you can use node's process.argv command line arguments.

the code below can called with: grunt watch --dir myfolder

grunt.registertask('watch', function() {     var args = process.argv;     var folder = args[args.indexof('--dir') + 1];     console.log('watch folder: ', folder); // "watch folder: myfolder" });
