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 }


SEE ALSO
