Practical and theoretical aspects of software development
find, grep, sed, and awk.
I gave a lunchtime presentation on find, grep, sed, and awk. After the jump you’ll find the slides, and a bunch of links that were helpful to me.
Inspired by a similar post by Ben Boyter this a list of useful command line tools that I use. It’s not a list of every tool I use. These are tools that are new or typically not part of a standard POSIX command line environment.
We all know about GNU core utilities that comes pre-installed with all Unix-like operating systems. These are the basic file, shell and text manipulation utilities of the GNU operating system.
In this article, we will share a number of cool command-line programs that you can use in a Linux terminal. By the end of this article, you will learn about some free, open source, and exciting, text-based tools to help you do more with boredom on the Command line.
The problem is, I often want to use the same efficient key bindings I use while programming when I’m doing other tasks. I want to be writing an email or documentation and edit a code snippet in the same way I normally edit code. I want to manage Git repositories right from my editor without having to touch the mouse. I want to browse the web in my editor, so I can easily copy code examples and run them. I want to track my to-do lists and the amount of time spent on each task.
Filesystem Hierarchy Standard (« norme de la hiérarchie des systèmes de fichiers », abrégé en FHS) définit l'arborescence et le contenu des principaux répertoires des systèmes de fichiers des systèmes d'exploitation GNU/Linux et de la plupart des systèmes Unix.

The first time I heard about containers it was like – what? what’s that?
Is a container a process? What’s Docker? Are containers Docker? Help!
It’s no secret that configuration for OpenSMTPD changed a lot with version 6.4.0. Despite the fact that changes were announced long time ago and that many configuration examples have popped-up, my particular usage wasn’t covered(1). Namely: using OpenSMTPD with Dovecot and Rspamd as chained MTA.
The grep command is used to find patterns in files. This tutorial shows some of the most common grep command examples that would be specifically beneficial for software developers.
X.org X Server application is vulnerable to privilege escalation issue. X.org X Server application allows lower privileged user to create or overwrite file anywhere on system , including files owned by privileged users (ex. /etc/shadow).
The attacker needs to have active console session to exploit this issue.
OpenBSD comes with the vmm(4) hypervisor and vmd(8) daemon. Virtual machines can be orchestrated with the vmctl(8) control utility, using configuration settings stored in the vm.conf(5) file.

Bashrc file or .profile are the place where we put the initialization of the bash/zsh/fish shell, and lot’s of software want to add a line here, mainly to init some environment variable, or change path (BTW there is a feature to do that on OSX). The result is a bloated, unreadable file for init. So, let’s split it in several files.
You might not know it, but inside your Intel system, you have an operating system running in addition to your main OS, MINIX. And it’s raising eyebrows and concerns.
Mise en place de pare-feu/routeurs hautement disponibles avec CARP et pfsync + GRE et OSPF et IPSEC | Unix Experience
Nous allons voir dans cette article comment mettre en place de la haute disponibilité sur pare-feu en utilisant CARP et pfsync. Ensuite nous relierons deux sites par un tunnel GRE chiffré en IPSEC. Ce tutoriel est réalisé sous Virtualbox.

Did you think that OpenBSD is suitable only for firewalls and high-security servers? Think again.
