00:00:00,300 --> 00:00:03,870
‫-: Hi, within this lecture we are gonna focus on moving,

2
00:00:03,870 --> 00:00:06,540
‫deleting the files and folders

3
00:00:06,540 --> 00:00:08,970
‫in order to master the navigation.

4
00:00:08,970 --> 00:00:11,700
‫So, right now I'm gonna go into the documents.

5
00:00:11,700 --> 00:00:15,600
‫Okay, and if I write ls, I can see that notes.txt

6
00:00:15,600 --> 00:00:18,840
‫and test and test2 folders are over here.

7
00:00:18,840 --> 00:00:21,930
‫Obviously, can create your own files and folders

8
00:00:21,930 --> 00:00:23,880
‫in order to test this stuff.

9
00:00:23,880 --> 00:00:28,140
‫So we are obviously inside of /home/kali/documents, right?

10
00:00:28,140 --> 00:00:30,720
‫And I know that there are other folders

11
00:00:30,720 --> 00:00:33,180
‫inside of /home/kali.

12
00:00:33,180 --> 00:00:37,170
‫Right, because I can see them like downloads, music,

13
00:00:37,170 --> 00:00:39,570
‫pictures public and stuff.

14
00:00:39,570 --> 00:00:43,320
‫So assume that I wanna put the notes.txt

15
00:00:43,320 --> 00:00:46,470
‫into test folder, okay.

16
00:00:46,470 --> 00:00:51,270
‫So maybe I want to move it, maybe I want to copy it.

17
00:00:51,270 --> 00:00:53,520
‫I can do both by cutting

18
00:00:53,520 --> 00:00:55,770
‫or copying the thing over here, right.

19
00:00:55,770 --> 00:00:59,790
‫Because it's just GUI, it's very basic to do so.

20
00:00:59,790 --> 00:01:00,990
‫And you know how to do that

21
00:01:00,990 --> 00:01:04,200
‫from Windows and other operating systems.

22
00:01:04,200 --> 00:01:07,410
‫But idea over here is to learn how to do that

23
00:01:07,410 --> 00:01:08,880
‫within the terminal.

24
00:01:08,880 --> 00:01:13,170
‫And it appears that the commands to do that are very easy.

25
00:01:13,170 --> 00:01:16,350
‫Like there are two commands, cp and mv.

26
00:01:16,350 --> 00:01:21,000
‫cp stands for copying, mv stands for moving.

27
00:01:21,000 --> 00:01:23,760
‫Okay, so moving is like cutting the file

28
00:01:23,760 --> 00:01:27,420
‫and pasting into something else like some other folder.

29
00:01:27,420 --> 00:01:29,940
‫And copying is just copying the file

30
00:01:29,940 --> 00:01:32,700
‫and pasting in some other folder.

31
00:01:32,700 --> 00:01:34,500
‫So we're gonna see both.

32
00:01:34,500 --> 00:01:38,520
‫Let's assume that I wanna copy the notes.txt

33
00:01:38,520 --> 00:01:41,100
‫into the test folder, okay.

34
00:01:41,100 --> 00:01:44,637
‫So I can do that, copy notes.txt

35
00:01:44,637 --> 00:01:48,450
‫but I can't do that because I'm inside of the documents.

36
00:01:48,450 --> 00:01:52,410
‫If I run ls, I can see notes.txt.

37
00:01:52,410 --> 00:01:55,830
‫Let's assume that I want to do that

38
00:01:55,830 --> 00:01:57,870
‫from another folder.

39
00:01:57,870 --> 00:02:00,450
‫Let's assume that I'm inside of the downloads

40
00:02:00,450 --> 00:02:03,150
‫but I still want to copy the notes.txt

41
00:02:03,150 --> 00:02:05,010
‫inside of the documents.

42
00:02:05,010 --> 00:02:07,650
‫So maybe I can explicitly state

43
00:02:07,650 --> 00:02:12,650
‫that it's /home/kali/documents/notes.txt, okay.

44
00:02:13,140 --> 00:02:15,240
‫But since I'm inside of the documents,

45
00:02:15,240 --> 00:02:19,230
‫I can just do that copy, notes.txt.

46
00:02:19,230 --> 00:02:23,430
‫All I gotta do is just to state where I want to copy this.

47
00:02:23,430 --> 00:02:26,640
‫So I want to copy this inside of the test folder.

48
00:02:26,640 --> 00:02:29,670
‫And also I want to state the file name

49
00:02:29,670 --> 00:02:34,200
‫that I will be copying, like test/notes.txt, okay.

50
00:02:34,200 --> 00:02:37,770
‫I can just state another file name here as well

51
00:02:37,770 --> 00:02:41,790
‫but I'm just gonna keep it as notes.txt.

52
00:02:41,790 --> 00:02:46,790
‫So you can write copy notes.txt at the right side

53
00:02:46,830 --> 00:02:50,730
‫if you want to rename this while copying, okay.

54
00:02:50,730 --> 00:02:54,270
‫So if I run that, it'll just execute this command

55
00:02:54,270 --> 00:02:57,990
‫and it will put the notes.txt, copy the notes.txt,

56
00:02:57,990 --> 00:03:00,720
‫and paste it under the test folder.

57
00:03:00,720 --> 00:03:04,680
‫So let's do that and let's cd into,

58
00:03:04,680 --> 00:03:05,610
‫let me run ls.

59
00:03:05,610 --> 00:03:08,760
‫As you can see, notes.txt is still here.

60
00:03:08,760 --> 00:03:13,320
‫Let me go into the test and if I write ls, here you go,

61
00:03:13,320 --> 00:03:18,320
‫notes.txt just appeared over here because I've copied it.

62
00:03:19,140 --> 00:03:21,210
‫Okay, now we have seen copy.

63
00:03:21,210 --> 00:03:24,420
‫So you write the thing that you may wanna copy

64
00:03:24,420 --> 00:03:28,740
‫and you write the thing that you may want to move that into.

65
00:03:28,740 --> 00:03:31,470
‫Okay, so this is how copy works.

66
00:03:31,470 --> 00:03:33,750
‫So let's see, we are inside of test

67
00:03:33,750 --> 00:03:35,880
‫and we still have notes.txt.

68
00:03:35,880 --> 00:03:38,610
‫Let's assume that I want to delete it.

69
00:03:38,610 --> 00:03:40,350
‫So in order to delete it,

70
00:03:40,350 --> 00:03:45,350
‫I can use rm command which stands for removing, okay.

71
00:03:45,570 --> 00:03:48,180
‫If you execute this command, here you go.

72
00:03:48,180 --> 00:03:52,620
‫You deleted notes.txt, which is cool.

73
00:03:52,620 --> 00:03:56,100
‫Right, all you gotta do is just write this command.

74
00:03:56,100 --> 00:04:00,420
‫Obviously, right now if I write ls, you won't see anything.

75
00:04:00,420 --> 00:04:03,840
‫And obviously, if I go back to the documents

76
00:04:03,840 --> 00:04:05,490
‫I can still see

77
00:04:05,490 --> 00:04:09,330
‫the test that notes.txt over there

78
00:04:09,330 --> 00:04:13,140
‫because I have only deleted the copy of it.

79
00:04:13,140 --> 00:04:16,860
‫And by the way, you don't even have to know everything

80
00:04:16,860 --> 00:04:18,510
‫about this commands.

81
00:04:18,510 --> 00:04:22,860
‫Right, because it's just simple right now.

82
00:04:22,860 --> 00:04:26,010
‫But it may get complicated after a while.

83
00:04:26,010 --> 00:04:30,090
‫And all you gotta do is to understand the logic behind this

84
00:04:30,090 --> 00:04:34,290
‫and maybe you may want to familiarize yourself

85
00:04:34,290 --> 00:04:37,530
‫in order to read documentation.

86
00:04:37,530 --> 00:04:39,960
‫So let me do an example.

87
00:04:39,960 --> 00:04:44,070
‫So I'm going to create a folder over here

88
00:04:44,070 --> 00:04:46,740
‫with rmtest, okay.

89
00:04:46,740 --> 00:04:50,970
‫So I, it's just a folder inside of the test folder, okay.

90
00:04:50,970 --> 00:04:52,080
‫It's just a folder.

91
00:04:52,080 --> 00:04:56,790
‫I can see that when I write ls. I can see the rmtest.

92
00:04:56,790 --> 00:05:01,590
‫Let me try to delete that by removing it, okay.

93
00:05:01,590 --> 00:05:03,840
‫So as you can see, it gives me an error.

94
00:05:03,840 --> 00:05:08,370
‫It says that cannot remove rmtest, it's a directory.

95
00:05:08,370 --> 00:05:12,570
‫So it seems that the rmtest is a folder

96
00:05:12,570 --> 00:05:17,040
‫and we cannot actually delete the folders with rm command.

97
00:05:17,040 --> 00:05:19,410
‫So let me run this,

98
00:05:19,410 --> 00:05:22,620
‫let me run rm help

99
00:05:22,620 --> 00:05:26,250
‫to see the documentation about rm.

100
00:05:26,250 --> 00:05:31,250
‫So rm is actually a binary and like a executable

101
00:05:31,350 --> 00:05:35,040
‫and they all have this documentation.

102
00:05:35,040 --> 00:05:36,960
‫Most of the time you can reach them

103
00:05:36,960 --> 00:05:41,960
‫by adding this --help at the end of the command, okay.

104
00:05:42,150 --> 00:05:46,140
‫So that it can actually show you the documentation,

105
00:05:46,140 --> 00:05:49,980
‫the help module of the rm binary.

106
00:05:49,980 --> 00:05:52,230
‫Okay, if you do that,

107
00:05:52,230 --> 00:05:55,410
‫I'm not even sure if it's going to show us,

108
00:05:55,410 --> 00:05:58,620
‫but if it's not --help,

109
00:05:58,620 --> 00:06:01,350
‫it's something like -h.

110
00:06:01,350 --> 00:06:04,680
‫And as you can see, it shows us the usage,

111
00:06:04,680 --> 00:06:09,680
‫it shows us the different parameters that we can give to rm.

112
00:06:09,990 --> 00:06:12,540
‫And if I take a look over here,

113
00:06:12,540 --> 00:06:15,870
‫there is some parameter called -r,

114
00:06:15,870 --> 00:06:19,080
‫and it says that remove directories.

115
00:06:19,080 --> 00:06:22,710
‫So yeah, maybe I've forgotten how to remove the directories

116
00:06:22,710 --> 00:06:24,150
‫or delete the directories.

117
00:06:24,150 --> 00:06:29,070
‫I can just see that by writing rm --help, okay.

118
00:06:29,070 --> 00:06:32,790
‫For example, there is another parameter over here, -f.

119
00:06:32,790 --> 00:06:37,790
‫It's just deletes the thing with -f with force, okay.

120
00:06:37,980 --> 00:06:41,520
‫So no matter what, it just deletes the thing.

121
00:06:41,520 --> 00:06:44,850
‫So as you can see, rmtest is a folder.

122
00:06:44,850 --> 00:06:49,350
‫And let me write this rm -r and rmtest.

123
00:06:49,350 --> 00:06:50,880
‫And here you go.

124
00:06:50,880 --> 00:06:53,610
‫Now it got deleted.

125
00:06:53,610 --> 00:06:57,150
‫So let me try to create some,

126
00:06:57,150 --> 00:06:59,070
‫let me try to write ls.

127
00:06:59,070 --> 00:07:01,230
‫And here you go, we don't have anything else.

128
00:07:01,230 --> 00:07:04,350
‫Let me just create it one more time

129
00:07:04,350 --> 00:07:07,740
‫and I'm gonna show you rm -rf.

130
00:07:07,740 --> 00:07:11,010
‫And again, this is by force,

131
00:07:11,010 --> 00:07:13,830
‫it means that just delete the thing

132
00:07:13,830 --> 00:07:16,290
‫without thinking anything else, okay.

133
00:07:16,290 --> 00:07:20,250
‫So even if you get like a warning message or error message,

134
00:07:20,250 --> 00:07:21,750
‫just delete the thing.

135
00:07:21,750 --> 00:07:24,720
‫And here you go, it just deletes the thing.

136
00:07:24,720 --> 00:07:27,330
‫Okay, so just bear that in mind.

137
00:07:27,330 --> 00:07:30,363
‫rm -r, rm -rf.

138
00:07:31,350 --> 00:07:33,810
‫So let me go back to documents.

139
00:07:33,810 --> 00:07:36,540
‫As you can see, notes.txt is over here

140
00:07:36,540 --> 00:07:40,380
‫because we have just deleted the copy of it.

141
00:07:40,380 --> 00:07:42,240
‫So let me try and move.

142
00:07:42,240 --> 00:07:45,750
‫Move takes in the arguments exactly like in the copy.

143
00:07:45,750 --> 00:07:48,660
‫So I wanna move that to test2 this time.

144
00:07:48,660 --> 00:07:50,730
‫And here you go. It worked.

145
00:07:50,730 --> 00:07:54,240
‫So I want to move, notes.txt to test2.

146
00:07:54,240 --> 00:07:57,570
‫And as you can see, when I write ls I cannot see it.

147
00:07:57,570 --> 00:08:01,500
‫But if I go to test2, I can see it, okay.

148
00:08:01,500 --> 00:08:03,900
‫That's the difference between moving and copying.

149
00:08:03,900 --> 00:08:06,450
‫So moving is like cutting and pasting.

150
00:08:06,450 --> 00:08:08,910
‫Copying is like copying and pasting.

151
00:08:08,910 --> 00:08:10,980
‫Okay, just bear that in mind.

152
00:08:10,980 --> 00:08:14,040
‫And again, we are doing all of this stuff

153
00:08:14,040 --> 00:08:17,280
‫in order to get familiarized with the terminal.

154
00:08:17,280 --> 00:08:20,670
‫Great, now we started to learn something.

155
00:08:20,670 --> 00:08:24,273
‫I believe we can stop here and continue within the next one.
