Elevated Privileges

Often you need to run a script with elevated privileges.

On Linux and OSX this means using sudo, on Windows it means using 'Run as Administrator'.

DCli abstracts Linux/OSX sudo and Windows Administrator into a single concept of 'elevated privileges'.

In DCli you can check if your script is running with elevated privileges by calling isPrivilegedUser

 if (!Shell.current.isPrivilegedUser) {
    printerr(
       'Please restart ${Script.current.exeName} using with elevated privileges');
    exit(1);
  }

Windows

Under Windows elevated privileges are pretty simple.

If any part of your script needs to run with elevated privileges then just use the 'Run as Administrator' option in windows.

You should add a call to Shell.current.isPrivilegedUser at the start of the script and force users to restart with the required privileges.

Linux/OSX

Under Linux/OSX privileged operations for more problematic.

If you need the entire script to run escalated then use the above isPrivilegedUser method however often you will want to only use escalated privileges for some of the script which is possible with the Shell.current.withPriviliged method.
