In fact, we can see the total number of times that inode 5120 is referenced
by using the ls -dl command:
$ ls -dl /usr/local
drwxr-xr-x 8 root root 240 Dec 22 20:57 /usr/local
If we take a look at the second column from the left, we see that the
directory /usr/local (inode 5120) is referenced eight times. On my system,
here are the various paths that reference this inode:
/usr/local
/usr/local/.
/usr/local/bin/..
/usr/local/games/..
/usr/local/lib/..
/usr/local/sbin/..
/usr/local/share/..
/usr/local/src/..
