How to `cd` to some directory

I need to change the directory before executing script. I've found a solution, but I'm not sure that it is the best way to do it.

```
{
    "scripts": [
        {
            "command": "/bin/sh",
            "args": [
                "-c",
                "cd /Users/bessarabov/Desktop; pwd"
            ]
        }
    ]
}
```

Maybe you can recommend something?
