Files and File Systems

Everything in a Linux system is a file. Hence, understanding the file system is important in becoming more proficient at navigating the system. In this chapter, we will look further into what files are, how they are represented, and the layout of the file system. This is a continuation of topics introduced earlier in Section 3.3 from Chapter 3. Furthermore, we will look at file security and permissions, some common file system operations and also look under the hood at devices and partitions, where file systems are physically stored.
