Set Desktop Wallpaper from Command Line on Mac

Whenever I need to accomplish a basic task that typically calls for interacting with a UI, I challenge myself to complete the task from command line. After all, most UIs are simply a mask over basic commands, especially when it comes to the operating system. Suddenly I feel like an automation or systems engineer! One […]

Mac Dark Mode from Command Line

One of the best professional decisions I ever made was switching to a dark text editor theme. I suffered from horrible headaches for years, partially caused by late night coding sessions with blindingly bright computer screens. Recently Apple implemented a dark OS theme which helps my eyes, and thinking in a command line state of […]

How to Change Animated GIF Speed

Comedians would tell you that timing is the most important part of any joke. The same could be said about animated GIFs; whether they’re used as a meme or to illustrate a process, the speed of an animated GIF can effect its effectiveness. With that idea in mind, I set about trying to figure out […]

How to Send an iMessage From Command Line

As somewhat of a recluse, believe me when I say that text messages, instant messenger, and iMessage have relieved me of loads of anxiety and wasted time with short, meaningless voice chat. It’s been a decade since these communication types have become popular so we’ve moved on from appreciate these technologies to trying to optimize […]

Replace Last Command in Shell

Whether I fat-finger a command or my MacBook Pro keyboard’s keys don’t want to respond like they should, I’m frequently misspelling commands.  What’s more frustrating is that many of these commands are long, taking making fixing theme time-consuming. Luckily a Twitter follower is looking out for me, providing me a quick command for fixing the […]

Download a YouTube Channel’s Videos

YouTube is an endless source of entertainment, be it stuff you’re proud to share you like or stuff you would rather others not know about (see: David’s history of watching old WWE Royal Rumbles).  I watch a lot of YouTube in hotels and on flights when I don’t have internet access, so I use youtube-dl […]

Turn Bluetooth On and Off from Command Line on macOS

Bluetooth has been a revelation in wireless technology: wireless mice, headphones, streaming devices, and a variety of home and office environments.  It goes without saying that wireless peripherals are so much easier to manage than wired counterparts, especially mice, that I usually have my MacBook’s bluetooth turned on. There are times, however, that I move […]

Mercurial: Mass Add and Remove All Files

While I much prefer git and the GitHub workflow, Firefox’s codebase (mozilla-central) is store in a mercurial repository.  There are tools that wrap mercurial so you can use a git-like interface, like git-cinnabar, but my philosophy is to learn the root tool so that I know what’s going on every step of the way.  Imagine […]

Change Mac Brightness from Command Line

Earlier this week I posted about how you can modify your Mac’s volume from command line.  Little command line scripts make me smile because I spend so much of my day in command line, and automation can be the key to productivity.  I next thought about modifying brightness from command line and I found out […]
