fswatch

fswatch is a simple command-line tool for watching filesystem changes and running a command in response to them.

Installing

Currently the only way to install fswatch is the golang toolkit:

$ go install github.com/tasdomas/fswatch

Usage

fswatch [ --events create,write,remove,rename,chmod ] [ --command <command> ]

By default fswatch will listen for all events on a specified path (a directory or a file). The events include:

• create: creating a file or subdirectory
• write: writing to a file
• remove: removing of a file or subdirectory
• rename: renaming a file or subdirectory
• chmod: changing access permissions

Watching a directory will watch for changes to files and subdirectories directly inside it but will not watch for changes inside subdirectories.

The change event's path and comma-separated list of event names can be passed to the command using {Path} and {Events} placeholders:

fswatch --command 'echo {Path} {Events}' ./
