Files and Directories
Disk drives divided into partitions
Each partition contains a filesystem (type df for a listing of filesystems mounted on any given computer)
Filesystems are mounted onto existing filenames (Fig 8.4, p.241)
Each filesystem has a boot block, a super block, an ilist containing inodes (short for index nodes), directory blocks, and data blocks
An inode contains all the information about a file: type, time of last modification/write/access, uid/gid of creator, size, permissions, etc.
Directories are just lists of inodes (2 files automatically created with mkdir: “.” (inode of directory) and “..” (inode of parent directory)
See figure 8.3 (page 240) for an example.
