NAME
       suexec - Switch user before executing external programs

SYNOPSIS
       suexec -V

SUMMARY
       suexec  is used by the Apache HTTP Server to switch to another user before executing CGI programs. In order to achieve this, it must run as
       root. Since the HTTP daemon normally doesn't run as root, the suexec executable needs the setuid bit set and must  be  owned  by  root.	It
       should never be writable for any other person than root.

       For   further   information   about   the   concepts   and  the	security  model  of  suexec  please  refer  to	the  suexec  documentation
       (http://httpd.apache.org/docs/2.4/suexec.html).

OPTIONS
       -V     If you are root, this option displays the compile options of suexec. For security reasons all configuration options  are	changeable
	      only at compile time.
