hard link count

That is, the number of references within the filesystem to the same file.

In unix when the hard link count reaches 0, the space is available (effectively, the file is truly gone).

You can better see this relationship of links (inode references) by adding -i to your ls command. Have some fun exploring. Use ln to create some arbitrary hard links and then do some removes and examine overall space... have fun!
