After installing Debian 8, I started poking around /bin (as I'm always wont to do), and I noticed that
vdir share, not only the same manpage (except for the
whatis line), but the exact same compiled size. The only thing they don't have in common is the inode number (which seems inefficient, but that's tangential).
Is there any reason for this? What's the historical precedent? Why would we want to have both?
I'd never ever heard of
vdir before today, so it can't be immensely common, and it seems like it should be easy to simply have
vdir be a script that calls
ls with the correct arguments.
