My Terminal Setup: iTerm2 + Zsh 🔥

As a follow up to my post on my text editor setup, I wanted to write about the other key part of my development setup -- my terminal. Unlike my relatively new text editor setup, my terminal configuration has followed me around for years -- spanning over multiple jobs and even more computers. It's the first thing I get set up on when I get a new computer

The Terminal

I use iTerm2 for my Terminal emulator. It has some really cool features, like search, autocomplete, and paste history. That being said, the feature that makes it a complete must have for me is the split panes.

My Terminal

When I do web development work, I usually have panes open for my server session and for running other commands as necessary. When running many processes at a time, as was required at my old job, I would easily have 10 panes open at a time

Lot's of sessions

You can use the shortcut cmd + d for a new pane horizontally, and cmd + shift + d for a new vertical pane.

my terminal colors

I do have some tweaks to the color palette that I use -- I think the biggest is that my default font is pink (the forefront color).

Other than that, most of the "magic" comes from my shell, Zsh!

The Shell

For my shell, the programming language the command line uses, I use Zsh instead of Bash.

There are some pros and cons of using Zsh, the biggest drawback I've found is some difficulty installing certain software. This was a big learning curve at first, but over time I've gotten used to common stumbling blocks and don't have as many problems. Taking this into account, I would only recommend Zsh for experienced shell users!

That being said, the pros for me far outweigh the cons. The tab completion is much better in Zsh as compared to Bash. It even has tab completion for Git!

Oh My Zsh is a framework for managing your Zsh configuration, and it is a must download. When I refer to Zsh, a lot of the features are actually a part of Oh My Zsh.

My .zshrc

Instead of a .bash_profile, Zsh primarily uses a .zshrc file where your customizations are saved. By default, there are a bunch of comments explaining different settings in that file. I am going to go through some of my settings below.

Zsh has awesome themes, which change the appearance of your prompt.

I use Spaceship which displays a bunch of excellent information. For example, in the directory for my blog, which is a node app, my git branch, the git status, the package version, and the current Node version display. Also, it shows the amount of time the previous command took to run and the computer battery percentage if it is low! This changes slightly from directory to directory, but its really nice to have this information so accessible, especially compared to how difficult it can be to create something similar in a Bash environment.

I am always switching on and off the auto-correct built into Zsh. Right now I have it turned on, but it does sometimes annoy me.

ENABLE_CORRECTION="true"
Enter fullscreen mode Exit fullscreen mode

Another excellent Zsh feature is plugins. These make Zsh have better autocomplete for different languages or add additional features to the shell. I especially recommend the git plugin -- it's what gives you tab completion for git! I also really like zsh-syntax-highlighting. It highlights valid commands green and invalid ones red, so you don't even have to test the command to see if it will work!

plugins=(git node bundler osx rake ruby python javascript bash zsh-syntax-highlighting)
Enter fullscreen mode Exit fullscreen mode

After that, I have boring PATH and git configuration, so I'm going to leave that out.

Finally, we get to my aliases and custom functions. My guilty pleasure function that isn't great practice is entitled "acp". "acp" adds, commits, and pushes my code, and it looks like this:

function acp() {
  git add .
  git commit -m "$1"
  git push
}
Enter fullscreen mode Exit fullscreen mode

I use it way too much, but it really speeds things up when I'm working on personal projects.

I have two custom aliases setup:

alias groups="python ~/wdi/groupr/groupr.py"
alias zen="gatsby build && surge public/ zen-of-programming.com"
Enter fullscreen mode Exit fullscreen mode

The first creates random groups of my students for in-class activities and projects. Zen deploys my personal site. Yes, I only have two custom aliases; however, that is just because so many are built into Oh My Zsh!

Some built-in ones I rely on especially hard are "..." which is an alias for "cd ../..". You can keep adding periods and keep moving back in directories. You can also omit "cd" and just type the file name to change from one directory to another -- "blog" is equivalent to "cd blog." There are also other aliases built in to do almost anything you could dream of with git. I also enjoy please=sudo, even though I don't personally use it!

Another bonus utility I have on my computer is tree (which you can install on a Mac with brew install tree). This lists the folders and files in a directory in a really nice way.

I love oh-my-zsh!

Everyone loves their splitting, multiplexing terminals, but I tried something different this time—I’ve been using i3wm for almost a year, and I really like it. If I need a new pane, I just pop open a new tile.

I’ve never asked if there is a difference between the two. Am I missing out by not using a multiplexer?

On my Linux box I'm using Awesome WM, but it's the same principle. Why muck around with terminal panes when you have a whole window manager designed specifically for handling windows?

Bonus feature is that you can use any terminal you like without relying on it supporting panes/windows internally.

You typically also get multiple desktops with a window manager (called tags in awesome), so you can have a bunch of sysadmin terminals up on one tag and then either hit mod4+left/right to scroll to the next or hit mod4+number to jump to a specific one. I have mine set up to always open Firefox in a specific tag for example. You can configure different layouts for different tags, and swap layouts on the fly (awesome is a dynamic WM so it supports both tiling and floating windows).

Another bonus feature is it tiles/handles any type of window, not just terminals. So if you want two terminals, a gedit, and a browser up at the same time they all get tiled into the right place.

There's advantages of working in either way, but I'm looking forward to installing Awesome on my machine soon.
I think if you prefer to work on macOS Ali's way + a window management tool (BetterSnapTool is my favourite) is probably ideal.

Aside from feature sets, I really rely on love stories when picking out my dev tools.

oh-my-zsh! is one of those things I can't ignore the love for. I'm going to finally give it a dive.

I remember it being kinda slow. I'd recommend using zgen and loading only what you need from OMZ.

Yes - if you want to switch to a different session with a keyboard shortcut you have to use generic WM shortcuts and more importantly if you're on a foreign system and create a new terminal it'll be local. With a multiplexer it'll be logged into the remote system (and just as disconnectable as your original session)

This is super timely for me! I just started fiddling with my terminal last week for the first time (I'm just starting to learn to code.) I upgraded to iTerm and like some of the features already. I'll be saving this to return to and read as I start to understand more.

Does anyone have any recommendations on an article or video for total newbie programmers setting up their terminals? Maybe more of a high-level overview?

You're welcome!

The guy speaking is Jeffrey Way. One of the most advanced Laravel's users. He's even a Laravel contributor for what I know, along with Taylor Otwell who's the actual creator.

Btw, Laravel is a PHP framework (a pretty robust one tho!)
On Laracasts you can find a lot of videos on Laravel of course, but there are a lot of other topics that doesn't concern the framework and still can be very helpful.

Like: Git me some version control, or "stand back i'm going to try regex", vue2, flexbox etc.

Some free some under subscription. But still, the free material has the same quality as the paid one.

I love .oh-my-zsh and the plugins. Ie: git, sudo, z, colored-man-pages & dirhistory. I have used Konsole on Mint since 16 & now 19.

In case it's not clear, tree is not a shell built-in, it's the name of an external program (e.g. /usr/bin/tree.) Therefore it doesn't matter what shell you're using; either the program is installed or it isn't. Apt-get install tree, or brew install tree, or whatever other tool you use to install apps use that to install tree. ;)

Configured my terminal to look similar to the one in VSCode... Love it.

Great post!

I think it was oh-my-zsh which initially pushed me to really customize my own dotfiles. It's a good way to get a nice terminal setup really quickly and then you can tweak away from there.

Have you looked at kitty terminal? It's ridiculously performant, but requires conf file configuration.

Oh cool! I haven't noticed any performance issues with my current setup, but that could be an awesome option as well!

GPU based … does this mean I could do something cool with this dedicated graphics card I rarely turn on?

I’ve been using Termite for the last year. It’s easy.

GPU Rendering means it's really really fast. Some tests I ran went like this:

slack-files.com/T2ANEMZU1-FBT7X42E...

Alactritty: rg perl 7.28s user 28.04s system 21% cpu 2:43.80 total
iterm2: rg perl 7.15s user 26.87s system 0% cpu 58:14.69 total
kitty: rg perl 6.26s user 19.47s system 11% cpu 3:35.96 total
hyper: rg perl 6.65s user 16.02s system 25% cpu 1:27.68 total

So, things like tmux scrolling, vim scrolling, logfile scrolling are liquid smooth.

There's git tab-completion in bash as well if you turn it on.

I think that zsh has things to offer, but the things most people seem to talk about are available in bash if you want anyway. Zsh has some cooler globbing, but that's about it for me. I prefer to know bash well since it's much more likely to be the shell I'm using on a foreign system.

The only thing I miss since switching to Linux is iTerm2. Such a great piece of software... Well, at least I still have oh-my-zsh.

Thanks for sharing your setup!
