ohmyzsh

Oh My Zsh is an open source, community-driven framework for managing your zsh configuration.

Sounds boring. Let's try again.

Oh My Zsh will not make you a 10x developer...but you may feel like one.

Once installed, your terminal shell will become the talk of the town or your money back! With each keystroke in your command prompt, you'll take advantage of the hundreds of powerful plugins and beautiful themes. Strangers will come up to you in cafés and ask you, "that is amazing! are you some sort of genius?"

Finally, you'll begin to get the sort of attention that you have always felt you deserved. ...or maybe you'll use the time that you're saving to start flossing more often. 😬

Prerequisites

• Zsh should be installed (v4.3.9 or more recent is fine but we prefer 5.0.8 and newer). If not pre-installed (run zsh --version to confirm), check the following wiki instructions here: Installing ZSH
• curl or wget should be installed
• git should be installed (recommended v2.4.11 or higher)

Basic Installation

Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either curl, wget or another similar tool.

Method	Command
curl	sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
wget	sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
fetch	sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Alternatively, the installer is also mirrored outside GitHub. Using this URL instead may be required if you're in a country like China or India (for certain ISPs), that blocks raw.githubusercontent.com:

Method	Command
curl	sh -c "$(curl -fsSL https://install.ohmyz.sh/)"
wget	sh -c "$(wget -O- https://install.ohmyz.sh/)"
fetch	sh -c "$(fetch -o - https://install.ohmyz.sh/)"

Note that any previous .zshrc will be renamed to .zshrc.pre-oh-my-zsh. After installation, you can move the configuration you want to preserve into the new .zshrc.

Manual Inspection

It's a good idea to inspect the install script from projects you don't yet know. You can do that by downloading the install script first, looking through it so everything looks normal, then running it:

wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
sh install.sh

If the above URL times out or otherwise fails, you may have to substitute the URL for https://install.ohmyz.sh to be able to get the script.

Using Oh My Zsh

Plugins

Oh My Zsh comes with a shitload of plugins for you to take advantage of. You can take a look in the plugins directory and/or the wiki to see what's currently available.

Enabling Plugins

Once you spot a plugin (or several) that you'd like to use with Oh My Zsh, you'll need to enable them in the .zshrc file. You'll find the zshrc file in your $HOME directory. Open it with your favorite text editor and you'll see a spot to list all the plugins you want to load.

vi ~/.zshrc

For example, this might begin to look like this:

plugins=(
  git
  bundler
  dotenv
  macos
  rake
  rbenv
  ruby
)

Note that the plugins are separated by whitespace (spaces, tabs, new lines...). Do not use commas between them or it will break.

Using Plugins

Each built-in plugin includes a README, documenting it. This README should show the aliases (if the plugin adds any) and extra goodies that are included in that particular plugin.

Themes

We'll admit it. Early in the Oh My Zsh world, we may have gotten a bit too theme happy. We have over one hundred and fifty themes now bundled. Most of them have screenshots on the wiki (We are working on updating this!). Check them out!

Selecting A Theme

Robby's theme is the default one. It's not the fanciest one. It's not the simplest one. It's just the right one (for him).

Once you find a theme that you'd like to use, you will need to edit the ~/.zshrc file. You'll see an environment variable (all caps) in there that looks like:

ZSH_THEME="robbyrussell"

To use a different theme, simply change the value to match the name of your desired theme. For example:

ZSH_THEME="agnoster" # (this is one of the fancy ones)
# see https://github.com/ohmyzsh/ohmyzsh/wiki/Themes#agnoster

[!NOTE] You will many times see screenshots for a zsh theme, and try it out, and find that it doesn't look the same for you.

This is because many themes require installing a Powerline Font or a Nerd Font in order to render properly. Without them, these themes will render weird prompt symbols. Check out the FAQ for more information.

Also, beware that themes only control what your prompt looks like. This is, the text you see before or after your cursor, where you'll type your commands. Themes don't control things such as the colors of your terminal window (known as color scheme) or the font of your terminal. These are settings that you can change in your terminal emulator. For more information, see what is a zsh theme.

Open up a new terminal window and your prompt should look something like this:

In case you did not find a suitable theme for your needs, please have a look at the wiki for more of them.

If you're feeling feisty, you can let the computer select one randomly for you each time you open a new terminal window.

ZSH_THEME="random" # (...please let it be pie... please be some pie..)

And if you want to pick random theme from a list of your favorite themes:

ZSH_THEME_RANDOM_CANDIDATES=(
  "robbyrussell"
  "agnoster"
)

If you only know which themes you don't like, you can add them similarly to an ignored list:

ZSH_THEME_RANDOM_IGNORED=(pygmalion tjkirch_mod)

FAQ

If you have some more questions or issues, you might find a solution in our FAQ.

Advanced Topics

If you're the type that likes to get their hands dirty, these sections might resonate.

Advanced Installation

Some users may want to manually install Oh My Zsh, or change the default path or other settings that the installer accepts (these settings are also documented at the top of the install script).

Custom Directory

The default location is ~/.oh-my-zsh (hidden in your home directory, you can access it with cd ~/.oh-my-zsh)

If you'd like to change the install directory with the ZSH environment variable, either by running export ZSH=/your/path before installing, or by setting it before the end of the install pipeline like this:

ZSH="$HOME/.dotfiles/oh-my-zsh" sh install.sh

Unattended Install

If you're running the Oh My Zsh install script as part of an automated install, you can pass the --unattended flag to the install.sh script. This will have the effect of not trying to change the default shell, and it also won't run zsh when the installation has finished.

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended

If you're in China, India, or another country that blocks raw.githubusercontent.com, you may have to substitute the URL for https://install.ohmyz.sh for it to install.

Installing From A Forked Repository

The install script also accepts these variables to allow the installation of a different repository:

• REPO (default: ohmyzsh/ohmyzsh): this takes the form of owner/repository. If you set this variable, the installer will look for a repository at https://github.com/{owner}/{repository}.

• REMOTE (default: https://github.com/${REPO}.git): this is the full URL of the git repository clone. You can use this setting if you want to install from a fork that is not on GitHub (GitLab, Bitbucket...) or if you want to clone with SSH instead of HTTPS (git@github.com:user/project.git).

NOTE: it's incompatible with setting the REPO variable. This setting will take precedence.

• BRANCH (default: master): you can use this setting if you want to change the default branch to be checked out when cloning the repository. This might be useful for testing a Pull Request, or if you want to use a branch other than master.

For example:

REPO=apjanke/oh-my-zsh BRANCH=edge sh install.sh

Manual Installation

1. Clone The Repository

git clone https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh

2. Optionally, Backup Your Existing ~/.zshrc File

cp ~/.zshrc ~/.zshrc.orig

3. Create A New Zsh Configuration File

You can create a new zsh config file by copying the template that we have included for you.

cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

4. Change Your Default Shell

chsh -s $(which zsh)

You must log out from your user session and log back in to see this change.

5. Initialize Your New Zsh Configuration

Once you open up a new terminal window, it should load zsh with Oh My Zsh's configuration.

Installation Problems

If you have any hiccups installing, here are a few common fixes.

• You might need to modify your PATH in ~/.zshrc if you're not able to find some commands after switching to oh-my-zsh.
• If you installed manually or changed the install location, check the ZSH environment variable in ~/.zshrc.

Custom Plugins And Themes

If you want to override any of the default behaviors, just add a new file (ending in .zsh) in the custom/ directory.

If you have many functions that go well together, you can put them as a XYZ.plugin.zsh file in the custom/plugins/ directory and then enable this plugin.

If you would like to override the functionality of a plugin distributed with Oh My Zsh, create a plugin of the same name in the custom/plugins/ directory and it will be loaded instead of the one in plugins/.

Enable GNU ls In macOS And freeBSD Systems

The default behaviour in Oh My Zsh is to use BSD ls in macOS and FreeBSD systems. If GNU ls is installed (as gls command), you can choose to use it instead. To do it, you can use zstyle-based config before sourcing oh-my-zsh.sh:

zstyle ':omz:lib:theme-and-appearance' gnu-ls yes

Note: this is not compatible with DISABLE_LS_COLORS=true

Skip Aliases

If you want to skip default Oh My Zsh aliases (those defined in lib/* files) or plugin aliases, you can use the settings below in your ~/.zshrc file, before Oh My Zsh is loaded. Note that there are many different ways to skip aliases, depending on your needs.

# Skip all aliases, in lib files and enabled plugins
zstyle ':omz:*' aliases no

# Skip all aliases in lib files
zstyle ':omz:lib:*' aliases no
# Skip only aliases defined in the directories.zsh lib file
zstyle ':omz:lib:directories' aliases no

# Skip all plugin aliases
zstyle ':omz:plugins:*' aliases no
# Skip only the aliases from the git plugin
zstyle ':omz:plugins:git' aliases no

You can combine these in other ways taking into account that more specific scopes take precedence:

# Skip all plugin aliases, except for the git plugin
zstyle ':omz:plugins:*' aliases no
zstyle ':omz:plugins:git' aliases yes

A previous version of this feature was using the setting below, which has been removed:

zstyle ':omz:directories' aliases no

Instead, you can now use the following:

zstyle ':omz:lib:directories' aliases no

Notice

This feature is currently in a testing phase and it may be subject to change in the future. It is also not currently compatible with plugin managers such as zpm or zinit, which don't source the init script (oh-my-zsh.sh) where this feature is implemented in.

It is also not currently aware of "aliases" that are defined as functions. Example of such are gccd, ggf, or ggl functions from the git plugin.

Disable async git prompt

Async prompt functions are an experimental feature (included on April 3, 2024) that allows Oh My Zsh to render prompt information asynchronously. This can improve prompt rendering performance, but it might not work well with some setups. We hope that's not an issue, but if you're seeing problems with this new feature, you can turn it off by setting the following in your .zshrc file, before Oh My Zsh is sourced:

zstyle ':omz:alpha:lib:git' async-prompt no

Getting Updates

By default, you will be prompted to check for updates every 2 weeks. You can choose other update modes by adding a line to your ~/.zshrc file, before Oh My Zsh is loaded:

1. Automatic update without confirmation prompt:

   zstyle ':omz:update' mode auto

1. Just offer a reminder every few days, if there are updates available:

   zstyle ':omz:update' mode reminder

1. To disable automatic updates entirely:

   zstyle ':omz:update' mode disabled

NOTE: you can control how often Oh My Zsh checks for updates with the following setting:

# This will check for updates every 7 days
zstyle ':omz:update' frequency 7
# This will check for updates every time you open the terminal (not recommended)
zstyle ':omz:update' frequency 0

Updates Verbosity

You can also limit the update verbosity with the following settings:

zstyle ':omz:update' verbose default # default update prompt

zstyle ':omz:update' verbose minimal # only few lines

zstyle ':omz:update' verbose silent # only errors

Manual Updates

If you'd like to update at any point in time (maybe someone just released a new plugin and you don't want to wait a week?) you just need to run:

omz update

Magic! 🎉

Uninstalling Oh My Zsh

Oh My Zsh isn't for everyone. We'll miss you, but we want to make this an easy breakup.

If you want to uninstall oh-my-zsh, just run uninstall_oh_my_zsh from the command-line. It will remove itself and revert your previous bash or zsh configuration.

How Do I Contribute To Oh My Zsh?

Before you participate in our delightful community, please read the code of conduct.

I'm far from being a Zsh expert and suspect there are many ways to improve – if you have ideas on how to make the configuration easier to maintain (and faster), don't hesitate to fork and send pull requests!

We also need people to test out pull requests. So take a look through the open issues and help where you can.

See Contributing for more details.
