> Grep is a powerful command-line tool that allows you to search for specific patterns or words in a file or group of files. It is widely used by programmers, system administrators, and analysts to search for specific patterns in logs, configuration files, and other types of data.
> One useful feature of grep is the ability to exclude certain words or patterns from the search. This can be useful if you want to focus on specific patterns or if you want to exclude certain types of information from the search results.
> Boost your productivity by automating your most frequent and monotonous tasks with Ansible.
> If you’ve ever tried to use the ifconfig command on a Linux or Unix-based system, you may have encountered the error message “ifconfig: command not found”. This error occurs when the ifconfig command is not recognized by the system, and can be frustrating if you’re not sure how to fix it.
> In this blog post, we’ll take a look at why the “ifconfig: command not found” error occurs and how to troubleshoot and fix it.
> Terraform is a powerful tool for building, changing, and managing infrastructure as code. It allows you to define infrastructure in a high-level configuration language, and then use those configurations to create and manage resources across a variety of cloud providers and on-premises environments. This article aims to detail a Terraform learning plan for those getting started with this great tool.
> Learning Terraform can be a valuable addition to your skill set, as it can help you automate the provisioning and management of infrastructure, making it easier to deploy and maintain applications and services. It is also a key tool in the realm of infrastructure as code, which is becoming increasingly important in modern cloud-based environments.

> In this tutorial, we will show you how to install VMware Tools on Ubuntu 22.04 LTS. For those of you who didn’t know, VMware Tools is a suite of utilities that enhances the performance of the virtual machine’s guest operating system and improves the management of the VM. It includes a number of tools, such as a virtual network driver to improve network performance, a time synchronization utility to keep the guest operating system’s clock synchronized with the host, and a utility to improve the display resolution and colors of the guest operating system.
> This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the VMware Tools on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
> Grep is a command-line tool that allows you to search for specific patterns or words in a file or group of files. It is commonly used by programmers, system administrators, and analysts to search for specific patterns in logs, configuration files, and other types of data.
> To use grep, you specify the pattern you want to search for and the file or files you want to search in. Grep will then output all lines that contain the pattern.
> Etcd is a free and open-source distributed and secure key-value store used to store the most critical information of a given distributed system. Etcd is written in Go making it extremely fast in distributed systems without incurring a performance overhead from clustered machines. In this guide, you discover the basics of installing and setting up an etcd cluster on Ubuntu systems.
> Dmidecode is a free and open source utility we can use to retrieve hardware information on Linux. The tool is available in the repositories of all the major Linux distributions, and is able to inspect and dump the content of the SMBIOS table.
> In this tutorial we learn how to install dmidecode, and how to use it to retrieve information about the hardware configuration on Linux.
> As a Linux administrator or a normal user, you often have to execute multiple commands in your terminal emulator like Gnome Terminal or Konsole for different purposes.
> But have you ever wondered which command you are executing repeatedly without being aware of it? So, don’t worry if this thought did not come to your mind before or until you found this article.
> In this article, you will learn how to find and list the most (including least) used commands in your Linux system.
> Hardly, 10 GB of disk space is used for the Linux operating system, and the rest of the space is occupied by your own files when you set up a new Linux system.
> Sadly, more disk space is consumed over time when your system gets cluttered with a lot of unnecessary files, mostly due to large log or backup files.
> However, you have the find and du commands that can help you estimate the file size in your current working directory or whole system, and by piping another command, you can list them based on their size.
> In this tutorial, you will learn how to find and list the largest files and directories in your Linux system using the “find” and “du” commands.
> Grep is a powerful command-line tool that allows you to search for specific patterns within text files. It’s a staple of many Linux and Unix-based systems, and is widely used by system administrators, developers, and others who need to search through large volumes of text data. In this article you will learn how to grep files recursively.
> One common use case for grep is the need to search through multiple files, including files within sub-directories. In this blog post, we’ll take a look at how to grep files recursively, including how to search through sub-directories, how to search for an exact match, how to only search within certain file extensions, and how to use the find command instead of grep.
