I think it would be nice to have some of these, just to show people the possibilities and give some conceptual explanation that won't really be in a reference manual. Self-esteem booster for the newbie. What and why Automate simple tasks. However, the inode is not directly visible. Instead, each inode is linked into the filesystem by one or more hard links .
Hard links contain the name of the file, and the inode number.
The inode contains the file itself, i.e., the location of the information being stored on disk, its access permissions, the type of the file, and so on. The system can find any inode once it has the inode number. A single file can have more than one hard link. This is because each filesystem has its own set of inodes, and there can be duplicate inode numbers between filesystems. Since all hard links to a given inode are referring to the same file , you can make changes to the file, referring to it by one name, and then see those changes when referring to it by a different name.
