Text Is the New Black


A few months ago a friend of mine got me setup with an account on his Linux box. This meant I had to relearn a ton of basic Linux commands I hadn’t used since high school. At first I was pretty frustrated. It was hard to get anything done. But I liked the idea of a slim development machine running in the cloud. One that I could leave on as long as I wanted. One that I could connect to from any machine (even and iPhone in a pinch). Since most of my development is just fancy text editing, I knew I had to step up me game.

Warning, generalization: a big epiphany for me as a programmer was understanding that all programs essentially start out as a bunch of text files sitting on a hard disk. There are a myriad of different file extensions, but most of them can still be opened with good old notepad++. Files that appear as a bunch of weird character typically mean that they have already been compiled and you need a special program to interpret them. Reason would follow that 20+ years of text based terminal systems would lead to pretty advanced tooling. Turns out that’s very true.

Anyway, let’s explore the things I needed to learn before I could be productive in a text only environment:


Step one was to learn Vim. Vim is a text editor that you can practically turn into an IDE. It’s modal, meaning that the same keyboard shortcuts do different things depending on what “mode” you are in. That is probably one of the biggest barriers to entry. What I didn’t realize was that Vim was the answer to all my problems with writing text, whether it be code or a blog post. In summary, if you want to be a text editing and code writing wizard, learn Vim. It’s worth every painful hour learning.

Tmux and SSH

If you’re using a mac, you won’t need to use SSH because OSX is built on Unix. Meaning you can run Unix commands and programs from the Terminal app. For us folks still stuck on Windows, we need to be able to remote into another machine running Linux; that’s what SSH is for. Once you are connected to a Linux box, you need something the manage your sessions. Tmux is a well know application for Linux that stands for “terminal multiplexer”. This is a fancy way of saying, “it manages multiple windows and keeps your sessions running even when you disconnect from the machine”. It does other stuff too, but those are the highlights. It’s hard to understate how much more productive Tmux makes you when working in a text environment. I tried using both GNU Screen and Tmux, I like Tmux much better. Here’s me using Tmux to write this post:

Look, I know this stuff is scary. I thought I’d never be able to learn it. But, with a bit of patience and perseverance, you’ll fall in love with the text way of life.
