Answer 1

Use stator fstat. The structure statthey populate contains the inode number. If the two are connected, the fields st_inomust have the same value.

Since inodes are unique only to the device, you also need to check the device identifier ( st_dev).

Answer 2

stat() fstat() . st_dev st_ino , .

EDIT:

, st_dev, st_ino. , . , stat :

$ stat / /boot | grep Device
Device: 903h/2307d  Inode: 2           Links: 23
Device: 902h/2306d  Inode: 2           Links: 3

inode .

Answer 3

stat() fstat() , st_nlink, , . , , .

Answer 4

You can also use

$ ls -i

It lists the inode number, which is the final unique identifier for the file.
