su

Simple sudo replacement utility based on OpenBSD's doas.

This library comes from the gksu application. It provides a simple API to use su and sudo in applications that need to execute tasks as an other user. It provides X authentication facilities for running applications in an X session.

gksu is a GTK+ front end for /bin/su. gksu supports login shells and preserving environment when acting as a su front end. It is useful for menu items or other graphical applications that need to ask the user's password to run as another user.
