Gemini's Command Line Tool: A Free Productivity Revolution

Integrating the power of AI into the Linux command line is no longer a distant dream, thanks in part to Gemini's command line interface (CLI). For those who frequently leverage the Linux terminal, the infusion of AI is not just transformative but here to stay. While incorporating AI into your Linux environment isn’t compulsory, it offers significant advantages for users who routinely engage with the command line.

The Potential of Gemini CLI

Gemini CLI is designed to be installed locally and can perform a variety of tasks including generating content, solving problems, conducting deep research, and managing tasks. Although it was originally tailored for developers, it's equally accessible for users desiring AI functionalities without the need to use a web browser or a third-party graphical interface.

The initial setup of Gemini CLI may seem daunting, but I will guide you through the process.

Why is Gemini CLI a Game Changer?

Gemini stands out as the pioneering command-line AI tool capable of handling diverse forms of data including text, images, audio, and video. It merges the power of AI with the command line, while simultaneously enabling direct access to Linux commands.

Due to its extensive capabilities, caution is advised while handling sensitive information. I will demonstrate access within a designated directory to ensure data protection.

The inclusion of built-in utilities for tasks like Google Search, file operations, and web integration, alongside support for custom setups, further amplifies its versatility.

The free version allows up to 60 requests per minute and 1,000 per day using your Google account.

Steps to Install Gemini CLI on Ubuntu

The prerequisites are a running Ubuntu Linux (or an Ubuntu-based system), sudo user access, and an active Google account. Ensure you’re signed into Google via your primary web browser before initiating Gemini CLI.

1. Open Terminal

Start by launching your preferred terminal application.

2. Node.js Installation

Node.js needs to be installed because Gemini CLI utilizes the Node.js package manager (npm). Use the following command to initiate installation.

3. Installing npm

Proceed by installing npm. Execute the command:

4. Gemini CLI Setup

Various instructions exist for installing Gemini CLI via npm, many resulting in a 'command not found' error. The most reliable method is executing the command:

Once the installation is complete, Gemini is ready for use.

If you encounter execution errors, update to the latest version using the following commands and reinstall npm:

First Steps with Gemini

1. Launch Gemini

Begin by executing Gemini with this simple command:

2. Choose a Theme

You'll be prompted to select a theme within the curses-based interface. Navigate using arrow keys and confirm with Enter.

3. Decide on Authentication

Logging in via your Google account is the easiest authentication method, although Gemini API Key or Vertex AI can also be used. Confirm 'Login with Google' and proceed.

4. Get Authenticated

Upon pressing Enter, your default browser will open, allowing you to select a Google account. Post-authentication, return to the terminal which transitions to a Gemini prompt ready for your queries.

Operating Gemini CLI

After installation, put Gemini CLI to work in a structured way.

Create a new directory for organized project handling:

mkdir ~/GEMINI

Switch to the newly created directory with:

cd ~/GEMINI

Command to run Gemini:

gemini

You can specify a preferred language model for specific queries, for example, the qwen3-coder model for programming queries. Use the command:

gemini -m qwen3-coder

Pose your question, as shown:

How do I create a Python module?

Gemini may add some humor during processing, such as quips like 'Rickrolling my boss.'

Depending on the query, Gemini might need to execute specific commands or suggest changes. For example, it provided a step-by-step guide for Python module creation.

Post-query, the resulting sample module is available in the ~/GEMINI directory, alongside a summary of steps taken.

Exiting Gemini is easy: simply hit Ctrl+C twice.

There you have it—installing and using Gemini CLI on Linux. Experience the synergy of AI right within your terminal.
