That's news to me. I was under the impression that /etc/alternatives
is the mechanism by which "rename" can be used for two different
commands, prename and file-rename, which would otherwise collide
with the name /usr/bin/rename.
(I realise that, as of stretch, one of these versions of rename becomes
deprecated and will be withdrawn in future, but it's the example that
comes immediately to mind because they've been around for many years.)
$ rename
Usage:
rename [ -h|-m|-V ] [ -v ] [ -n ] [ -f ] [ -e|-E perlexpr]*|perlexpr
[ files ]
$ rename # having just removed package rename
Deprecated program in use: rename as shipped with the Debian perl
package will be removed after the release of stretch. Please install
the separate 'rename' package which will provide the same command.
Usage: rename [-v] [-n] [-f] perlexpr [filenames]
$
Cheers,
David.
