Step-by-Step .BAT File Code Explained

Let’s break down what each line does:

  • @echo off: Hides command display for cleaner output.
  • cd %USERPROFILE%: Navigate to your home directory.
  • git clone https://github.com/google/gemini-cli.git: Clones the Gemini CLI source code.
  • cd gemini-cli: Enters the project directory.
  • If package.json npm exists, install it. It installs dependencies if applicable.
  • set PATH=%CD%;%PATH%: Adds Gemini CLI to your terminal PATH temporarily.
  • gemini –version: Checks if the installation was successful.
  • pause: Keeps the terminal open so you can review the output.

Note: Manual changes to system environment variables are needed for permanent PATH addition.
