A smart and nice Twitter client on terminal wrote by Python.

You just replace use Getopt::Long with use Getopt::Long::Complete and your program suddenly supports tab completion. This works for most/many programs.

The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user. Beware, though: What you are about to see is not particularly elegant. In fact, the TTY subsystem — while quite functional from a user's point of view — is a twisty little mess of special cases. To understand how this came to be, we have to go back in time.

I was going to write something like this myself (for an experimental fully automated continuous deployment pipeline using only open-source tools) but this looks promising so maybe I won't have to.

Here are a couple of quick tips for writing more robust shell scripts from my last 10 years of working with bash.

▁▂▃▅▂▇ in your shell.

Having become fed up with dealing with rpmbuild, spec files, debian control files, dh_make, debuild, and the whole lot, I automated my way back to sanity.

The result is a tool I call "fpm" which aims to help you make and mangle packages however you choose, all (ideally) without having to care about the internals of your particular native package format.

...

With FPM, you can specify dependencies, architecture, maintainer, etc. All from a simple command line, and never forcing you to learn the pain and suffering that can come with rpm spec files or debian package building.

youtube-dl is a small command-line program to download videos from YouTube.com and a few more sites. It requires the Python interpreter, version 2.x (x being at least 5), and it is not platform specific. It should work in your Unix box, in Windows or in Mac OS X. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.

The Linux kernel exposes a wealth of information through the proc special filesystem. It's not hard to find an encyclopedic reference about proc. In this article I'll take a different approach: we'll see how proc tricks can solve a number of real-world problems. All of these tricks should work on a recent Linux kernel, though some will fail on older systems like RHEL version 4.
