GitHub Copilot CLI brings the power of AI directly to the terminal. Never google for commands again – just ask and execute.

What is GitHub Copilot CLI?

GitHub Copilot CLI is a terminal extension that:

• Explains commands – What does this command do?
• Generates commands – How do I do X?
• Analyzes errors – Why didn't that work?

Installation

Prerequisites

• GitHub Copilot license
• Node.js 18+
• Supported shell (bash, zsh, PowerShell)

Setup

npm install -g @githubnext/github-copilot-cli
github-copilot-cli auth

The Three Main Commands

gh copilot explain

Explains complex commands:

gh copilot explain "find . -name '*.js' -exec grep -l 'TODO' {} \;"

Output: "This command finds all JavaScript files in the current directory and subdirectories that contain the word 'TODO'."

gh copilot suggest

Generates commands from natural language:

gh copilot suggest "find all files larger than 100MB"

Output: ``bash find . -type f -size +100M ``

gh? (Alias)

Quick questions:

gh? "how do I compress a folder"

Practical Applications

Git Workflows

gh copilot suggest "show commits from last week by marcel"
# Generates: git log --since="1 week ago" --author="marcel"

Docker Management

gh copilot suggest "delete all stopped containers"
# Generates: docker container prune -f

Kubernetes

gh copilot suggest "scale deployment nginx to 5 replicas"
# Generates: kubectl scale deployment nginx --replicas=5

Security

Review Before Execution

• CLI shows command before execution
• User explicitly confirms
• No automatic execution

Sensitive Data

• No passwords in prompts
• Prefer local processing
• Consider audit logs

Best Practices

Ask Precise Questions

Good: "Find Python files with more than 500 lines, sorted by size"

Bad: "Find large files"

Provide Context

Good: "In an npm project: how do I update all dependencies?"

Bad: "Update packages"

Workflow Integration

Shell Aliases

alias ghs='gh copilot suggest'
alias ghe='gh copilot explain'

CI/CD

• Command generation in pipelines
• Automate documentation
• Accelerate onboarding

Conclusion

GitHub Copilot CLI makes the terminal more accessible and productive. A must-have for every developer.
