Do you want to try the new Pantheon Desktop without waiting for elementary OS 6 (Odin)? Then here is the solution to do that by installing it on Ubuntu 20.04 LTS or Linux Mint.

Elementary OS 6 is the up coming version from the developers of this operating system, however, even it will be based on Ubuntu 20.4, still taking quite some time to get released. In such a scenario if you don’t want to wait, we can access its early builds to install on some existing Ubuntu 20.04 LTS or Linux mint.

Gzip is a common compression algorithm that allows you to compress a file while keeping the original file format, ownership, and timeline.

When you use the gzip command to compress a file or folder, it would have the same name as before, but with the extension.gz.

You may sometimes find errors while using any Linux operating system such as denied while editing a file. This is because of fewer rights on that particular file. Chown is usually abbreviated as “change ownership”, which means that the Chown is an instruction for changing the owner of a group of files and folders on Linux. Moreover, you need to modify the owner of a folder that holds all of the documents in certain situations. You might have to consume recursive chown, which is one of the choices of the chown instruction. Recursive means chown will be done for all documents in the specified directory, and also files and folders inside all sub-directories. You’ll discover how to recursively modify the directory and file authorizations while using the chown instruction in this guide.

You must have prior knowledge on how to list all the directories and folders that are residing in Linux systems. You may have used the “ls’ command to do this while working on any distribution of the Linux operating system. In this tutorial, we will be covering the topic of the process of listing only the files from a specific directory or folder in a Linux system. If you want to learn about listing files, go through each step of this guide.

Most of the time this question arises, how will you list the empty file and folders when you are working on the Linux-based operating system? Empty files and directories are those which have no data or sub-directories within them, respectively. If you want to learn how to do it, then this tutorial is meant for you. You have to go through each step defined in this tutorial to list the empty folders or files in the terminal. First, you must have sudo privileges of a Linux-based system to use it. After logging in from the system, you have to open the command terminal from the Applications. We will have a look at some of the examples for listing empty folders.

If you spend most of your time on the terminal, you might think to personalize its appearance by changing the configuration files. If you notice that there are two configuration files of bash shell in Linux, one is “.bashrc,” and the second one is “bash_profile” or “.profile.”

These files are hidden and cannot be displayed using “ls” only; therefore, use “ls -a” in the terminal to view these files.

Awk command is a powerful tool to process data. It gets input data, manipulates it, and gives results in standard output. Various operations can be performed on rows and columns of a file.
Knowing the essentials of the “awk” command is very important when it comes to processing data efficiently, and this post covers the key features of the “awk” command.

With TeX Live, the TeX Users Group has created the most extensive distribution of the TeX free typesetting system. Here we learn how to install Tex Live full distribution version on Ubuntu 20.04 LTS Linux.

Well, Tex Live has replaced the no longer maintained teTeX distribution and is most likely aimed at users who already have experience with DTP and the corresponding programming languages.

It comes with lots of features, such as the TeX Live helps users to prepare and edit texts for typesetting and printing. A large number of typographical rules can be set for this. TeX Live specializes in texts with complex content – the program can also handle tables, for example, and TeX Live is the measure of all things, especially when it comes to setting mathematical formulas.

Miniconda is a minimal and stripped-down version of Anaconda distribution. As the name implies, Miniconda contains only Conda package manager, Python and a small number of useful packages such as pip, zlib including their dependencies.

Miniconda is suitable for those who don't mind to install each package individually. It saves you not only the disk space but also avoids dumping a lots of unnecessary applications that you don't use often in your hard drive. For those wondering, Anaconda distribution automatically installs 1,500 packages that consumes around 3 GB disk space. If you use only a handful of applications, miniconda might be a good choice!

Confused about permissions in Linux? In this tutorial, I go over the basics of permissions so that you can understand how it works. We'll cover the permissions string and each element within it, what each individual section means, as well as how to change permissions.

“ls” is a basic command that any Linux user should know. The ls command displays basic information about files and folders inside the file system. It’s included in the GNU core utility kit which comes standard with all Linux distributions.

While using Linux operating system, multiple programs wait to be converted into a process for execution. When a program changes into a process, a lot of attributes are set that can be manipulated. For this, the Linux system provides a helpful tool to set or fetch real-time attributes of a process.

The “chrt” command is a part of a low-level Linux utility that is not only used to set attributes on runtime but also to change the scheduling policy of a process and set its priority. It uses the existing PID of any waiting program to set and retrieve a schedule of real-time attributes. Simply, the scheduler decides which process is executed by the CPU first when the “chrt” command changes its priority.

In scripting, we must break string data for a variety of reasons. Split is an integrated feature in many computer languages that divides every string of data into various pieces. However, bash lacks a built-in feature for splitting a string. To break any string value, there are many single and compound delimiters to be used. A variable IFS (Internal Field Separator) is being used to specify a particular delimiter for string division. In this guide, you will learn how to use various methods to illustrate the process of breaking a string value in bash using the $IFS.

Linux Operating system provides multiple tools to manage its system. One of the helpful tools in Linux is the “chage” command. From its name, the “chage” command is derived from the words “Change Age”, which is used to modify the information such as duration when to change password, make account status active or inactive, sets expiry date of the account, and sets a reminder to change the password through an alarm before user’s account will be inactive.

It is important to enforce users to modify the password after a certain period due to security reasons. If you’re an admin, then modified and updated information will be visible to you.

Performing date operation in shell scripting is very common especially performing scheduling tasks. But dealing with “date” in bash scripting is a tangling job. Bash comes with the “date” command that displays the date in various formats.

PyQt5 is a comprehensive set of Python bindings for Qt v5. It is implemented as more than 35 extension modules and enables Python to be used as an alternative application development language to C++ on all supported platforms including iOS and Android. Following below is a brief description to enable PyCharm 2021.1 to execute python scripts been written with PyQT5 bindings involved on AlmaLinux 8.3.

The command opens an administration console and an xterm to all specified hosts. Any text typed into the administration console is replicated to all windows. All windows may also be typed into directly.
This tool is intended for (but not limited to) cluster administration where the same configuration or commands must be run on each node within the cluster. Performing these commands all at once via this tool ensures all nodes are kept in sync.

Connections are opened using ssh which must be correctly installed and configured.

Extra caution should be taken when editing files as lines may not necessarily be in the same order; assuming line 5 is the same across all servers and modifying that is dangerous. It's better to search for the specific line to be changed and double-check all terminals are as expected before changes are committed.
