AI Terminal Assistants: Command Line Gets Intelligent

This article is written in English. Our training modules are available in French.

The command line has been the power user's domain for decades—efficient but demanding expertise. Now, AI-powered terminal assistants are democratizing this power, helping developers and system administrators accomplish complex tasks through natural language while learning command patterns along the way. From GitHub Copilot CLI to Claude Code, a new generation of tools is making the terminal accessible and powerful.

This comprehensive guide explores the AI terminal assistant landscape, comparing tools, demonstrating capabilities, and offering practical guidance.

Open Source Options

Core Capabilities

Natural Language to Commands

Example Interaction:

User: "Find all Python files modified in the last week 
       and count lines of code"

AI: I'll create a command for that:

    find . -name "*.py" -mtime -7 -exec wc -l {} + | 
    tail -n 1

    This will:
    - Search for .py files
    - Only those modified in last 7 days
    - Count lines in each
    - Show total at the end

    Run this command? [y/n]

Command Explanation

User: explain "tar -xzvf archive.tar.gz"

AI: This command extracts a compressed archive:

    tar     - Tape archive utility
    -x      - Extract files
    -z      - Decompress using gzip
    -v      - Verbose (show files being extracted)
    -f      - Specify file name (archive.tar.gz)

    In plain English: "Unzip and unpack archive.tar.gz,
    showing me each file as it's extracted."

Error Recovery

$ docker biuld .
docker: 'biuld' is not a docker command.

User: help

AI: I see a typo. You meant:

    docker build .

    This builds a Docker image from the Dockerfile
    in the current directory.
    
    Run corrected command? [y/n]

Multi-Step Workflows

User: "Set up a new Python project with virtual env,
       install requests library, and create basic structure"

AI: I'll execute these steps:

    1. Create project directory
       mkdir my-project && cd my-project

    2. Create virtual environment
       python -m venv venv

    3. Activate and install
       source venv/bin/activate
       pip install requests

    4. Create structure
       mkdir src tests
       touch src/__init__.py tests/__init__.py
       touch src/main.py requirements.txt

    Proceed with all steps? [y/n/step-by-step]

Deep Dive: Claude Code

Features

Agentic Execution:

• →Runs multiple commands autonomously
• →Makes decisions based on output
• →Handles errors and retries
• →Asks questions when needed

Codebase Understanding:

• →Indexes your project
• →Understands context
• →Makes informed suggestions
• →Cross-file awareness

Safety Features:

• →Confirms dangerous operations
• →Explains before executing
• →Can operate in read-only mode
• →Respects .gitignore

Usage Example

$ claude-code "refactor the auth module to use JWT 
               instead of sessions"

Claude: I'll analyze the auth module and plan the refactor.

📁 Found auth module at src/auth/
📄 Files to modify:
   - src/auth/middleware.py
   - src/auth/handlers.py  
   - src/auth/models.py
   - requirements.txt

📋 Plan:
1. Add PyJWT to requirements.txt
2. Create JWT token generation in handlers.py
3. Update middleware to validate JWT
4. Remove session dependencies
5. Update tests

Shall I proceed? [y/n/show details]

Deep Dive: GitHub Copilot CLI

Installation

# Install GitHub CLI
brew install gh

# Authenticate
gh auth login

# Install Copilot extension
gh extension install github/gh-copilot

Usage Patterns

Command Generation:

$ gh copilot suggest "find large files over 100MB"

# Suggestion:
find . -type f -size +100M

? Select an option
> Execute command
  Explain command
  Revise query
  Exit

Explain Commands:

$ gh copilot explain "awk '{sum+=$1} END {print sum}' file.txt"

This awk command:
1. For each line, adds the first field ($1) to a running sum
2. After processing all lines (END), prints the total
3. Effectively sums up the first column of numbers in file.txt

Git Workflow:

$ gh copilot suggest "squash last 3 commits"

# Suggestion:
git reset --soft HEAD~3 && git commit

? Would you like to execute this?

Safety Considerations

Risks of AI in Terminal

Safety Features to Look For

Command Preview:

• →Always show command before execution
• →Explain what it will do
• →Highlight irreversible actions

Confirmation Prompts:

⚠️  This command will delete files:
    rm -rf ./build/*
    
    Are you sure? Type 'yes' to confirm:

Sandboxing:

• →Dry-run modes
• →Restricted execution environments
• →Rollback capabilities

Best Practices

Terminal AI Safety Rules:

1. REVIEW every command before execution
2. UNDERSTAND before you confirm
3. BACKUP before destructive operations
4. TEST in safe environment first
5. DON'T paste secrets into prompts
6. USE with caution on production systems
