Load tasks in your Gruntfile.js

grunt.loadNpmTasks('grunt-h5bp-cachebuster');

If you don't using html5-boilerplate thant you should add

# .htaccess
 <IfModule mod_rewrite.c>
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.+)\.(\d+)\.(js|css|png|jpg|gif)$ $1.$3 [L]

The "h5bp_cachebuster" task

Usage

In your project's Gruntfile, add a section named h5bp_cachebuster to the data object passed into grunt.initConfig().

grunt.initConfig({
  h5bp_cachebuster: {
    options {
      algorithm: 'crc32'
    },
    css: {
      expand: true,
      cwd: 'src/css/',
      src: '**/*.css',
      dest: 'dist/css/'
    }
  }
})

It would find all css files in src/css/ dir (including subfolders) and create new files in dist/css/ dir. You can skip subfolders by changing src to *.css. It's designed to work with .htaccess snippet from html5-boilerplate so it will only change assets urls in css file (and not change assets file names in filesystem) by adding checksum before extension so it will change url('image.jpg') to url('image.12345.jpg').
