In this section, we take a look at what Linux file links are and how to work with them. As you already might know, files are stored on the hard disk. In a Linux filesystem, the file's filename and the data are two separate concepts and are not stored together. A general structure is shown in the following diagram:
Connecting a filename to the actual data is managed by the filesystem using a table or database data structure, which is called a title allocation table. In the Linux filesystem, an Inode is the actual entry point or starting point to the beginning of a specific file's data on the hard disk. To simplify, we can just say that the Inode represents the actual data of a file. The filesystem management now takes care that every normal file, upon creation, has one link entry in its allocation table to connect the actual filename to the Inode...
