       consolehelper - A wrapper that helps console users run system programs

       progname [ options ]

       consolehelper  is  a tool that makes it easy for console users to run system programs, doing authentication via
       PAM (which can be set up to trust all console users or to ask for a password at the system administrator's dis-
       cretion).  When possible, the authentication is done graphically; otherwise, it is done within the text console
       from which consolehelper was started.

       It is intended to be completely transparent.  This means that the user will never run the consolehelper program
       directly.  Instead, programs like /sbin/shutdown are paired with a link from /usr/bin/shutdown to /usr/bin/con-
       solehelper.  Then when non-root users (specifically,  users  without  /sbin  in  their  path,  or  /sbin  after
       /usr/bin) call the "shutdown" program, consolehelper will be invoked to authenticate the action and then invoke
       /sbin/shutdown.  (consolehelper itself has no priviledges; it calls  the  userhelper(8)  program  do  the  real

       consolehelper  requires  that  a  PAM  configuration  for every managed program exist.  So to make /sbin/foo or
       /usr/sbin/foo managed, you need to create a link from /usr/bin/foo to  /usr/bin/consolehelper  and  create  the
       file /etc/pam.d/foo, normally using the pam_console(8) PAM module.

       This program has no command line options of its own; it passes all command line options on to the program it is
