Directories are special files, hence they have inodes. You can test that with ls: ls -li or using stat: stat -c '%F : %i : %n' * Example: % stat -c '%F : %i : %n' * regular file : 670637 : bar.csv regular file : 656301 : file.txt directory : 729178 : foobar The number in the middle is the inode number.
