Linux File Management and Permissions

Start with file operations

For an introduction to directory creation, start with the mind map on creating, moving and copying directories and files. It includes the mkdir command, an option for setting permissions on a new directory and an option for creating parent directories. Then look at the Linux Basic File Operations mind map alongside it.

The Useful commands note gives you examples to work through, including commands for listing file attributes and finding a file by name. Keep it open while you study the maps so you can connect the command examples with the operations they describe.

Study file permissions

The File Permissions mind map shows how to use ls -l to view permissions for files in the current directory. Another mind map in the collection introduces symbolic and numeric permission notation. A note made from that map also covers file permissions, shell scripts and exit status codes.

Study the permissions maps first, then use the quiz on managing file ownership and permission to check what you remember. Return to the maps when a question points you back to a notation or command you want to review.

Explore the file system

Chapter 4 Notes introduces the Filesystem Hierarchy Standard and the location of files and directories. Linux File System also discusses the recommended file system hierarchy. For command recall, the Linux LP1 Chapter 7 flashcards ask about locate and its database.

A Linux quiz in the collection includes questions about the /tmp directory, hosts and user IDs. It offers another way to work with material around the file system after reading the notes.

Use the wider unit

This topic is part of a wider system administration unit in Computing and ICT. Its maps and notes provide reference material, while its flashcards and quizzes give you questions to work through. Choose a map and a quiz to use together as you study.
