  • Linux/BSD command line wizardry: Learn to think in sed, awk, and grep

    As a relatively isolated junior sysadmin, I remember seeing answers on Experts Exchange and later Stack Exchange that baffled me. Authors and commenters might chain 10 commands together with pipes and angle brackets—something I never did in day-to-day system administration. Honestly, I doubted the real-world value of that. Surely, this was just an exercise in e-braggadocio, right?

    Trying to read the man pages for the utilities most frequently seen in these extended command chains didn't make them seem more approachable, either. For example, the sed man page weighs in at around 1,800 words alone without ever really explaining how regular expressions work or the most common uses of sed itself.

    If you find yourself in the same boat, grab a beverage and buckle in. Instead of giving you encyclopedic listings of every possible argument and use case for each of these ubiquitous commands, we're going to teach you how to think about them—and how to easily, productively incorporate them in your own daily command-line use.

  • How to use the Fetch API in JavaScript

    In web development you will often need to connect/communicate with other web servers to get information/data. For example, when signing up for a new account on some websites you will often see an option to sign up using your Gmail or other third party accounts. This enables you to sign up for a new account with just a single click instead of manually filling out the whole form. When you select the “sign up using a third party account” option then the application communicates with the third party application’s server and sends a request to access your information that is stored there. This request is sent through API which is a set of rules that govern how different applications or systems communicate with each other. In this article we will learn to use JavaScript to send such requests.

  • How to copy-paste on Ubuntu terminal

    In user-interface design and human-computer interaction, copy-paste are operations that provide an interprocess communication mechanism for moving data via the user interface of a system. The copy command duplicates the data and saves it to temporary storage (the clipboard). Then this data from the clipboard is pasted into the desired location. The copied data is accessible to any program that supports the functionality and allows itself to transfer data easily.

    You may need to write long commands or sentences obtained in a file or on the internet while working on the Ubuntu terminal. You can save your precious time by utilizing copy-pasting techniques rather than entering them word by word. Using the standard keyboard commands Ctrl+c and Ctrl+v, you may have copied and pasted text multiple times in your Ubuntu Graphical User Applications such as LibreOffice, Gedit, OpenOffice. However, you may be surprised to learn that many common keyboard shortcuts do not work in Ubuntu Terminal.

  • 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.
