如果你使用nodeJS。乔基达尔很有趣.围绕节点的整洁包装器.js fs.watch/fs.watchFile。

var chokidar = require('chokidar');
var watcher = chokidar.watch('file or dir', {ignored: /[/\]./, persistent: true});
watcher
  .on('add', function(path) {console.log('File', path, 'has been added');})
  .on('addDir', function(path) {console.log('Directory', path, 'has been added');})
  .on('change', function(path) {console.log('File', path, 'has been changed');})
  .on('unlink', function(path) {console.log('File', path, 'has been removed');})
  .on('unlinkDir', function(path) {console.log('Directory', path, 'has been removed');})
  .on('error', function(error) {console.error('Error happened', error);})
// 'add', 'addDir' and 'change' events also receive stat() results as second argument.
// http://nodejs.org/api/fs.html#fs_class_fs_stats
watcher.on('change', function(path, stats) {
  console.log('File', path, 'changed size to', stats.size);
});
watcher.add('new-file');
watcher.add(['new-file-2', 'new-file-3']);
// Only needed if watching is persistent.
watcher.close();
// One-liner
require('chokidar').watch('.', {ignored: /[/\]./}).on('all', function(event, path) {
  console.log(event, path);
});
