Use what you have putting '2 > /dev/null' on the end.

This puts the STD ERR (errors) into /dev/null....the big 'black hole' of unix.

There is the option to put STD OUT to /dev/null as well....but you want to see the output - so not good for this example.

If you weren't intereseted in getting any output from a command (either errors or output - then you could use 2>&1 >/dev/null.

This pipes std error to std out - then puts it all to dev null.

find

find(n) 							    [incr Tcl]								   find(n)

__________________________________________________________________________________________________________________________________________________

NAME

       find - search for classes and objects

SYNOPSIS

       itcl::find option ?arg arg ...?
_________________________________________________________________

DESCRIPTION

       The find command is used to find classes and objects that are available in the current interpreter.  Classes and objects are reported first
       in the active namespace, then in all other namespaces in the interpreter.

       The option argument determines what action is carried out by the command.  The legal options (which may be abbreviated) are:

       find classes ?pattern?
	      Returns a list of [incr Tcl] classes.  Classes in the current namespace are listed first, followed by classes in	all  other  names-
	      paces in the interpreter.  If the optional pattern is specified, then the reported names are compared using the rules of the "string
	      match" command, and only matching names are reported.

	      If a class resides in the current namespace context, this command reports its simple name--without any qualifiers.  However, if  the
	      pattern  contains  :: qualifiers, or if the class resides in another context, this command reports its fully-qualified name.  There-
	      fore, you can use the following command to obtain a list where all names are fully-qualified:
	      itcl::find classes ::*

       find objects ?pattern? ?-class className? ?-isa className?
	      Returns a list of [incr Tcl] objects.  Objects in the current namespace are listed first, followed by objects in	all  other  names-
	      paces in the interpreter.  If the optional pattern is specified, then the reported names are compared using the rules of the "string
	      match" command, and only matching names are reported.  If the optional "-class" parameter is specified, this list is  restricted	to
	      objects  whose  most-specific class is className.  If the optional "-isa" parameter is specified, this list is further restricted to
	      objects having the given className anywhere in their heritage.

	      If an object resides in the current namespace context, this command reports its simple name--without any	qualifiers.   However,	if
	      the  pattern  contains  ::  qualifiers,  or if the object resides in another context, this command reports its fully-qualified name.
	      Therefore, you can use the following command to obtain a list where all names are fully-qualified:
	      itcl::find objects ::*
