TypeError: Object ... has no method 'charAt' about grunt-contrib-connect

The cmd option in grunt.util.spawn should be a string as it can only run a single command at a time. Also you'll need to mark your task as async with var done = this.async(); and then call done(); within your callback signifying your task is done.

See: http://gruntjs.com/api/grunt.util#grunt.util.spawn and http://gruntjs.com/frequently-asked-questions#why-doesn-t-my-asynchronous-task-complete

Also I recommend using require('fs').readdir or readdirSync instead of spawning an ls command. It will make your gruntfile cross platform, faster and easier to maintain if you utilize as much of node as possible. http://nodejs.org/api/fs.html#fs_fs_readdir_path_callback

@tayyabhussain Object has no method 'charAt' usually occurs when something is expecting a String but gets something else in JavaScript.

For your case, looking at the grunt-phpmd docs, it looks like dir only accepts a string and not an array. Please open an issue there if you think it should otherwise. Thanks!
