execute a command as another user

-s [command]
            The -s (shell) option runs the shell specified by the SHELL environment variable if it is set
            or the shell as specified in the password database.  If a command is specified, it is passed
            to the shell for execution via the shell's -c option.  If no command is specified, an
            interactive shell is executed.

-A          Normally, if sudo requires a password, it will read it from the user's terminal.  If the -A
            (askpass) option is specified, a (possibly graphical) helper program is executed to read the
            user's password and output the password to the standard output.  If the SUDO_ASKPASS
            environment variable is set, it specifies the path to the helper program.  Otherwise, if
            /etc/sudo.conf contains a line specifying the askpass program, that value will be used.  For
            example:

                # Path to askpass helper program
                Path askpass /usr/X11R6/bin/ssh-askpass

            If no askpass program is available, sudo will exit with an error.
