Lab: Mount File Systems and Find Files

Note lab.

In this review, you mount a file system and locate files based on different criteria.

Outcomes

Mount an existing file system.

Find files based on their file name, permissions, and size.

If you did not reset your workstation and server machines at the end of the last chapter, then save any work that you want to keep from earlier exercises on those machines, and reset them now.

As the student user on the workstation machine, use the lab command to prepare your system for this exercise.

This command prepares your environment and ensures that all required resources are available.
