claw2claw-filetransfer

File transfer so smooth, even a lobster can do it. 🦞

Send files between OpenClaw agents without the drama. rsync over SSH - delta transfers, compression, progress bars. Linux, macOS, Windows - we got you covered.

When to Trigger This Skill

Use this skill when user wants to:

• Transfer files between two OpenClaw agents
• Sync project directories bidirectionally
• Backup files to a remote agent
• Pull logs/data from remote agent
• Set up SSH connection between agents
• Move bits from A to B without crying

Quick Start

# 1. Set up remote agent (one-time)
claw2claw setup 192.168.1.100 --user root

# 2. Send files like a pro
claw2claw send /backup.tar.gz

# 3. Get files back
claw2claw get /remote/logs.txt

# 4. Sync entire directories
claw2claw sync-to-remote ./my-project/

Installation

Linux

# Pre-installed on most distros
sudo apt install rsync

macOS

brew install rsync

Windows

# Option A: Git Bash (recommended)
# Download from https://git-scm.com

# Option B: cwrsync
# Download from https://www.itefix.net/cwrsync

# Option C: WSL
wsl --install

Platform-Specific Notes

Git Bash / MSYS2

• Uses Unix-style paths: /c/Users/...
• rsync usually pre-installed
• Works out of the box

Windows Command Prompt / PowerShell

• Use full paths or forward slashes: C:/Users/...
• Or use cwrsync

WSL

• Detected as Linux, works perfectly
• Can communicate with Windows filesystem

Cygwin

• Install via Cygwin setup
• Path: /cygdrive/c/Users/...

Performance Tips

Compression

# On (default) - for text files
claw2claw send /logs/*.log

# Off - for already compressed files
claw2claw send /backup.tar.gz --no-compress

Bandwidth

# Limit to 500 KB/s
RSYNC_BWLIMIT=500 claw2claw send /huge-file.tar.gz

Large Files

# rsync auto-resumes interrupted transfers
# Just run same command again
claw2claw send /huge-file.tar.gz

Selective Sync

# Only sync specific patterns
# Use --include and --exclude in rsync manually
# Or sync specific subdirectories
claw2claw sync-to-remote ./src/

Testing Connection

Quick Test

claw2claw status

Manual SSH Test

ssh -o ConnectTimeout=5 user@host "echo OK"

Test File Transfer

# Small test file first
echo "test" > /tmp/test.txt
claw2claw send /tmp/test.txt /tmp/
claw2claw get /tmp/test.txt /tmp/
rm /tmp/test.txt

Troubleshooting

"rsync: command not found"

# Linux
sudo apt install rsync

# macOS  
brew install rsync

# Windows
# Install Git Bash or cwrsync

"Permission denied"

# Re-run setup to add SSH key
claw2claw setup <host> --user <user>

"Connection timed out"

# Check host reachable
ping <host>

# Check port open
nc -zv <host> 22

Examples

Daily Backup

claw2claw send /backups/daily-$(date +%Y%m%d).tar.gz /backups/

Project Sync

# Morning
claw2claw sync-from-remote /workspace/project/

# Evening  
claw2claw sync-to-remote /workspace/project/

Log Collection

claw2claw get /var/log/syslog ./logs/
