On a Linux system, the need to find a string in a file can arise quite often. On the command line, the grep command has this function covered very well, but you’ll need to know the basics of how to use it. On GUI, most text editors also have the ability to search for a particular string.

How to remove repository using Flatpak
Flatpak uses remote repositories (usually just called “remotes”) in order to search for and download software. If at any point you decide that you no longer wish to download applications that come from a particular repository, you can always remove it from Flatpak. This will prevent Flatpak from querying the specified repo for future software searches and updates.
How to add repository using Flatpak
To get started installing software with Flatpak, you will first need to add one or more software repositories. Flatpak uses these repositories (“remotes” in Flatpak terms) to search for and install software from centralized locations. This behavior should seem familiar to Linux users, as it is exactly how traditional package managers work as well.
How to List all flatpak repositories
Just like traditional package managers, Flatpak relies on software repositories in order to download applications. Repositories are a necessary component of Flatpak as they allow users to install applications and dependencies from a central location. A repository contains a catalog of installable software and will provide future updates to the packages as needed.
How to update Flatpak application
Applications that have been installed via Flatpak, just like those from other sources, will occasionally need to be updated. The Flatpak service can be used to keep your installed applications up to date. In this tutorial, you will see how to update all your Flatpak applications either individually or all at once on a Linux system.
How to manage power profiles over D-Bus with power-profiles-daemon on Linux
Power-profiles-daemons is a free and open source project designed to handle system power profiles over D-Bus. The two major Linux desktop environment, GNOME and KDE Plasma, are nicely integrated with it, allowing the user to easily manage power profiles from their dedicated power manager interfaces, but it is also possible to switch profiles and retrieve information about them from the command line, using a dedicated utility.
How to mount partition with ntfs file system and read write access
NTFS stands for New Technology File System and is developed by Microsoft for use on their Windows operating systems. NTFS is not normally used on Linux systems, but has been the default file system on Windows for many years. Linux users are probably used to seeing drives with the ext4 file system, which is ordinarily the default and certainly the most widespread in the Linux realm.
Redhat Disable Firewall – start, stop, enable, disable
firewalld is the default firewall on Red Hat Enterprise Linux, and it’s enabled by default, but it’s possible to disable the firewall on Redhat, and you’ll also see how to check firewall status in Linux.
