Even the most basic installation of any Linux distribution comes with a set of really useful utilities: “xargs” is undoubtedly one of those. By using xargs we can build and execute command lines using items from standard input as arguments of a command. To understand how to use xargs effectively, it’s important to note that this is especially useful when dealing with programs which don’t read standard input directly.

How to send desktop notifications using notify-send
Every desktop environment on Linux has its own notification system which implements the Freedesktop notifications specifications. Some of them, like GNOME or KDE, use their own built-in notification systems which cannot be replaced; others like Xfce or Mate, use more modular components (Xfce notification daemon and Mate notification daemon, respectively). Desktop-independent notification systems also exist (dunst, for example): most of the time they are used on minimal setups (e.g. when using a plain window manager instead of full blown Desktop environments).
journalctl command usage and examples on Linux
The journalctl command can be used to view all of the logs collected by systemd on a Linux system. This includes logs related to the system’s kernel, initrd, various services and applications, as well as systemd itself. The journalctl command makes querying all of these logs pretty painless, since systemd gathers and stores all these various logs in a central location for administrators to view.
Linux commands: Top 20 most important commands you need to know
There are thousands of commands that you can learn to use on a Linux system, but most users will find themselves executing the same few commands over and over. For users looking for a way to get started, we have compiled 20 of the most important Linux commands you need to know. These commands are some of the most useful, common, and essential tools that you will need in order to administer your Linux system or perform everyday tasks.
Bash base64 decode and encode on Linux
Linux commonly uses base64 to encode and decode data. This method of encoding provides a reliable way for data to be transmitted and stored. The encoding process will convert binary data to ASCII characters, making it usable by a variety of services (such as OpenSSL) that require readable ASCII character transmission as opposed to binary. Afterwards, the data can be decoded back to binary data. In this tutorial, you will see how to use the base64 command to decode and encode data on a Linux system.
Solving the ‘Command Not Found’ Error on Linux
While using the terminal of your Linux system, you will receive the Command Not Found error whenever a command you are entering is not accessible. In most cases, this could be due to a simple typo, or it could mean that you do not have the command installed yet. It could also indicate that the command is just missing from your system’s PATH environment variable, which is another easy thing to fix.
at command in Linux with examples
In Linux, you can automate many processes using various commands. You can even automate the process of running those commands. You can use the at command to run commands at a specified point in the future or it will only run these commands once. You can specify the time using key words like “tomorrow,” next week,” etc.
Linux shutdown commands explained
New users are often surprised by the number of commands that can be used to shut down a Linux system. Thanks to the flexibility of Linux and its storied history, there is almost always more than one – or more than a few – ways to accomplish the same task. Although Linux is always giving users plenty of choices on how to operate their system, one method usually proves better for certain scenarios, and all come with their pros and cons.
dd command in Linux with examples
Linux considers anything stored on a file system as files, even block devices. This means commands such as the dd command in Linux can be very handy in many situations, as it can be used to convert and copy files in the terminal, backup disks, or wipe data. The dd command is just as fundamental as it is useful, as it’s ready to use even on the most basic installations of Linux distros.

How to extract text from PDF document
PDF documents are commonly used to hold lengthy amounts of text, especially for formal matters like contracts or terms and conditions. These PDF documents can prove unwieldy in certain scenarios, since a PDF reader application is required to open them, and a PDF editor must be used for changing the contents.
