rename(n)		     Tcl Built-In Commands		     rename(n)

______________________________________________________________________________

NAME
       rename - Rename or delete a command

SYNOPSIS
       rename oldName newName
_________________________________________________________________

DESCRIPTION
       Rename  the  command  that  used to be called oldName so that it is now
       called newName.	If newName is an empty string then oldName is deleted.
       oldName and newName may include namespace qualifiers (names of contain‐
       ing namespaces).	 If a command is renamed into a	 different  namespace,
       future invocations of it will execute in the new namespace.  The rename
       command returns an empty string as result.

EXAMPLE
       The rename command can be used to wrap the standard Tcl	commands  with
       your  own  monitoring  machinery.  For example, you might wish to count
       how often the source command is called:
	      rename ::source ::theRealSource
	      set sourceCount 0
	      proc ::source args {
		  global sourceCount
		  puts "called source for the [incr sourceCount]'th time"
		  uplevel 1 ::theRealSource $args
	      }
