00:00:04,410 --> 00:00:08,830
In the previous few lectures, we have talked about the comments and I explain to you what is difference

2
00:00:08,830 --> 00:00:15,190
between options and arguments, and of course, you could use multiple options and the multiple arguments

3
00:00:15,190 --> 00:00:21,110
in every single command in order to find out to which options are supported by a specific amount.

4
00:00:21,430 --> 00:00:27,220
You need to enter eyes or mom and comment or comment and does that help option.

5
00:00:27,490 --> 00:00:31,360
In such case, you will see a list of all available options you are able to use.

6
00:00:32,020 --> 00:00:37,270
Also, you could find out which arguments are mandatory and which are optional.

7
00:00:37,870 --> 00:00:39,310
All right, now let's proceed.

8
00:00:39,400 --> 00:00:45,820
And let me now talk about processes and you'll understand that basically when you enter each command,

9
00:00:46,090 --> 00:00:47,980
you start a specific process.

10
00:00:48,520 --> 00:00:50,110
And there are different processes.

11
00:00:50,200 --> 00:00:54,520
There are processes that simply quickly start and afterwards they're stopped.

12
00:00:54,730 --> 00:00:56,710
For example, when you enter L.

13
00:00:56,770 --> 00:01:05,230
S or MTD argument, you start corresponding LSC or MCE diaper us and those processes do their job and

14
00:01:05,260 --> 00:01:06,820
afterwards they simply stop.

15
00:01:07,420 --> 00:01:14,680
Also, there are so-called the long run processes like Barsh Shell brought us or CHL process and so

16
00:01:14,680 --> 00:01:14,830
on.

17
00:01:15,370 --> 00:01:18,080
I'll talk about all of that in this and next lectures.

18
00:01:18,310 --> 00:01:19,040
Let's get started.
