Answer by koppor for How to add more commands to Git Bash?

With recent Git for Windows installations, installing additional shell scripts and programs is pretty easy.

Simply put the executables into C:\Program Files\Git\usr\bin (%ProgramFiles%\Git\usr\bin).

I recommend installing git using chocolateychoco install git --params "/GitAndUnixToolsOnPath /WindowsTerminal", because you can update git (and all other tools installed with chocolatey) by executing choco upgrade all.

Example for git-fresh

Copy the file git-fresh to C:\Program Files\Git\usr\bin.

Example for adr-tools

1. Download a zip package from the releases page
2. Unzip the package
3. Copy everything from src/ into C:\Program Files\Git\usr\bin
