Directory Sync Utility

This directory contains a tool for syncing a local directory to a remote host in real time. It watches for file changes and transfers them immediately via SCP, making it useful for live development on a remote server.

Scripts

Script	Description
`dir-sync.sh`	Improved version — recommended
`scpsync.sh`	Original version

Quick Start

./dir-sync.sh -s /path/to/local/dir/ -d /path/to/remote/dir/ -r sshhost

The script starts watching the local directory immediately. Press Ctrl+C to stop — it will reset the remote repository (git reset --hard) and clear the remote cache before exiting.

Options

Option	Description
`-s, --source <path>`	Local directory absolute path
`-d, --dest <path>`	Remote directory absolute path
`-r, --remote-host <h>`	Remote SSH host (as configured in `~/.ssh/config`)
`-h, --help`	Print help

If an option is omitted, the script falls back to the default values defined at the top of the script.

How It Works

File watching: fswatch monitors the source directory for any change, excluding .git/
Batch end marker: fswatch --batch-marker emits a NoOp signal at the end of each batch
File sync: each changed file is transferred with scp, preserving the relative path under the destination directory
Cache clear: on each NoOp (end of batch), composer front-cache-clear is run on the remote
Cleanup on exit: Ctrl+C triggers git reset --hard and a final cache clear on the remote

Default Configuration

Edit the three constants at the top of dir-sync.sh to set your own defaults:

DEFAULT_LOCAL_PATH='/path/to/local/dir/'
DEFAULT_REMOTE_PATH='/path/to/remote/dir/'
DEFAULT_HOST='devac'

Requirements

fswatch — file system watcher
scp and ssh — standard OpenSSH tools
A remote host configured in ~/.ssh/config (password-less key auth recommended)
composer available on the remote host (for cache clearing)

Installing fswatch

# macOS
brew install fswatch

# Linux (Ubuntu/Debian)
sudo apt install fswatch
