Based on mxcl's work here: https://gist.github.com/149491/ This is a ruby script that uses Mac OS X's FSevents API and rsync to sync changes from the local file system to a remote location. It can be invoked like this from within the directory you want to sync: ruby syncer2.0 -e excluded_file -f -r -s -p 2222 -u username -H myhost.com -d "/the/remote/directory/" growlnotify and ruby gems must be installed on your system. To install ruby gems: curl -O http://files.rubyforge.vm.bytemark.co.uk/rubygems/rubygems-1.3.5.tgz tar xzvf rubygems-1.3.5.tgz cd rubygems-1.3.5 sudo /usr/bin/ruby setup.rb sudo gem install rb-fsevent
