Exit Codes

Code	Description
0	Success
1	Error (file not found, invalid platform, parsing error, etc.)

Error Handling

The CLI provides clear error messages for common issues:

File Not Found:

Error: Running config file not found: /path/to/missing.conf

Invalid Platform:

Error: Unknown platform: invalid_platform. Use 'list-platforms' to see available platforms.

Permission Denied:

Error: Permission denied reading running config: /path/to/file.conf

Tips

1. Use Tab Completion: If your shell supports it, enable tab completion for easier command entry
2. Combine with Shell Tools: Pipe output to less, grep, or other tools for analysis
3. Check File Paths: Always use absolute paths or ensure you're in the correct directory
4. Review Before Applying: Always review generated commands before applying them to production devices
