Disk and file management is critical to installing, securing, and maintaining any server, and a Linux administrator must understand the limits and capabilities of these resources to be effective in planning and building out Linux infrastructure. In this course, you will learn how to configure and manage partition tables, manage filesystems, configure disk quotas, use links, and manage file and directory permissions. You will also be introduced to the Filesystem Hierarchy Standard, or FHS. This course is one of a series in the Skillsoft learning path that covers the objectives for the CompTIA Linux+ exams LX0-101 and LX0-102.
Learning Objectives
Create Partitions and Filesystems
- start the course
- describe how the MBR partition table on a disk can be partitioned and managed
- use various mkfs commands to create filesystems
- identify the features and future of ReiserFS and B-tree filesystems, or Btrfs
- describe the new GUID Partition Table, or GPT, way to partition disks
Maintain the Integrity of Filesystems
- use commands to verify the integrity of a filesystem
- use commands to monitor free space and inodes of a filesystem
- use commands to repair simple filesystem problems
Control Mounting and Unmounting of Filesystems
- perform mount and unmount operations on a filesystem
- configure a Linux system to mount a filesystem on bootup
- describe how to configure user mountable removable filesystems
Manage Disk Quotas
- apply a disk quota to a filesystem
- describe how to edit, check, and generate user quota reports for filesystems with disk quotas enabled
Manage File Permissions and Ownership
- describe the file and directory permissions system in Linux
- use commands to manage user access permissions to regular and special files as well as directories
- use suid, sgid, and the Sticky Bit to maintain security
- configure the default File Creation Mask
- apply access permissions to files and directories for a group
Create and Change Hard and Symbolic Links
- create file and directory links
- describe the differences between soft and hard links
- describe when you should link to a file versus copying a file
- use links to solve some common system administration tasks
Find System Files and Place Files in the Correct Location
- identify the correct locations for files under the Filesystem Hierarchy Standard, or FHS
- use tools to find files and commands on a Linux system
Practice: Working with Devices and Filesystems
- to manage devices and filesystems in Linux
