fswatch

Watch a directory, run a command when something changes.

Install

Via go get:

% go get github.com/CHH/fswatch

You should now have a fswatch executable. Run fswatch -h to get all options.

Usage

The fswatch utility watches the current working directory and runs the command line given as arguments, each time a file is changed.

Some possible use cases:

  • Recompile LESS files everytime you change them.
  • Run the project's tests.

To run make test everytime a file is changed:

% fswatch make test

Known Issues

  • fswatch will trigger the command on every file change. You have to see for yourself if the command should be run or not. Therefore it's recommended to use a build tool like make or rake as target for fswatch.
  • You've to restart fswatch to make it pick up files in any created directories.
