative to proprietary firmwares on a wide range of routers.
Installing it provides increased security, let us tweak our router and give us a wide range of software packages to install from the system repositories.
Installing packages is
very easy, thanks to the
opkg package manager, but often the available
space on common routers is quite limited. In this tutorial we will see how to
extend the available system space using an USB device.
Plymouth is an application originally developed by Red Hat and later adopted basically by all the most commonly used Linux distributions. The software runs very early in the boot process, and provides eye-candy animations which accompany the user until he is prompted to login into the system. When Plymouth is used, boot messages are hidden, although they can be visualized simply by clicking the
esc key. Some users, however, may prefer to visualize boot messages by default, and avoid any animation.
When we need to schedule a task on a Linux system we can use utilities like cron or systemd-timers. Various implementations of cron exist, but they have in common the fact that they run as a system service, and are designed to be used on systems which are always up and running, like servers. When we need to schedule a task on a desktop or a notebook, which are turned off more often, we can use anacron instead.
Many people find it useful to organize some of their most frequented applications as shortcuts on their desktop. This allows for quick launching of programs or custom shortcuts. Although most Linux systems rely on a sidebar app launcher or start menu, desktop shortcut launchers can allow you to open applications or websites super fast, since they live right on your desktop and make the targets only a click away.
The purpose of this tutorial is to show how to change the language in LibreOffice on a Linux system. Setting the language in LibreOffice will not only reflect changes in the menus of the application, but will also allow you to get auto correct recommendations in the target language, but these settings can be configured independently of each other. Follow the steps below to get started.
