  • Ripgrep – The Fastest Command Line Search Tool for Linux

    As the Linux operating system grows on you, you start being labeled the nerd you always wanted to be. Your behavior in this operating system environment changes completely. You develop a superiority complex that transforms you from a GUI-oriented user to a terminal-based user. You want to achieve a lot of things without switching between interfaces.

    ripgrep is one such tool that adaptively keeps a Linux user objectified and bound to the command line interface. It effortlessly achieves line-oriented recursive searches for a Linux user by adhering to regex pattern rules.

  • ROS2 On-Site Training: ROS2 Basics + ROS2 Nav2 + Manipulation with Movelt2 [Ed: ROS2 is Ubuntu GNU/Linux based]
  • Linux for Starters: Your Guide to Linux – Manipulating Files - Part 13 - LinuxLinks

    This is a series that offers a gentle introduction to Linux for newcomers.

    In Part 9 of this series we introduced the terminal, the shell and examined the four commands available in the shell: Builtins, aliases, external commands, and functions.

    In this article we take you through the basics of manipulating files from the shell. Some of these file manipulations are more conveniently done using a graphical file manager. But manipulating files from the shell offers both flexibility and power.

    The GNU Core Utilities or coreutils is a package of software containing implementations for many basic tools. This package provides the basic file, shell and text manipulation utilities. Specifically the package provides 96 separate external commands. We only need to cover 4 of them to explain the fundamentals of manipulating files. These commands are cp, mv, rm, and mkdir. Let’s look at each in turn.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
