    How to Run a Shell Script in Linux With Some Essentials Explained for Beginners

    Danie van der Merwe · / gadgeteerza-tech-blog · Yesterday - 18:47

Ever wondered why there is a ./ prepended to a shell script when executing or why you see #! /bin/bash at the start of shell scripts? This short article helps explain that.

The more one gets to understand why and how things happen in Linux, you start to realise how incredibly powerful it is. I'll still look out for an article on "why everything in Linux is a file" as that is another eye-opener.

    Kbackup – La sauvegarde facile sous Linux / Korben · Yesterday - 08:00 · 1 minute

Issu de l’univers KDE, Kbackup est un logiciel de sauvegarde libre que vous pouvez installer sur n’importe quelle distrib Linux (Ubuntu, Debian, Arch, Fedora, OpenSuses…etc) qui vous permet très facilement de conserver une copie exacte de votre répertoire /home/ sur autre disque dur ou clé USB.

Ce n’est pas compliqué à utiliser, moins cool que Rsync, mais totalement noob-user friendly, et c’est ça qui est bon !

Kbackup est très basique, mais également très rapide. Vous cochez les dossier à sauvegarder, vous choisissez un disque de destination (une clé usb par exemple) et vous cliquez sur le bouton « Commencer la sauvegarde « .

Et voilà ! Rien de plus à faire. La sauvegarde se fait de manière incrémentale, mais vous pouvez la forcer en mode « complète » si vous le désirez.

Et vous pouvez également créer différents profils, spécifier une taille max, exiger la compression des fichiers, étaler votre sauvegarde sur plusieurs supports ou encore exclure certains types de fichiers.

Dans le même style, je vous invite également à jeter un oeil à Borg Backup , RClone , TimeShift ou encore à Rsync et Backup Manager pour ceux qui aiment la ligne de commande.

    Explore binaries using this full-featured Linux tool / · 3 days ago - 08:03 edit

In 10 ways to analyze binary files on Linux , I explained how to use Linux's rich set of native tools to analyze binaries. But if you want to explore your binary further, you need a tool that is custom-made for binary analysis. If you are new to binary analysis and have mostly worked with scripting languages, 9 essential GNU binutils tools will help you get started learning the compilation process and what constitutes a binary.

    Why you need to drop ifconfig for ip / · 3 days ago - 08:00 edit

For a long time, the ifconfig command was the default method for configuring a network interface. It served Linux users well, but networking is complex, and the commands to configure it must be robust. The ip command is the new default networking command for modern systems, and in this article, I'll show you how to use it.

    Configure a Linux workspace remotely from the command line / · 6 days ago - 08:02 edit

One of the things I appreciate about Linux versus proprietary operating systems is that almost everything can be managed and configured from the command line. That means that nearly everything can be configured locally or even remotely via an SSH login connection. Sometimes it takes a bit of time spent on Internet searches, but if you can think of a task, it can probably be done from the command line.

    Corellium got Ubuntu Linux running on M1 Macs—and you can, too / ArsTechnica · 7 days ago - 18:07

For the first time, users of Apple Silicon Macs using Apple's M1 chip—such as the entry-level 13-inch MacBook Pro, Mac mini, and MacBook Air—can now boot in to and natively run Linux.

The vintage at play here is Ubuntu, and the port was developed by Corellium, which otherwise virtualizes iOS and other ARM-based OSes to enable easier security testing. It's worth noting as well that Apple has previously sued the company over said iOS security testing tool. The lawsuit didn't go Apple's way .

Corellium Chief Technology Office Chris Wade announced the culmination of the team's work on Twitter yesterday . And in a blog post on Corellium's website, the team behind the port writes that it was developed in parallel with the group's efforts at "creating a model of the [M1] for our security research part."

    How to Install Docker on Ubuntu 20.04 LTS (Beginners Guide)

    Danie van der Merwe · / gadgeteerza-tech-blog · 7 days ago - 09:00

Ever had that issue with some dependencies clashing with others, or missing dependencies either stopping an installation or an application from running properly? Upgrades for applications also can run into similar issues. More and more excellent self-contained options are appearing, but Docker has been around a while and there are numerous images ready for instant use as well as easy updating. This is the simplest guide I've seen so far, and I hope it has some future editions being published. For too long I avoided Docker because I just did not bother to understand it.

Containers contain everything an app, tool or service needs to run, including all libraries, dependencies, and configuration files. Containers are also isolated from each other (and the underlying host system), but can communicate through pre-defined channels.

    Convert your Windows install into a VM on Linux / · 7 days ago - 08:02 edit

I use VirtualBox frequently to create virtual machines for testing new versions of Fedora, new application programs, and lots of administrative tools like Ansible. I have even used VirtualBox to test the creation of a Windows guest host.
