Recover file contents from "git reset --hard" (file names are another story)

recover.js

var cp = require('child_process'),
	fs = require('fs'),
	execSync = require('exec-sync');

var fsck = cp.spawn("git", ["fsck", "--cache", "--unreachable","$(git for-each-ref --format=\"%(objectname)\")"])


var stdout = '';
fsck.stdout.on('data',function(data){
	stdout += data.toString();
});

fsck.on('close',function(){
	var commits = stdout.match(/(.*)\n/g).map(function(line){
		var match = line.match(/blob\s+(.*)\n/)
		return match ? match[1] : ""
	});

	console.log(commits.length)

	commits = commits.slice(600,commits.length); // test

	commits.forEach(function(commit){

		if (commit) {
		var output = execSync('git show ' + commit);

		fs.writeFile( __dirname + "/dumps/" + commit, output, function(err){
			if (err)
				throw err
		});
		}

	});
