Introduction The Linux operating system is based on a robust set of command line tools that allow users to easily manage and control the system. One of the most powerful and widely used command line utilities is the "diff" command. The "diff" command in Linux is used to compare the contents of two files line by line and show the difference between them. This command-line utility is essential for developers and system administrators to identify changes to code or configuration files. In this article, we'll take a closer look at the diff command and its various options and usage scenarios. ... Read More
Introduction On Linux, the "last" command is used to display a list of users who have previously logged in to the system.

Introduction File linking in Linux is a powerful feature that allows users to create multiple references to the same file. This can be useful in a variety of situations, such as when you want to link to a file or when you want to share a file across multiple directories. In this article we will discuss the different types of shortcuts that can be created in Linux and the commands used to create them. We'll also explore the differences between hard links and soft links, and when to use each type. Hard Links A hard link is a direct link ... Read More
Introduction Docker is a powerful tool that allows developers to easily build, deploy and run containerized applications. Containers are a lightweight and portable form of virtualization that packages an application and its dependencies, making it easy to move between different environments. The evolution of Docker began with Linux Containers (LXC) and has since revolutionized the way we think about software development and distribution. In this article, we'll explore the evolution of Docker from Linux containers, the benefits of using containers, and how Docker enhances the LXC concept. What are Containers? Containers are a logical packaging mechanism that extracts applications from ... Read More
Introduction Working with strings in Linux can be a bit tricky, but with the right tools it can be a piece of cake. A common task many Linux users have to perform is to check if a string contains a specific substring. This can be done using a variety of methods, including regular expressions, string manipulation commands, and programming languages like Python or Perl. However, in this article, we will explore one of the most popular and efficient methods to check if a string contains a substring in Linux, that is by using the special shell variable IFS (Internal Field ...
