An inode number stores all the information about a regular file, directory, or other file system object, except its data and name. To find an inode, either use the ls or stat command.

There are two things here. The term INode, and a file-system implementation that uses either INode terminology or something like INode in its place.

Inode Pointer Structure. In the POSIX definition of a file system, there is an item in the inode called an inode pointer structure. Remember that the inode just stores the metadata information including some sort of list of the blocks where the data is stored on the storage media. The inode pointer structure is the data structure universally Hi, I'm reading "Beginning Linux Programming (4th Edition)", published in 2007. In chapter 3 - "Working with files", page 94, they said: "When you delete a file all that happens is that the directory entry for the file is removed and the number of links to the file goes down by one.
