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
       containing 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
              }
