How to check CentOS version
The purpose of this tutorial is to show how to check the CentOS version of your Linux system. It’s possible to do this from either command line or GUI, so you can use whichever method is more convenient for you. Classic CentOS is nearing its end of life and will be replaced by CentOS Stream. Knowing your CentOS version will give you some insight into how long your system will continue to be supported.
How to run JAR file on Linux
JAR files are those that have been coded and compiled using the Java programming language. In order to run these files on a Linux system, the Java Runtime Environment (JRE) software must be installed first. This is just a software package that allows the system to understand JAR files, and therefore gives it the ability to open and run them. Usually, the JRE package is not installed on most Linux distros by default, so we must first install Java, and then we can open the JAR file(s).
How to change from default to alternative Python version on Debian Linux
Your Debian Linux installation may include multiple Python versions and thus also include multiple Python binary executables, and it’s possible to change the python version that the system is using. In this tutorial, you will see how to install multiple versions of python, and change the python version on Debian using the update-alternatives python command. This will allow you to run various Python programs including legacy scripts. Check the sections below to learn how.
Bash Scripting Tutorial
The Bash shell is one of the most powerful components of a Linux system, as well as one of the most compelling reasons to use Linux. Users can interact with Bash through the command line, and write scripts to automate tasks. Although this may sound intimidating to beginning users, it is not hard to get started with Bash scripting.
Linux: Install Java
Many developers and programmers choose to use a Linux system as their work environment because of its stability, speed, and ease of use. To get started with programming Java, or to simply run Java applications or applets on Linux, you will need to install the appropriate Java software package. Although this is pretty easy to do, the instructions will vary depending on a user’s Linux distribution, what version of Java they wish to use, and whether they need the JDK (Java Development Kit) or just the JRE (Java Runtime Environment).
How to write a Bash script to run commands

Whether you’re a beginner or an intermediate-level bash programmer, this article will provide you with the foundational knowledge and skills to create robust and efficient scripts that can automate even the most complex tasks.
Nested Loops in Bash Scripts
Nested loops in bash scripting are an essential tool for automation and efficiency when working with complex data structures, such as arrays and lists. By nesting one loop inside another, it’s possible to iterate through multiple levels of data with a single script, reducing the need for manual intervention and improving overall productivity. In this article, we will explore the basics of nested loops in bash scripts, including how to use them for various purposes, common errors to avoid, and advanced techniques for optimizing their performance. Whether you’re a beginner or an experienced bash scripter, this guide will help you master the art of nested loops and take your scripting skills to the next level.
Mastering Bash Script Loops
Bash script loops are an essential component of any developer’s toolkit for automating repetitive tasks and streamlining workflows. Loops in Bash provide a powerful and flexible way to iterate through lists, perform calculations, and execute commands based on specific conditions. By mastering Bash script loops, you can write efficient and readable scripts that save time and effort in managing complex systems and processes. This article will explore the different types of loops in Bash, their syntax and usage, and best practices for optimizing Bash loops for maximum efficiency.
Handling User Input in Bash Scripts
Bash scripting is a powerful tool that can automate various tasks on a Unix-like system. One crucial aspect of Bash scripting is handling user input. Accepting, validating, and processing user input is an essential part of creating robust and reliable Bash scripts. In this article, we will discuss various methods and best practices for handling user input in Bash scripts.
List of Python Escape sequence characters with examples
When programming in Python, escape characters can be used in order to tell the compiler that it should treat the next character or characters differently. For example, we can tell Python to print a quote " as an actual quote character, rather than interpreting it to be part of the Python code. Other special characters like \t can create TAB spaces, and \n can create new lines. In this tutorial, you will see a list of Python escape sequence characters and examples that you can use on a Linux system.
