You're confusing perl-rename with util-linu rename.  The former,
which seems to be what you want, can be installed using cpan
(install File::Rename), assuming you have perl installed.  It
will put its rename command in /usr/local/bin, presumably taking
precedence over the util-linux one in /usr/bin.  It further seems
that "normally" these two have different names, like rename.ul
and prename, and /etc/alternatives is used to set up the rename
command.

This required some web searching to determine ...
