File and Directory Permissions

In this video we'll make a new folder named /srv/www. Then we'll explore the permission bits for the folder and a new file we create. You'll learn about the owner and group and the three permission bits: read, write and execute. You'll also see two additional permission types: 's' and 't' which are the setuid/setgid and the sticky bit respectively. Finally, you'll see how these permissions can be represented as octal numbers.
