Ca dépend:

schaefer@reliand:~$ update-alternatives --display rename
rename - auto mode
  link best version is /usr/bin/file-rename
  link currently points to /usr/bin/file-rename
  link rename is /usr/bin/rename
  slave rename.1.gz is /usr/share/man/man1/rename.1.gz
/usr/bin/file-rename - priority 70
  slave rename.1.gz: /usr/share/man/man1/file-rename.1p.gz

Ici, c'est du Perl.

Les alternatives Debian sont implémentées comme des liens symboliques:

schaefer@reliand:~$ ls -la /usr/bin/rename                             
lrwxrwxrwx 1 root root 24 Sep 10  2020 /usr/bin/rename -> /etc/alternatives/rename

schaefer@reliand:~$ ls -la /etc/alternatives/rename
lrwxrwxrwx 1 root root 20 Sep 10  2020 /etc/alternatives/rename -> /usr/bin/file-rename

schaefer@reliand:~$ file /usr/bin/file-rename
/usr/bin/file-rename: Perl script text executable

Il serait bien d'ailleurs que la manpage suive le même processus, ce qui
est indiqué par l'attribut slave ci-dessus.
