Hello everybody and welcome to this

tutorial.

2

Today I will introduce you to the Linux terminal

3

and show you some of its basic

functionalities so

4

So in Kali Linux, the terminal icon is located in the upper left corner

5

this black thing

6

So just click on it

7

and there you go.

8

You have the terminal up and running here by default

9

It opens up a root terminal in Kali

10

So if you want to

11

usually people want to configure it

12

but if you don't want to configure anything else

13

this is perfectly fine.

14

You don't actually need to do anything else.

15

However, 99% of time people will configure the terminal

16

to suit their own needs and purposes.

17

For example, I will always almost always increase the font size.

18

So that it's clear and visible

19

and that I have a better overview of what I am doing at the moment

20

and it also reduces eyestrain, according

to some articles

21

Anyway, just go ahead and right click anywhere on the terminal itself

22

not on the bar, but on the terminal itself

23

and then you have "show menu bar"

24

Now we can see it here

25

Go ahead and click on edit

26

You can click on profiles as well

27

and create new profiles here by just clicking on "New"

28

giving it a name and then configuring it in the preferences.

29

However, we're gonna be configuring the default profile

30

since there really is no need to create any additional ones.

31

Go ahead and click on profile preferences

32

and here you have a great deal of options.

33

One of the first ones you will see

34

is that you can use a system fixed with

font.

35

So this is not good.

36

You see this is very small

37

I always need to change that.

38

If that's fine for you, you can keep it like that

39

but I always change it.

40

I have monospace 20

41

If you click on it, you can change the

font size here if you wish.

42

You can change the font that you're using

43

and that would be it as far as this place is concerned.

44

You has some other very simple options here

45

It says "show menu bar by default in new terminals"

46

I generally take it.

47

I think it's a good idea

48

since you always need to do something like open up a tab

49

or something of a kind

50

but you don't need to

51

You have the cursor shape here.

52

It says "Block" "I-Beam" "Underline

53

I just want to show you how it looks like.

54

You can view the terminal as the changes are applied.

55

So you have a block and you have a underline.

56

I prefer a block

57

You can use whatever you wish.

58

It will not affect you in any technical

sense, that is.

59

I have "Title and Command' and we don't actually change anything there.

60

You can change the title if you wish

61

and we have colors.

62

So I think that this color scheme is appropriate and fitting for me

63

but you can change it anyway you like.

64

You can customize it to the point of extreme.

65

You can change the text color.

66

The background color.

67

You have the color palette here.

68

So you can do whatever you want here.

69

You have built-in schemes.

70

It says White on Black

71

I can say Green on Black

72

Oops, sorry...cancel

73

You can say Green on Black

74

Does it have Blue on Black?

75

Umm, no.

76

Oh, this one's bad

77

I wouldn't be able to work on this one.

78

So let's just leave it at White on Black.

79

This is the best color...

80

This is one of the best color schemes I use.

81

Personally, I use on Fedora Blue on Black

82

but I'm just gonna leave it as it is here.

83

No need to actually change anything.

84

Now in the background, you have three features here basically

85

You have solid color like this one here that you are seeing

86

and you can choose a background image.

87

You can download anything you want from the internet pretty much.

88

You can configure it to be transparent

89

or image background.

90

and also, you have the ability to have a fully transparent background

91

and if you click on "Transparent Background"

92

it's pretty much the same as having a background image

93

except in this case

94

excellent

95

I'm just gonna configure the transparency levels

96

and that's pretty good

97

except in this case

98

your background image will be your desktop image pretty much

99

depending on where your terminal is.

100

in "Scrolling", there's an important

feature here

101

It's "Scroll Back"

102

So you don't want to have 512 lines.

103

You want to go ahead and click on "Unlimited"

104

unless you're severely limited in terms of RAM

105

and unless you're typing in a large amount of commands

106

or something of a kind

107

but in any case, it's better to have unlimited

108

especially not only environment such as these

109

but rather instead

110

in cases such as these.

111

You don't need to do anything here in terms of compatibility.

112

I'm just gonna go ahead and close this

113

and I have selected a transparent background

114

and you see this only works for a desktop image.

115

It doesn't actually show icons or anything of the kind.

116

If I open up my web browser, it's not gonna show it in the background.

117

It's still gonna keep the desktop background image.

118

So the desktop wallpaper, should you wish to call it so.

119

There's a slight delay when it goes about in the update

120

but it's fine.

121

Doesn't bother us in this slightest bit.

122

Maybe I will change this later on during tutorial

123

see how I like it

124

but I just wanted to give you an option, so you can do whatever you want with it.

125

In any case, you can go ahead and click on "File"

126

and "Open Tab"

127

I'm just gonna go ahead open myself four tabs

128

three new ones and one I already had.

129

So here you can switch in between them.

130

It's very nice.

131

There are no complications.

132

For example, if I press "Open up a new terminal"

133

I gotta click here and then I gotta click here

134

and unusually you're gonna have...

135

I'm just wanna show you what it's like to have four of them.

136

So yeah, this is not actually manageable

137

especially because you don't know what you are doing on which terminal.

138

People sometimes split their screens into terminals.

139

I sometimes do that

140

It's very nice

141

but we will deal with that a bit later on when we get into some serious stuff.

142

When we actually need multiple terminals

143

but tabbing these terminals

144

it's very nice

145

primarily because you can actually see what you're doing

146

on each one of them in the headers.

147

See these things that I'm clicking on now

148

They are headers of the terminal

149

or so you can call them

150

and for example, in this terminal

151

I'm gonna go ahead and say

152

"I want you to go into home. Change the

directory to home"

153

Change the working directory, that is

154

If I change it here to "var"

155

and if I change it here to "var/logs"

156

and if I want to go here to "tmp folder"

157

Excellent

158

So on each of the tabs in the headers

159

I can see where I am.

160

So this this one, it's home

161

but this one, it's tmp.

162

I don't need to click on it to know.

163

This one is log.

164

So I can know what I'm doing in every particular terminal

165

and even though you could have a program running

166

or something like that

167

It's still gonna write it out in the header

168

and you're gonna get some extra information there.

169

It's very nice

170

It's very useful

171

and it's going to help you out a lot as we progress through this course

172

and as we get into more complicated

stuff.

173

Anyway, I just want to introduce you to the next terminal.

174

We have done some work with before

175

during the installation of VirtualBox and VirtualBox guest additions

176

but basically there, I just give you the

command

177

and you're gonna basically just rewrite it or copy-paste it

178

and that's gonna be it.

179

but here, in the follow-up tutorial

180

actually I will start explaining the fundamental Linux terminal commands

181

The most common ones

182

The most basic ones

183

and there you will be able to see the logic of things

184

and how this Linux terminal works and functions

185

because once you actually learn that

186

it gives you a huge amount of power.

187

All the power of the operating system rests on it's terminal

188

because it's a direct interface to the kernel of the system

189

and it's a lot faster then the graphical interface.

190

Now one more keynote that I would like to make here

191

Once I teach you how to use the Linux terminal

192

and once you get into the habit of typing in commands

193

you can use them for a wide variety of

purposes.

194

You don't necessarily need to use these things for pen testing

195

or something like that.

196

You can use these commands for network administration

197

or you can use them in order to troubleshoot problems with the system

198

and so on and so forth.

199

So you get a far wider spectrum options in terms of jobs

200

or something of a kind

201

as opposed to just learning something

that you can only use for pen testing

202

and nothing else.

203

In any case, I bid you farewell

204

and I hope to see you in the next tutorial.
