Quick Start 🚀

Prerequisites

• Python 3.7 or higher
• Anthropic API key

Installation

Option 1: Install with uv (Recommended - Fast!)

uv is a blazingly fast Python package installer and resolver written in Rust. It's 10-100x faster than pip!

1. Navigate to the sysadmin directory:

   cd sysadmin/
   

2. Run the uv installer:

   ./install-uv.sh
   

   This will:

   • Install uv automatically if not present (macOS/Linux)
   • Check for Python 3
   • Install Python dependencies much faster than pip
   • Detect your operating system for optimal command generation
   • Set up the ai alias for easy access
   • Create symlinks and configure your shell

   Why uv?

   • ⚡ 10-100x faster than pip for dependency resolution and installation
   • 🦀 Written in Rust for maximum performance
   • 🔒 Drop-in replacement for pip with the same interface
   • 📦 Better dependency resolution

   📖 For detailed uv installation instructions and troubleshooting, see UV_INSTALL.md

Option 2: Install with pip (Traditional)

1. Navigate to the sysadmin directory:

   cd sysadmin/
   

2. Run the automated installer:

   ./install.sh
   

   This will:

   • Check for Python 3 and pip (with helpful installation guidance if missing)
   • Install Python dependencies with error handling and troubleshooting tips
   • Detect your operating system for optimal command generation
   • Set up the ai alias for easy access
   • Create symlinks and configure your shell
   • Handle permission issues gracefully (script won't fail on chmod/symlink errors)

   Multi-User Friendly: The installer can be run by multiple users from the same directory. Each user gets their own alias and symlink configuration without affecting others.

   Note: If pip is missing, the installer will provide specific commands for your operating system to install it.

3. Set up your API key:

   export ANTHROPIC_API_KEY="your_api_key_here"
   

   Or create a .env.secrets file:

   ANTHROPIC_API_KEY=your_api_key_here
   

4. Test the installation:

   ai --help
   ai "show disk usage"
   

Option 3: Install as a Python package with uv

If you prefer to install sysadmin-ai as a Python package:

# Install uv if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install sysadmin-ai
uv pip install .

# Or install in a virtual environment
uv venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv pip install .

After installation, you can use the ai or sysadmin-ai commands directly from anywhere.

Usage Examples 📝

Easy Access with ai Alias

After installation, you can use the short ai command:

# Interactive mode
ai --interactive

# Single commands
ai "show disk usage"
ai "check system memory"
ai "find large files in /tmp"
ai "list running services"
ai "show network connections"

Interactive Mode

ai --interactive

Then type natural language commands:

sysadmin_ai> show me disk usage
sysadmin_ai> find large files in /var/log
sysadmin_ai> backup my home directory
sysadmin_ai> check which processes are using the most CPU
sysadmin_ai> update system packages
sysadmin_ai> restart apache service
sysadmin_ai> create a new user named john
sysadmin_ai> add user to sudo group
sysadmin_ai> check system memory usage

Single Command Mode

# Commands
ai "show disk usage"
ai "find files larger than 100MB in /tmp" 
ai "check system memory usage"
ai "list all running services"
ai "show network connections"

# Questions
ai "what is uvx and where does it install files?"
ai "how do I configure SSH key authentication?"
ai "what's the difference between systemctl and service?"
ai "where are nginx configuration files located?"
ai "explain how Linux file permissions work"

OS-Specific Command Generation

The tool automatically detects your operating system and generates appropriate commands:

# Check detected OS
ai --show-os

# Override OS detection (useful for remote administration)
ai --target-os linux-ubuntu "check system memory"
ai --target-os macos "list running services"
ai --target-os linux-centos "update packages"

Supported Systems:

• macOS: Uses vm_stat, launchctl, brew
• Ubuntu/Debian: Uses free, systemctl, apt
• CentOS/RHEL: Uses free, systemctl, yum
• Arch Linux: Uses free, systemctl, pacman
• FreeBSD: Uses top, service, pkg
• Generic Unix/Linux: Fallback commands

Direct Execution

./sysadmin_ai.py --help
./sysadmin_ai.py --interactive
./sysadmin_ai.py "show disk usage"

With Safety Options

ai --safe-mode "clean up temporary files"
ai --auto-confirm "show running services"

Question & Answer Mode 🤔

The tool now intelligently detects when you're asking a question and provides detailed explanations with web search integration.

Intelligent Intent Detection

Claude automatically determines whether you're asking a question or requesting commands - no special syntax needed! Just talk naturally and Claude will:

• Provide explanations for questions about concepts, tools, and configurations
• Generate commands for actionable requests like "show disk usage"

Web Search Integration

Claude can search the web for current information when answering questions:

ai "what is the latest version of Docker?"
ai "how to install Node.js on Ubuntu 22.04?"
ai "what are the best practices for SSH security?"

Configuration Options

# Configure settings (including web search)
ai --config

# Disable web search for answers
ai --disable-web-search "what is systemd?"

Natural Language Examples

Claude automatically determines your intent - no special syntax needed:

Questions (Claude provides detailed explanations):

• "what is uvx and where does it install files?"
• "how do I configure SSH key authentication?"
• "what's the difference between apt and snap?"
• "where are log files typically stored?"
• "explain how cron jobs work"

Commands (Claude generates executable bash):

• "install docker" → brew install docker (macOS)
• "check disk usage" → df -h
• "find large files" → find . -type f -size +100M
• "restart nginx service" → sudo systemctl restart nginx
• "show running processes" → ps aux

API Key Management 🔐

The tool supports multiple ways to provide your Anthropic API key:

1. Environment Variable (Recommended)

export ANTHROPIC_API_KEY="your_api_key_here"
./sysadmin-ai.py --interactive

2. Local .env.secrets File

Create a .env.secrets file in the sysadmin directory:

ANTHROPIC_API_KEY=your_api_key_here

3. Embedded Key (For Deployment)

For deploying to remote servers where environment setup is complex:

./sysadmin_ai.py --embed-key sysadmin-ai-embedded.py

This creates a version with an encrypted, embedded API key. You'll need to enter a passphrase when running it.

4. Interactive Prompt

If no key is found, the tool will prompt you to enter it securely.

Deployment Options 📦

Troubleshooting 🔍

Common Issues

Slow pip installation? Try using uv instead! It's 10-100x faster:

# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Then use the uv installer
./install-uv.sh

pip3 not found during installation The installer will provide specific commands for your OS. Common solutions:

# macOS
brew install python

# Ubuntu/Debian
sudo apt update && sudo apt install python3-pip

# CentOS/RHEL
sudo yum install python3-pip

# Fedora
sudo dnf install python3-pip

# Arch Linux
sudo pacman -S python-pip

uv not found after installation If uv was just installed, you may need to restart your shell or source the environment:

source $HOME/.cargo/env
# Or restart your terminal

ImportError: No module named 'requests'

pip install requests cryptography
# or if pip3 is available
pip3 install requests cryptography

Permission errors during pip install Try installing with user flag or system-wide:

pip3 install -r requirements.txt --user
# or system-wide (requires sudo)
sudo pip3 install -r requirements.txt

API Key Not Found

• Check environment variable: echo $ANTHROPIC_API_KEY
