  • find mostly doesn't need xargs today on modern Unixes

    For usage with find, all of this is unnecessary on a modern Unix and has been for some time, because find folded this into itself. Modern versions of find don't have just the traditional '-exec', which runs one command per file, but also an augmented version of it which aggregates the arguments together like xargs does. This augmented version is used by ending the '-exec' with '+' instead of ';', like so: [...]

  • Linux fmt Command – Formatting Text on the Command Line

    The fmt command is a text utility included in the GNU Core Utilities. It was originally created to format email messages at the command line. However, it can be very useful for reading any text files in the terminal. Sure, modern terminals will wrap text to fit in the window. But they don’t wrap at a word, it could split a word right down the middle. This makes it hard to read and even harder to keep your place.

  • How To Install Observium on Ubuntu 20.04 LTS - idroot

  • 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.
