If you’re a Mac user, you know that Terminal is your go-to tool for performing various tasks. Whether you’re looking to change your wallpaper, fix a typo in a document, or just have some fun, Terminal is the perfect tool for the job. Here are some of the best Terminal tricks to get you started:
- Change Your Wallpaper If you want to change your wallpaper on your Mac, there are a few ways to do it. You can use System Preferences > Desktop & Screen Savers > Wallpaper and select a new image from the list. Alternatively, you can use the Terminal command “wallpaper -h” to get a list of all available wallpapers and choose one from there.
- Fix Typos in Documents If you find yourself making mistakes when writing documents, using Terminal can help! The command “typo” will show you all of the errors that have been made in your document so that you can correct them easily. You can also use “fix” to fix any typos that have been made in your document. Finally, if you want to make sure that all of your documents are error-free, use “checkdoc” to do an automated check on all of your documents before they’re published.
Some people find the macOS Terminal scary, and that makes sense. Commands can feel alienating, and learning to use them takes time. It’s hard to find a starting point.
We’ve shown you how to navigate using the Terminal, and a bunch of cool Terminal tricks, but it can all seem a little stale when you’re getting started. Isn’t there anything fun you can do with this text box?
Yes there is. Here are a few highlights to get started with.
Make Your Mac Say Anything Out Loud (In Siri’s Voice!)
Here’s a fun place to start: you can make your Mac say anything, out loud, with a quick Terminal command. Just type say followed by whatever phrase you want your computer to say.
The voice used depends on what you’ve chosen as the default voice in System Preferences > Accessibility > Speech. If you want it to sound like Siri’s iconic American voice, pick “Samantha.”
You can also specify which voice the command should use without changing the default, if you want to get fancy, by using the -voice option. For example, if you wanted to hear some text sung like a bell ringing, run say -v bells followed by your text. Note that you’ll have to install voices you want to use in System Preferences.
Finally, if you’re good with the Terminal, you can pipe the output of another command into say. Here’s a command that will get your Mac to state the current time, out loud:
Neat, isn’t it? Have fun thinking of other things to do with this.
Play Simple Games Like Tetris, Pong, and Snake
First, type emacs. This is going to launch the famous open source text editor, which you can learn to use if you’ve got a few years spare time.
For now we’re going to press Escape, followed by “X.” This will enable a text field for commands at the bottom on the screen.
Type tetris and hit Return. The game will launch.
Move the pieces with your arrow keys, and drop them with Space. It’s clumsy, but it’s a version of Tetris that came with your Mac.
You can launch other games from Emacs, too. Repeat the steps above, then type these words instead of tetris to launch alternative games:
pong: the classic line and pixel tennis game. snake: eat to become bigger, but don’t hit your tail. solitaire: not the card game. Instead, you need to hold Shift to jump pegs over each other. Can you win cleanly? dunnet: a simple text adventure game.
These are the main highlights, but there are a few more diversions. Here’s the official list, from the Emacs wiki. Let’s highlight one more in its own section.
Talk to a Virtual Therapist
This is technically an extension of the diversions above, but it’s too fun to skip. Follow the steps above, launching emacs then hitting Escape and X, then type “doctor.” Your computer will now play the role of a psychoanalyst.
It took a bit of conversation, but I eventually found the source of most of my problems in life.
Needless to say, your Mac is not a medical professional. Do not take medical advice from your Mac.
A Few More Commands
There are a few more things that, while not exactly “fun,” are neat for first-time Terminal users to discover. Here’s a quick list:
uptime will tell you how long it’s been since you last shut down your Mac. caffeinate will prevent your Mac from falling asleep, which is useful when you want a big download to finish during your lunch break. Oh, and you can hear a chime when you plug in your Macbook, like with the iPhone, with a single command.
There’s a whole lot more we could dig into, but the really fun stuff involves installing third party software. Our advice: set up Homebrew to install command line tools on your Mac, then check out our list of best command line tools you can get with Homebrew. You can do crazy things like listening to Pandora in your Terminal, so it’s well worth the effort.
