- Hello, and welcome to Lesson 10.

00:00:09,390 --> 00:00:10,410
In this lesson, you'll learn

3
00:00:10,410 --> 00:00:12,540
about Linux permission management.

4
00:00:12,540 --> 00:00:15,000
I'll start by explaining
the basic read, wright,

5
00:00:15,000 --> 00:00:17,940
and execute permissions
and how to apply them.

6
00:00:17,940 --> 00:00:19,930
Next, we'll cover the
advanced permissions,

00:00:19,930 --> 00:00:22,830
SUID, SGID and sticky bit,

00:00:22,830 --> 00:00:25,980
which I use in specific situations only.

00:00:25,980 --> 00:00:28,500
Following that, I'll explain the umask,

00:00:28,500 --> 00:00:29,820

00:00:29,820 --> 00:00:32,550
of setting default
permissions on new files.

12
00:00:32,550 --> 00:00:34,830
