The book you hold now, UNIX Filesystems: Evolution, Design, and Implementation, is the first book to cover filesystems from all versions of UNIX and Linux. The author gives you details about the file I/O aspects of UNIX programming, describes the various UNIX and Linux operating system internals, and gives cases studies of some of the most popular filesystems including UFS, ext2, and the VERITAS filesystem, VxFS. The book contains numerous examples including a fully working Linux filesystem that you can experiment with. Our commitment to you does not end at the last page of this book.
