Which type of file will have different inode number than the original file?
Soft Links can be created across file systems. Soft link has a different inode number than the original file. On deleting the original file, soft link cannot be accessed. Soft link needs extra memory to store the original file name as its data.
Which creates a new inode number?
Hard link is an interesting concept. If you have read the above explanation about Inode and inode numbers, you would know that each file is identified by a unique number called inode number. Now, a hard link creates a link to the orignal inode number.
Does symbolic link create inode?
A symbolic link has its own inode number. When you create a symbolic link, you create a new physical file with its own inode number, as shown in Figure 1. Because a symbolic link refers to a file by its path name rather than by its inode number, a symbolic link can refer to files in other mounted file systems.
Why do all files have the same inode number?
Each file in a filesystem has a unique inode number. Inode numbers are guaranteed to be unique only within a filesystem (i.e., the same inode numbers may be used by different filesystems, which is the reason that hard links may not cross filesystem boundaries). Not the answer you’re looking for?
How to find two files with the same Dev number?
If two directory entries have the same inode and dev number, they refer to the same file (though possibly through two different mounts of a same file system for bind mounts). Some find implementations also have a -samefile predicate that will find files with the same device and inode number.
How to check that two files refer to the same file?
Most [ / test implementations also have a -ef operator to check that two files paths refer to the same file (after symlink resolution though). Yes, the same inode number may appear at a different filesystem.
How are inodes unique on a partition level?
Inodes are only unique on a partition level, not on the whole system. On each partition, there is a superblock. This superblock tells the system which inodes are used, which are free, etc (I’ll spare you the technical details).
