Inode

ls -li	Shows file inode numbers
find / -a -inum 74653	Find all files with associated inode number
find / -a -samefile /usr/bin/dispuid	Find all files that are the same (same inode)

Find file by its inode number.

Use with caution. This method allows modifying the raw filesystem data.

debugfs /dev/<filesystem> ls -i <inode_number>
