Tool Spotlight: Gemini CLI - AI in Your Terminal

This week, I got a chance to try out something pretty interesting - Gemini CLI, which is an experimental tool that brings AI right into your Linux terminal.

Think of it like having ChatGPT inside your shell. You can type in a question or command, and Gemini responds directly in the terminal - no browser needed.

Here’s what it can do so far:

  • ✅ Explain complex Linux commands
  • ✅ Generate quick shell or Python code snippets
  • ✅ Help troubleshoot errors
  • ✅ Turn natural language into usable terminal commands

It’s still early and a bit rough around the edges, but honestly, it feels like a peek into the future of how we’ll work with the command line.

If you’re curious, I put together a quickstart guide so you can try it out yourself.
