Intro

Navigation and file operations taught you how to move and change things. Now let's learn who can see, change, and run them.

Every file has:

• An owner - who created it
• A group - e.g. developers - all users in that group can access a file
• Permissions for owner, group, and everyone else

You'll learn how to:

• View permissions
• Change permissions
• Change owner
• Understand special permissions
