Zsh / Oh-my-zsh on Windows Git Bash

install-zsh-windows-git-bash.md

Steps:

1. Download the latest zsh package: https://packages.msys2.org/package/zsh?repo=msys&variant=x86_64

Example:

zsh-5.7.1-1-x86_64.pkg.tar.xz

Update:

The package now is compacted using zstd, so now we need some "special" extractor.
So, in my case, I've downloaded this file
https://repo.msys2.org/msys/x86_64/zsh-5.8-5-x86_64.pkg.tar.zst And extracted it using the Peazip.
https://peazip.github.io/zst-compressed-file-format.html

2. Extract the content to your git bash installation dir:

Usually C:\Program Files\Git

3. Test it and config zsh:

Open git bash and type:

zsh

So, this step is important, it seems zsh will ask a few configurations, like the tab completion, history, etc.
Please read the options and set that according to your use.

4. Installing oh-my-zsh, execute the following cmd on git bash

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

5. Configuring zsh as default shell

Edit the ~/.bashrc file. (create it if it doesn't exist)

Add the following lines at the end of the file

# Launch Zsh
if [ -t 1 ]; then
exec zsh
fi

Close and open again the git bash.

Optional steps

6. Installing the Honukay theme

curl -fsSL https://raw.githubusercontent.com/oskarkrawczyk/honukai-iterm/master/honukai.zsh-theme -o ~/.oh-my-zsh/custom/themes/honukai.zsh-theme

7. Set it

sed -i 's/ZSH_THEME="robbyrussell"/ZSH_THEME="honukai"/g' ~/.zshrc

Putting this in .bashrc breaks anything trying to directly run bash commands.

if [ -t 1 ]; then
    exec zsh
fi

Didn't anyone else run into problems with VS Code because of this? I came looking for a fix but was surprised to see nobody mentioned it. For example VSCode runs npm scripts like "C:\Program Files\Git\bin\bash.exe '--login', '-i', '-c', 'npm run watch'", which doesn't work anymore.

Try to open cmd and run "C:\Program Files\Git\bin\bash.exe" --login -i -c "echo hello" and see it opens zsh but never echos anything.

Doing this instead seems to fix it:

# Check for BASH_EXECUTION_STRING to see if bash is being called with -c to execute a command.
if [[ -z "$BASH_EXECUTION_STRING" && -t 1 ]]; then
    exec zsh
fi

any idea what could cause this issue when trying to install oh-my-zsh ?

Cool. I will test that later. Thanks for that.

Change $ZSH to $ZSH_CUSTOM will be better.

Install Git Bash with ZSH, OH MY ZSH & POWERLEVEL10K | Windows Guide

Thanks to all of you guys i've create a fork of fworks works and your guys' suggestion in the comment.

guys, does anyone know how to remove this? What they write doesn't help. I tried using -f to run the function and it still appears

I've done writting the .bashrc, zsh wont showing up as git bash default theme. Can somebody help me?

I cannot believe that I'm using Zsh on Windows. It works flawlessly. I didn't encounter most of the issues that others faced here except for ERROR: this script is obsolete, please see git-completion.zsh, and using OMZ on Windows is just the icing on cake. Wish somebody would create a Scoop installer to make the installation process easier alongside Git-bash.

This is awesome! Thx everyone.. added starship prompt to mine as well. Took steps here and moved init to .zshrc:

Also running zsh in git bash as default shell within Tabby. Great for switching between git bash,
cmd, powershell, etc.

.. working!
