How can I colorize hardlinks myself? Turns out on an old Ubuntu 10.04 I have, this happens by default (same .bashrc and .profile in use), whereas on the newer Ubuntu 12.04 it doesn't.

This is the output on Ubuntu 10.04 (the one I desire):

And this is the output on Ubuntu 12.04:

The relevant file is .vimrc, however, .viminfo is an ordinary file with link count 1, in contrast to the hardlinked .vimrc.

Of course the fact that GNU coreutils uses texinfo pages instead of man pages doesn't make things easier. I found this here, but it doesn't refer to the case I am looking for.

TL;DR: how to achieve coloring hardlinked (as in: link count > 1) files the way I like in various Ubuntu versions.
