File and directory management commands
Once a hierarchy is defined, there is a never-ending need to manage the objects in the filesystem. Objects are constantly created, read, modified, copied, moved, and deleted, so wisely managing the filesystem is one of the most important tasks of a system administrator. In this section, we discuss the basic command-line utilities used for file and directory management. There are GUI tools for this task, but the LPI Level 1 exams only test on command-line tools, and although GUI tools are sometimes more intuitive, a good system administrator should always be always be able to administer his or her system from the command line.
