How to Install Gemini CLI

Getting started with Gemini CLI is quick and straightforward, provided you meet the basic requirements.

Prerequisites

Installation Steps

For Linux and macOS:

Open your terminal and run:

npm install -g @google/gemini-cli

Alternatively, for a one-time test without installation:

npx https://github.com/google-gemini/gemini-cli

For Windows:

Use PowerShell or Windows Terminal with administrator privileges and execute the same npm or npx command.

Once installed, launch the CLI by typing:

gemini

You’ll be greeted with an interactive prompt ready to accept natural language queries and commands.

Authentication and API Configuration

Gemini CLI supports two authentication methods:

  1. Personal Google Account (Default)

    • Free tier access
    • Rate limits: 60 requests per minute, 1,000 per day

  2. Google AI Studio API Key (Recommended for Heavy Usage)

    • Higher rate limits
    • Access to advanced models like Gemini Pro

To use an API key:

  1. Visit Google AI Studio and generate your key.

  2. Set it as an environment variable:

    export GOOGLE_GENAI_API_KEY="your-api-key-here"
  3. For persistent configuration, add this line to your .bashrc, .zshrc, or shell profile.

This ensures secure, seamless access across sessions.

Essential Commands to Supercharge Your Workflow

Gemini CLI uses a slash-command syntax (/command) to unlock advanced features. Here are some must-know commands:

These commands make it easy to manage long-running projects and maintain continuity across development cycles.

Leverage File and Directory Analysis

One of Gemini CLI’s standout features is its ability to analyze real project files. Use the @ symbol to reference files or directories:

@src/components analyze the architecture of my React components
@. explain how this application works

This deep integration allows the AI to understand your project structure, dependencies, and logic—enabling intelligent refactoring suggestions, documentation generation, and migration planning.

Automate Tasks with Shell Integration

Need to run system commands? Gemini CLI lets you execute shell operations directly using !.

Examples:

!git status
!npm outdated

Use !. to enter full shell mode for multi-step automation tasks.

This feature is especially useful for scripting repetitive DevOps routines or validating AI-generated solutions in real time.

Practical Use Cases for Developers

1. Codebase Migration Planning

Migrating from one framework to another? Let Gemini analyze your existing code:

@src/app analyze this Angular code and propose a migration to React with the same functionalities

The AI will generate a step-by-step plan, including component mapping and dependency updates.

2. App Generation from Mockups

Upload a PDF mockup and generate a working prototype:

@mockup.pdf generate me a React app that implements these screens

Leveraging multimodal input, Gemini interprets visual designs and translates them into functional code.

3. Intelligent Debugging

Debug faster by analyzing logs:

@error.log explain this error and suggest solutions

Gemini identifies root causes and offers actionable fixes—reducing time spent on trial-and-error troubleshooting.

4. Automated Documentation

Generate comprehensive API docs:

@src generate complete documentation for this API with usage examples

Perfect for onboarding new team members or maintaining up-to-date references.

5. DevOps Script Creation

Create automation scripts on demand:

Create a bash script that:

  • Backs up my database
  • Compresses logs older than 7 days
  • Sends a report via email

Gemini generates clean, executable scripts tailored to your needs.

Q: Does it support image inputs?
A: Yes. Gemini CLI supports multimodal inputs, allowing you to upload screenshots or design mockups for analysis.

Q: How secure is my data when using Gemini CLI?
A: Data processed through the CLI is subject to Google’s privacy policies. Avoid uploading sensitive or proprietary information unless using enterprise-grade configurations.

Q: Can I use Gemini CLI offline?
A: No. The tool requires internet connectivity to communicate with Google’s AI servers.

Q: Which programming languages does it support?
A: All major languages—including JavaScript, Python, Go, Rust, and Java—are fully supported due to Gemini’s broad training data.
