Also,it's worth noting that inodes represent the file, not the path to
the file.  In UNIX filesystems a given file may appear under multiple
pathnames.  Aside from the standard "." and ".." entries in
directories, hard links aren't much used, so it's not likely to be a
problem in practice, but worth knowing.

Example:

$ echo Hello >hello1.txt
$ ln hello1.txt hello2.txt
$ cat hello2.txt
Hello
$ ls -1i hello?.txt
7128053 hello1.txt
7128053 hello2.txt
$ echo goodbye >hello2.txt
$ cat hello1.txt
goodbye
