 Your command should not depend on any current working directory or environment variables in order to execute correctly, and you should take care to use absolute paths and not relative paths.
 
 ## Behavior
-On OS X, `sudo-prompt` should behave just like the `sudo` command in the shell. If your command does not work with the `sudo` command in the shell (perhaps because it uses `>` redirection to a restricted file), then it may not work with `sudo-prompt`. However, it is still possible to use sudo-prompt to get a privileged shell, [see this closed issue for more information](https://github.com/jorangreef/sudo-prompt/issues/1).

 On Linux, `sudo-prompt` will use either `pkexec` or `kdesudo` to show the password prompt and run your command. Where possible, `sudo-prompt` will try and get these to mimic `sudo`. Depending on which binary is used, and due to the limitations of some binaries, the name of your program or the command itself may be displayed to your user. `sudo-prompt` will not use `gksudo` since `gksudo` does not support concurrent prompts. Passing `options.icns` is currently not supported by `sudo-prompt` on Linux. Patches are welcome to add support for icons based on `polkit`.

 You should never rely on `sudo-prompt` to execute your calls in order. If you need to enforce ordering of calls, then you should explicitly order your calls in your application. Where your commands are short-lived, you should queue your calls to `exec()` to make sure your user is not overloaded with password prompts.
