If \fInewName\fR is an empty string then \fIoldName\fR is deleted. \fIoldName\fR and \fInewName\fR 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 \fBrename\fR command returns an empty string as result. .SH EXAMPLE The \fBrename\fR 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 \fBsource\fR command is called: .CS \fBrename\fR ::source ::theRealSource set sourceCount 0 proc ::source args { global sourceCount puts "called source for the [incr sourceCount]'th time" uplevel 1 ::theRealSource $args } .CE .SH "SEE ALSO" namespace(n), proc(n) .SH KEYWORDS command, delete, namespace, rename
