- Welcome to lesson six.

This lesson is about
advanced textile processing.

3
00:00:12,300 --> 00:00:14,640
We'll start by having
a look at cut and sort,

4
00:00:14,640 --> 00:00:16,740
and how they can be combined in pipes

5
00:00:16,740 --> 00:00:18,630
to make them really powerful.

6
00:00:18,630 --> 00:00:21,540
Next, you'll get an introduction
to Regular Expressions,

7
00:00:21,540 --> 00:00:23,520
the advanced patterns that are useful

8
00:00:23,520 --> 00:00:25,890
with many tools that deal with text.

9
00:00:25,890 --> 00:00:27,690
You'll learn how to use them with grip,

10
00:00:27,690 --> 00:00:30,270
and after that, we'll have a look at tr

11
00:00:30,270 --> 00:00:32,790
and the advanced tools, awk and sed.

12
00:00:32,790 --> 00:00:34,710
As in all lessons at
the end of this lesson,

13
00:00:34,710 --> 00:00:36,780
you'll find a list of
all commands learned,

14
00:00:36,780 --> 00:00:39,183
as well as the end of
lesson lab and solution.
