The time you spend staring at your terminal doesn’t have to be painful.

Practically without time or effort, you can transform your terminal from a frustrating white block of pain into a beautiful, fast, fun, easy-to-use seat of power.

The terminal is an incredible tool. It’s the magical box from which you can run your world. Why waste any more time using something that makes you less than thrilled?

When you first start your journey into coding, you’re quickly going to realize that you’ll be spending a LOT of time looking at the terminal. You might want to work as a programmer or developer, or you might be interested in artificial intelligence, machine learning, data science, or any number of other careers. No matter which of these paths you take, it’s a good idea to take a few minutes, get comfortable, and make your terminal a happy place.

If you’re using a Mac, new to programming, and completely resenting that blank white space, this one’s for you.

The preinstalled Mac terminal

If you have a Mac, you have a terminal window. Hooray! But even with some basic customization, this is probably not what you want to be staring at for large chunks of your day:

It’s there, it works, and that’s great. But with almost no effort at all, you can turn your terminal into something that you’ll be excited to play with. Something that will make your life so much easier.

Terminal vs. iTerm

You don’t have to use Terminal! There’s a hugely improved terminal called iTerm that’s much more customizable and has lots of cool features. You can search. You can split your panes. You have options for all kinds of things that you probably didn’t even consider doing.

Plus you can make it seriously sexy and much easier to work with hardly any effort at all!

Just head on over to the official site and then click the big button that says “Download.” After it downloads, open it up and install it just like you would anything else. (If you’re interested, you can find the download link for iTerm3 here.)

You’ll start with a terminal window that looks like this:

We’re just getting started.

Hush that login

You’re probably not totally loving the “last login” message that pops up when you open your terminal. Get rid of it by running this simple command in your terminal:

touch ~/.hushlogin

Grab some sweet downloads

It’s important to be aware that before your changes take effect, you’ll probably need to close and reopen your terminal.

If you aren’t seeing your modifications, close your terminal window and open a new one.

Homebrew

Homebrew is a great thing to have in your arsenal. They call themselves “the missing package manager for macOS” and they aren’t kidding. They install the stuff that you need that Apple didn’t install for you.

You can install Homebrew by running

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

It will pause and tell you what it’s up to while it’s installing. This thing is beyond useful and I can’t recommend it enough. Homebrew is a lifesaver.

Zsh

The default shell is bash, and that’s great if you want to keep it. But Zsh is more customizable and has a reputation for being faster. One of the coolest things that Zsh does is autocompletion. Any time you want, you can type something like “git c” and then press the tab key, and you’ll get a sweet little help window with autocomplete suggestions.

Also, Zsh has some seriously nice plugins that you really don’t want to miss. It comes preinstalled on a Mac, but the version seems to consistently be outdated, so you’ll want to run:

brew install zsh

Oh-My-Zsh

Do you like Zsh? You need to get Oh-My-Zsh! It’s an open source framework for managing your Zsh configuration that has thousands of awesome helpers and functions, plugins and themes. You can download it by running

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

Plugins

You can find a full list of official plugins here. They’re ready to go whenever you want. You’ll just need to enable them by adding them to your ~/.zshrc file. (Stay with me here. It’s easier than it sounds!)

To see what’s immediately available to you, head over to the plugins site. Scroll down and take a look at all of the plugins that you can install with practically no effort. You might want to add Git, GitHub, Python, Sublime, VSCode, or anything else that looks like it will make your life easier.

You definitely want Z.

It’s ridiculously easy to add plugins, but the directions might not make sense if you’re new to the terminal. When you want to make changes like this, you’ll need to edit your ~/.zshrc file. That sounds complicated, but it really isn’t! To open the file, run

open ~/.zshrc

That will open the text file that you need to make changes. Make sure you treat this file with respect. Changing something in here can and will make a big difference in how (and if) things work.

When you scroll through this file, you’ll see some things you can uncomment if you want to change them. You’ll also see spaces where you can add your own modifications.

Want to add or delete plugins? Scroll down to this part:

# Which plugins would you like to load?
# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git)

It’s like they want this to be easy!

Now add any plugins you want to use. For example, you might want to change that last line to

plugins=(git z github history osx pip pyenv pylint python sublime vscode)

Save it and you’re good to go!

Syntax Highlighting

You want Zsh syntax highlighting. It will tell you if your command is valid even before you run it. It’s handy.

To enable syntax highlighting, run

cd ~/.oh-my-zsh && git clone git://github.com/zsh-users/zsh-syntax-highlighting.git
echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc

and then enable it by running

source ~/.oh-my-zsh/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

Restart your terminal for your changes to take effect.

Z

Love Z. Love, love, love Z! Z takes it to the next level. It makes terminal life so much faster! To install it, run

brew install z

(Hopefully, you included Z in your plugins.)

Z is awesome. Z is smart. If you’re constantly typing something like:

cd this/is/the/path/to/the_file/ThisOne

now you’ll be able to type:

z thisone

and you’re there! You’ll need to do your normal thing for a bit while Z figures out what you like to do and then you’re off to the races.

Let’s say you’re always going to your “Repos” folder. Typing cd repos from just anywhere will never work.

But now you can just type z repos and jump right to it from anywhere!

Sublime Text

If you use Sublime Text as your primary text editor, you can make your life incredibly simple by setting up a Sublime shortcut. This way, any time you want to open a file with Sublime (or create a new file and open it with Sublime), you can use the command subl.

If you want to create and open a new file called “test.txt” in Sublime, you’ll type

subl test.txt

That will open Sublime and create a brand new text file called “test.txt.”

Here’s where I found the easiest way to get this working on a Mac with Zsh. First make sure you have Sublime Text installed and in your applications folder. To get it up and running, create a directory at ~/bin by running

mkdir ~/bin

Then run this:

ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/bin/subl

Now run this command to add a line to your ~/.zshrc file

echo 'export PATH=$PATH:$HOME/bin' >> ~/.zshrc

Then set Sublime as your default editor with this line:

echo "export EDITOR='subl' -w" >> ~/.zshrc

After you restart your terminal, you can test it with this:

subl .

That should open Sublime right up for you!

Let’s make it pretty

While there are a ton of themes you can use to modify the appearance of your terminal window, you might want to start simply.

Open iTerm and drop down the iTerm menu to “Preferences.” A window will pop up with lots of choices. You can pick the colors you like or use one of the options from the “Color Presets” dropdown menu in the “Colors” tab. You might want to choose a dark theme or make some other simple color choices. It’s easy to change the font and the font size under the tab that says “Text.”

You can also import a different theme any time you want. I’m using Atom for the color scheme, but you have a ton of choices. Take a look through this GitHub repository for examples.

If you want to install a custom iTerm theme, that’s simple. Just go to this GitHub repo and then hit either of the icons up at the top to download themes. (I went with the zip file. Once you download that file, click it to unzip it.)

Next, go to “Preferences,” click on the “Colors” tab, and click “Import” in the “Color Presets” dropdown menu. That lets you choose the color scheme you want. It will open up a finder window. Go into the “schemes” folder within the folder you downloaded and choose “Atom.itermcolors” if you want to use the Atom theme and click “Open.”

Now you can choose “Atom” from that dropdown menu!

If you want to change your font or font size, go to the tab that says “Text.” Then click the “Change Font” button to make your changes.

14 point Monaco just looks happy.

You can also easily adjust the transparency of your window. You might want to keep an eye on something that’s running behind your window. You might be new to programming and need to make sure you’re carefully following the tutorial you’re working through. It can be pretty helpful!

Just go to the “Window” tab, and adjust the slider under “Transparency:” until you’re happy.

Do what you wanna do.

Never forget: your playground, your rules. Make your space awesome! This just cracks the surface of what you can do. There are practically unlimited ways that you can customize your terminal.

Have some fun!
