MySQL Shell command help
Hi to you all

I am fairly new to unix and a very green programmer.

Just to avoid some harsh responses as i saw in other posts: THIS ISNOT A QUESTION RELATED TO AN ASSIGNMENT OR CONTRACT" if i wanted to get something done for me, I would use my Rent A Coder or E Lance accounts. I am trying to learn how to do a few scripts in order to better understand server errors for networking.

So here is a question:

How can i determine in UNIX the amount of UNIQUE users logged in at a given time. I searched "Display unique users" and " WHO command options" and consulted man who and who info for details to no avail.

I just want to know how to display the UNIQUE number of users loged on to the shell so that my script will display either the total or unique users loged in.
I already figured out how to display the total ammount of users.

Thanks in advance

Greg

overrideshell

OverrideShell(library call)											       OverrideShell(library call)

NAME

       OverrideShell -- The OverrideShell widget class

SYNOPSIS

       #include <Xm/Xm.h>
       #include <X11/Shell.h>

DESCRIPTION

       OverrideShell is used for shell windows that completely bypass the window manager, for example, PopupMenu shells.

   Classes
       OverrideShell inherits behavior and resources from Core, Composite, and Shell.

       The class pointer is overrideShellWidgetClass.

       The class name is OverrideShell.

   New Resources
       OverrideShell defines no new resources, but overrides the XmNoverrideRedirect and XmNsaveUnder resources in the Shell class.

   Inherited Resources
       OverrideShell  inherits	behavior  and resources from the following superclasses. For a complete description of each resource, refer to the
       reference page for that superclass.

       The following table defines a set of widget resources used by the programmer to specify data. The programmer can also set the resource val-
       ues  for  the inherited classes to set attributes for this widget. To reference a resource by name or by class in a .Xdefaults file, remove
       the XmN or XmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file,  remove  the
       Xm  prefix  and	use the remaining letters (in either lowercase or uppercase, but include any underscores between words).  The codes in the
       access column indicate if the given resource can be set at creation time (C), set by using XtSetValues (S), retrieved by using  XtGetValues
       (G), or is not applicable (N/A).
