A repository for the most elegant and useful UNIX commands. Great commands can be shared, discussed and voted on to provide a comprehensive resource for working from the command-line

Many Linux users have experienced a lasting sense of accomplishment after composing a particularly clever command that achieves multiple actions in just one line or that manages to do in one line what usually takes 10 clicks and as many windows in a graphical user interface (GUI). Aside from being the stuff of legend, one-liners are great examples of why the terminal is considered to be such a powerful tool.

“What happens when you open a web browser and enter google.com?” Many of us recall being asked this question before. I think it leaves an impression because navigating web pages is this magical process that we take for granted. We do it hundreds, if not thousands of times per day without knowing how it works. Most developers and engineers can explain parts of it, but the depth at which you can discuss this question is infinite.

Today, we’ll discuss the details of something else we take for granted: the terminal. What happens when you open a terminal emulator and enter “ls”? Like with browsers, there is too much content to fit into one blog post. We’ll give you what we think are the interesting details.

Be more efficient with this Linux directory navigation trick.

fastmod is a fast partial replacement for codemod. Like codemod, it is a tool to assist you with large-scale codebase refactors, and it supports most of codemod's options. fastmod's major philosophical difference from codemod is that it is focused on improving the use case "I want to use interactive mode to make sure my regex is correct, and then I want to apply the regex everywhere".

askgit provides a sql interface to your git repository.

The Event Notify Test Runner is a general purpose Unix utility intended to make rapid feedback and automated testing natural and completely ordinary.

AWK is a text-processing language with a history spanning more than 40 years. It has a POSIX standard, several conforming implementations, and is still surprisingly relevant in 2020 — both for simple text processing tasks and for wrangling "big data". The recent release of GNU Awk 5.1 seems like a good reason to survey the AWK landscape, see what GNU Awk has been up to, and look at where AWK is being used these days.

Editly is a tool and framework for declarative NLE (non-linear video editing) using Node.js and ffmpeg. Editly allows you to easily and programmatically create a video from set of clips, images and titles, with smooth transitions between and music overlaid.

An introduction to shell productivity features: autocompletion, keyboard shortcuts, history navigation and shell expansions.

Fluency on the command line is a skill often neglected or considered arcane, but it improves your flexibility and productivity as an engineer in both obvious and subtle ways. This is a selection of notes and tips on using the command-line that we've found useful when working on Linux. Some tips are elementary, and some are fairly specific, sophisticated, or obscure. This page is not long, but if you can use and recall all the items here, you know a lot.

For bureaucratic reasons, a colleague of mine had to print, sign, scan and send by email a high number of pages. To save trees, ink, time, and to stick it.
