Quick Start

Installation

```bash

Clone the repository

git clone cd comfy-fs

Build the project

cargo build --release

Add to PATH (optional)

cp target/release/comfy-fs /usr/local/bin/ ```

First-Time Setup

When you run comfy-fs for the first time, it will guide you through the configuration:

```bash $ comfy-fs list /

🚀 Welcome to Comfy File Server CLI! ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

This tool helps you access the company file server easily. For detailed setup instructions, visit:

📖 https://www.notion.so/comfy-org/File-Server-Guide-2436d73d3650803f8aedcb7d2177d347

Let's configure your connection settings:

Server IP address: 192.168.1.100 Username: myusername Password: **** Preferred protocol (1=SMB, 2=FTP) [default: 1]: 1

✅ Configuration complete! ```

To reconfigure later, run:

bash comfy-fs config

Usage

Basic Commands

List files on the server:

bash comfy-fs list / comfy-fs list /documents --sort name --reverse

Browse files interactively:

bash comfy-fs browse comfy-fs browse /documents

Download files:

```bash

Single file

comfy-fs download /path/to/file.pdf ./downloads/

Multiple files with wildcards

comfy-fs download "/documents/.pdf" ./downloads/ comfy-fs download "/reports/2024" ./reports/ ```

Upload files:

```bash

Single file

comfy-fs upload document.pdf --dest /documents/

Multiple files

comfy-fs upload *.jpg report.pdf --dest /uploads/ ```

Synchronize directories:

```bash

Two-way sync between local and remote

comfy-fs sync ./local-folder /remote-folder ```

Interactive mode:

```bash comfy-fs interactive

or just

comfy-fs ```

Advanced Usage

Configure different servers:

bash comfy-fs config --server 192.168.1.200 --username user2

Sort file listings:

bash comfy-fs list / --sort modified # by date (default) comfy-fs list / --sort name # alphabetically comfy-fs list / --sort size # by file size comfy-fs list / --sort type # by file type comfy-fs list / --reverse # reverse sort order

Wildcard patterns:

• * - matches everything
• *.ext - files with specific extension
• prefix* - files starting with prefix
• *suffix - files ending with suffix

Interactive TUI

The interactive mode provides a full-screen file browser with:

• Arrow keys: Navigate files and directories
• Enter: Enter directories or download files
• Backspace: Go up one directory
• Space: Toggle file selection
• Tab: Change sort mode (modified → name → size → type)
• d: Download selected files
• q: Quit

• Integration Tests: 20 tests covering CLI functionality
• Mock Tests: Using mockall for isolated testing
• Total Coverage: 45+ tests ensuring reliability

```bash

Run all tests

cargo test

Run specific test suite

cargo test --test integrationtest cargo test --test uploaddownload_test

Run with verbose output

cargo test -- --nocapture ```

Configuration

Configuration is stored in your system's config directory:

• Linux: ~/.config/comfy-fs/config.json
• macOS: ~/Library/Application Support/com.comfy.comfy-fs/config.json
• Windows: %APPDATA%\comfy\comfy-fs\config.json

Configuration File Format

json { "server_ip": "192.168.1.100", "username": "myusername", "default_protocol": "Ftp" }

Note: Passwords are not stored in the config file for security reasons.

Performance

• Parallel Downloads: Up to 4 concurrent connections by default
• Memory Efficient: Streaming file transfers
• Fast TUI: 60fps responsive interface
• Minimal Overhead: Rust's zero-cost abstractions

Benchmarks

On a 2.5GbE connection:

• Single file download: ~250MB/s
• Parallel downloads: ~240MB/s aggregate
• File listing: <100ms for 1000 files

Troubleshooting

Connection Issues

```bash

Test basic connectivity

comfy-fs list /

Check configuration

comfy-fs config

Verify server credentials in docs/

```

Performance Issues

```bash

Check available bandwidth

Ethernet: up to 250MB/s (2.5GbE)

WiFi: varies by network

For better performance, use ethernet with 2.5GbE dongles

```

Common Errors

"Failed to connect": Check network connection and server IP "Authentication failed": Verify username and password "Permission denied": Check file/directory permissions on server "File not found": Verify the remote path exists
