00:00:00,090 --> 00:00:01,290
Hello, you beautiful person.

2
00:00:01,290 --> 00:00:07,020
And welcome to this very exciting section of the course all about automating tasks, using batch scripts

3
00:00:07,020 --> 00:00:07,980
and cron.

4
00:00:07,980 --> 00:00:12,810
Now, up until now you've been learning how to do commands one after the other on the command line.

5
00:00:12,810 --> 00:00:17,250
But sometimes, however you want to complete tasks that require multiple steps.

6
00:00:17,250 --> 00:00:22,200
So instead of just memorizing the steps and entering those steps, those command steps, every single

7
00:00:22,200 --> 00:00:26,700
time you need to complete that task, you can instead write those commands into a text file known as

8
00:00:26,700 --> 00:00:29,040
a batch script, and then just run the script.

9
00:00:29,490 --> 00:00:35,400
And when you run the script, each of the commands in the script will be run one after the other from

10
00:00:35,400 --> 00:00:36,000
top to the bottom.

11
00:00:36,000 --> 00:00:40,620
So the shell will start at the top of the script and work its way down through the script, executing

12
00:00:40,620 --> 00:00:42,750
all of the commands on the way.

13
00:00:42,840 --> 00:00:43,200
All right.

14
00:00:43,200 --> 00:00:48,630
So in this section of the course, you're going to learn how to create and run your very own batch scripts,

15
00:00:48,630 --> 00:00:53,640
but you're also going to see how you can schedule those commands and batch scripts to be run at certain

16
00:00:53,640 --> 00:00:57,810
times using a really handy scheduling program called Cron.

17
00:00:57,810 --> 00:01:02,730
Now, batch scripting is a whole massive field in and of itself, so this won't be an overly detailed

18
00:01:02,730 --> 00:01:03,480
section of the course.

19
00:01:03,480 --> 00:01:07,920
But I hope that by the end of the session you'll have the fundamental concepts and understanding of

20
00:01:07,920 --> 00:01:11,820
what batch scripting is all about so that you can start writing your own simple scripts.

21
00:01:11,820 --> 00:01:17,550
You'll also know how to schedule and automate commands and scripts to run at any time you choose by

22
00:01:17,550 --> 00:01:18,510
using cron.

23
00:01:18,510 --> 00:01:23,520
So again, combining these two skills will allow you to truly set your workflow on autopilot.

24
00:01:23,520 --> 00:01:27,690
So now that you've got a quick heads up about what's going to be covered in this section, let's jump

25
00:01:27,690 --> 00:01:31,950
right in in the next video by learning how to write your very own batch scripts.
