Quizzes and tests may refer to work done in this Worksheet and Assignment; save your answers. You will use a checking program at the end of the assignment to verify the correctness of your work. You must upload the check program results before the due date. Before you get started - REMEMBER TO READ ALL THE WORDS You must have your own Fedora 12 virtual machine (with root permissions) running to do this lab. You cannot do this assignment on the Course Linux Server because you do not have root permissions on that machine. Disks, Partitions, and File Systems 1 Commands, topics, and features covered Use the on-line help (man command) for the commands listed below for more information. ➢ df – show mounted partitions and amount of used/free space ➢ du – recursively display disk usage in directories ➢ eject – unmount and eject a CDROM ➢ fdisk – to display, create, delete, and manage partitions; option -l is very useful ➢ file – determine what kind of thing a pathname is. Can show partition file system types using option -s and will follow (dereference) symbolic links using option -L (upper case) ➢ mkfs – create a file system on a device, usually a hard disk partition. ➢ mkswap – initialize a partition for use as a Linux swap partition. ➢ mount – mount a file system existing on some device into the main file system tree. ➢ swapon – tell the Linux kernel to use an initialized swap partition.
