It's also worth noting that hard links are "harder" to view and find compared to symbolic links (symlinks) and are primarily used for administrative instead of user purposes. Modern terminals display symlinks with colour, the -F option to ls appends @ to symlinks, and the -l option displays the target.

Hard links are only indicated by a link count >1 for files, but to find them, you must search by inode number (since they all share the same inode number) - e.g., ls -i to list inode numbers, and find / -inum 1234 (for inode 1234) to find them on the same filesystem.

It's not a POSIX standard, but most implementations of find support "-samefile" as a more straightforward shortcut, like:

find / -samefile /path/to/some/hard/link
