commands are now run in a subshell, this is often needed for chains of commands where it is not the main command to need the privilege but a subcommand does, for example us echo 30 > /sys/class/backlight/*/brightness it is not echo that needs the elevated privilege but the redirection '>' does.
US - User {Switcher,Shell}
Opens a shell as a different user without needing to authenticate as that user.
This is similar to the behavior of su but it allows to execute privileged
and/or commands as any other user without needing their password.
