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.
