Welcome to another video of Section. 1 course, 2 00:00:10.300 --> 00:00:13.200 introduction allowed set up. This is the third video of 3 00:00:13.200 --> 00:00:16.100 the section 1 introduction to Linux is gripping that 4 00:00:16.100 --> 00:00:19.500 you promised. Before we can have an overview to the links comments for 5 00:00:19.500 --> 00:00:21.300 the people Zoo. This is starting is hanging. 6 00:00:22.800 --> 00:00:25.500 So we wonder how the Linux command 7 00:00:25.500 --> 00:00:28.700 structure works, in Linux command line that 8 00:00:28.700 --> 00:00:31.700 we call terminal. So you're 9 00:00:31.700 --> 00:00:34.300 going to be aware of that. That so we called CMD, no 10 00:00:34.300 --> 00:00:37.300 windows just met or want to know that for 11 00:00:37.300 --> 00:00:41.000 your general knowledge, but we're going to use them later. So 12 00:00:40.400 --> 00:00:42.400 remember these names. 13 00:00:43.500 --> 00:00:46.900 Ellen has come online over, Kurt terminal every comment, identifies 14 00:00:46.900 --> 00:00:49.300 it order or process that you want to 15 00:00:49.300 --> 00:00:53.100 execute the unlocked and Microsoft Windows Samuel. 16 00:00:52.100 --> 00:00:55.700 Powershell Linux is case sensitive. 17 00:00:55.800 --> 00:00:59.000 What is that? We're going to take attention to that after 18 00:00:58.100 --> 00:01:01.100 the slide. So it is important to 19 00:01:01.100 --> 00:01:04.800 mention that you should be aware of the uppercase and lowercase word. 20 00:01:04.100 --> 00:01:07.400 For example, in seemly, you can just type 21 00:01:07.400 --> 00:01:10.400 every comment in uppercase or lowercase 22 00:01:10.400 --> 00:01:12.700 is as important. You can do it and it's 23 00:01:12.800 --> 00:01:15.300 He's going to be wrong. But India. No Linux command line. No, 24 00:01:15.300 --> 00:01:17.300 it's not like that case sensitive. 25 00:01:18.500 --> 00:01:21.600 We're going to sit in our examples. Also, most 26 00:01:21.600 --> 00:01:24.600 common. They specify options or arguments in 27 00:01:24.600 --> 00:01:27.500 case, you don't know how to use all them for 28 00:01:27.500 --> 00:01:30.400 your purpose, or you want to know how to find a specific search. 29 00:01:30.400 --> 00:01:33.100 You can always use a shhh after every comment to 30 00:01:33.100 --> 00:01:37.200 provide you a list of common arguments Dash. H 31 00:01:36.200 --> 00:01:39.300 stands for help H Bar L. 32 00:01:39.800 --> 00:01:42.100 So if Dash H is a 33 00:01:42.100 --> 00:01:45.700 work, just dash dash help. So, 34 00:01:45.700 --> 00:01:47.500 in this cool, see an example of the 35 00:01:47.600 --> 00:01:51.000 Ling's comment. The first commonly, we're going to go have 36 00:01:50.200 --> 00:01:54.200 one over. Really need is a LS common, provide 37 00:01:53.200 --> 00:01:56.300 a listing of available file 38 00:01:56.300 --> 00:01:59.600 names in a current directory of the user. So, 39 00:01:59.600 --> 00:02:00.800 let's see the example. 40 00:02:02.300 --> 00:02:06.100 So here we are in our Linux machine. We're 41 00:02:06.100 --> 00:02:09.200 going to type LS, that's gonna show all the 42 00:02:09.200 --> 00:02:12.700 files in our dietary here is okay. 43 00:02:12.700 --> 00:02:15.100 We can see all the files the in the 44 00:02:15.100 --> 00:02:16.100 path that we are in. 45 00:02:17.400 --> 00:02:20.600 But we'll see what happens when we type LS. Dash. 46 00:02:20.600 --> 00:02:21.300 Cash hell. 47 00:02:22.800 --> 00:02:25.100 Oh, let's see. All the 48 00:02:25.100 --> 00:02:28.600 switches with the explanation of them. So if 49 00:02:28.600 --> 00:02:31.600 you ever curious about any 50 00:02:31.600 --> 00:02:34.500 comment on a Linux, just type cash Edge or 51 00:02:34.500 --> 00:02:37.300 watched as help for that comment after that. And you can see 52 00:02:37.300 --> 00:02:41.200 it's working. You fool common description. Let's 53 00:02:41.200 --> 00:02:44.800 see what's happened. If we have it in uppercase. 54 00:02:46.200 --> 00:02:50.200 L as in a capital or it's not working common, 55 00:02:49.200 --> 00:02:52.600 and not found, but it is CMD. Let's 56 00:02:52.600 --> 00:02:55.900 go to our CMD. This open a CME here. For 57 00:02:55.900 --> 00:02:58.800 example, when 58 00:02:58.800 --> 00:02:59.500 we type 59 00:03:01.800 --> 00:03:04.600 Vir that's going to work exactly like LS. But 60 00:03:04.600 --> 00:03:07.400 in the same reform can see all the 61 00:03:07.900 --> 00:03:10.500 files in a directory was have what happens if we 62 00:03:10.500 --> 00:03:13.500 just type your in a capital way. It's 63 00:03:13.500 --> 00:03:16.800 going to work again. So you now know the difference but 64 00:03:16.800 --> 00:03:19.400 let's get back to our the next. You see how 65 00:03:19.400 --> 00:03:24.300 LS command Works. Let's get to our back to our PowerPoints in 66 00:03:22.300 --> 00:03:25.600 the second example. 67 00:03:25.600 --> 00:03:28.700 We have LS Dash, L. Comment. That 68 00:03:28.700 --> 00:03:30.600 is plays a listing of available file. 69 00:03:30.900 --> 00:03:33.500 Include all the details about them and the permission 70 00:03:33.500 --> 00:03:36.200 is about them. So why is it exactly? The see 71 00:03:36.200 --> 00:03:39.400 again? Let's get back to our Linux. Here's on 72 00:03:39.400 --> 00:03:41.300 us again. So, let's time. 73 00:03:42.600 --> 00:03:45.400 First, let's be a little clean and 74 00:03:45.400 --> 00:03:49.200 clear. We're going to type color here, 75 00:03:48.400 --> 00:03:51.600 but we're going to tell you a shortcut later 76 00:03:51.900 --> 00:03:54.800 to help clear your screen and Linux, 77 00:03:54.600 --> 00:03:57.600 but for now just 78 00:03:57.600 --> 00:04:01.300 use a clerical meant to know your Columbia. Interface 79 00:04:00.400 --> 00:04:04.100 what LS 80 00:04:03.100 --> 00:04:06.700 Dash L is happening when you enter 81 00:04:06.700 --> 00:04:09.300 this command. Okay, we have all the details 82 00:04:09.300 --> 00:04:10.400 about every file here. 83 00:04:11.200 --> 00:04:13.100 for example, the lab that takes the 84 00:04:14.900 --> 00:04:17.600 Time that's created the user net credit 85 00:04:17.700 --> 00:04:20.100 and also the permission of it. They were going to go 86 00:04:20.100 --> 00:04:23.700 through it later in further videos. Well, 87 00:04:23.700 --> 00:04:26.500 it's actually not in our courses that's explain 88 00:04:26.500 --> 00:04:29.700 about the Linux stuff. But maybe 89 00:04:29.700 --> 00:04:33.200 I'm going to court over wheel at a permission Linux to 90 00:04:32.200 --> 00:04:35.200 you know, you have a better view of 91 00:04:35.200 --> 00:04:38.300 what you're doing here. But LS Dash L can 92 00:04:38.300 --> 00:04:39.600 show you all the details about 93 00:04:40.900 --> 00:04:43.300 the falls, the next comment in 94 00:04:43.300 --> 00:04:47.300 PowerPoint. If we get back to it, he's 95 00:04:46.300 --> 00:04:49.300 LF. There's a verse that 96 00:04:49.800 --> 00:04:52.100 is a commented, split hidden files in a 97 00:04:52.100 --> 00:04:55.300 directory. So if you want to see all 98 00:04:55.300 --> 00:04:58.300 the files that include a hidden files sometimes, 99 00:05:00.600 --> 00:05:03.700 They got hidden by purpose or just 100 00:05:03.700 --> 00:05:06.400 hit him because of the system files. So let's get to the Linux and 101 00:05:06.400 --> 00:05:07.000 see why. 102 00:05:08.300 --> 00:05:11.200 Okay, I'm just going to type in LS Dash a and 103 00:05:11.200 --> 00:05:15.200 see what's happened. Okay, we have more filed, more 104 00:05:14.200 --> 00:05:17.500 hidden files. So just 105 00:05:17.500 --> 00:05:20.600 a quick tip, if we follow that install, open Dot the 106 00:05:20.600 --> 00:05:23.500 heat on file. So looking here, 107 00:05:23.900 --> 00:05:25.800 if we type LS. 108 00:05:28.500 --> 00:05:31.700 We see all the files, but without any doubt, but 109 00:05:31.700 --> 00:05:34.100 the fans here that haven't done is a hidden file. So 110 00:05:34.100 --> 00:05:37.300 if you ever see a file that story.it see them 111 00:05:37.300 --> 00:05:40.100 file, you can find it with ALS if you 112 00:05:40.100 --> 00:05:43.600 want to see, you should you eat with that LS? Dash 113 00:05:43.600 --> 00:05:46.400 a. So, let's get back to our PowerPoint again. 114 00:05:46.200 --> 00:05:50.000 Well, you are with another comments. Lots 115 00:05:49.100 --> 00:05:52.200 of comments. That's, we 116 00:05:52.200 --> 00:05:55.400 gonna need it. There is a lot of common analytics or 117 00:05:55.400 --> 00:05:58.100 very difficult ones. You need a list. 118 00:05:58.400 --> 00:06:01.700 Many many hours by at least 24 hours 119 00:06:01.700 --> 00:06:04.400 to let all the things all the colors in your Linux, but 120 00:06:04.400 --> 00:06:07.600 I'm just going to teach you some important moments in 121 00:06:07.600 --> 00:06:10.800 case that you don't know it and you need it in 122 00:06:10.800 --> 00:06:13.400 this course the survival skills. 123 00:06:13.400 --> 00:06:16.300 Bubble Linux. We're going to the Ellis. I 124 00:06:16.300 --> 00:06:19.300 was a shell and stylish L that releasing the 125 00:06:19.300 --> 00:06:23.100 permissions of the file is a term directories. The 126 00:06:22.100 --> 00:06:25.900 next one is a CD. It's also 127 00:06:25.200 --> 00:06:27.700 we have it in the CMB to 128 00:06:28.300 --> 00:06:31.000 What is CD do? Let's go to the Linux. 129 00:06:32.200 --> 00:06:35.300 Basilica man is gonna change your diet or E. 130 00:06:35.300 --> 00:06:38.300 We are terminal. So for example, 131 00:06:38.300 --> 00:06:41.300 in the graphical way, you just going to another file to 132 00:06:41.300 --> 00:06:44.400 another file by clicking on it. But in the terminal 133 00:06:44.400 --> 00:06:47.400 isn't like that. What should I do for 12 with another 134 00:06:47.400 --> 00:06:50.600 directory? Okay, fine director 135 00:06:50.600 --> 00:06:53.600 here. We have downloads here. Okay. I want to go 136 00:06:53.600 --> 00:06:57.200 to the downloads folder. What should I do using CD and 137 00:06:56.200 --> 00:06:58.200 type download? 138 00:07:00.100 --> 00:07:03.600 It's great. Now if you see here, we 139 00:07:03.600 --> 00:07:06.500 are in a downloads directory. So how 140 00:07:06.500 --> 00:07:09.500 do I know which territory am I in? We're going to pay attention 141 00:07:09.500 --> 00:07:12.300 in any further comments. Let's get better 142 00:07:12.300 --> 00:07:16.600 notaries and along the comments that you have. Okay. 143 00:07:16.500 --> 00:07:19.300 We have a pwv here that 144 00:07:19.300 --> 00:07:23.800 shorted, the current directory. Let's go to it. First. Let 145 00:07:23.800 --> 00:07:26.500 me type PWD in and links common line. 146 00:07:26.100 --> 00:07:29.000 We can see them don't win that. We are in. 147 00:07:29.800 --> 00:07:33.200 However, if you want to go back into the actual Devil's under 148 00:07:32.200 --> 00:07:35.100 Dean in the root directory, that is 149 00:07:35.100 --> 00:07:37.600 the main directory of every Linux. 150 00:07:38.900 --> 00:07:40.000 We can type CD. 151 00:07:41.500 --> 00:07:44.600 Double dots and gold dots 152 00:07:44.300 --> 00:07:47.700 is 10 for the parent directories. And 153 00:07:47.700 --> 00:07:50.400 no matter in Mario, and one 154 00:07:50.400 --> 00:07:54.000 go to our, you're in, if you type CD double knot, you're 155 00:07:53.200 --> 00:07:56.600 going to bring back your previous or parents 156 00:07:56.600 --> 00:07:57.800 territory that you are in. 157 00:07:59.600 --> 00:08:01.500 Okay, so let's get to the other commands. 158 00:08:03.200 --> 00:08:06.600 We have our M Dash RF here. What is? That is 159 00:08:06.600 --> 00:08:10.000 removing the directories. So you may Wonder, okay. 160 00:08:09.100 --> 00:08:12.400 We now learn how to move between 161 00:08:12.400 --> 00:08:15.300 the directors. What if I want to delete one, you know, 162 00:08:15.500 --> 00:08:18.300 your windows throughout the right? Click on it and delete, but 163 00:08:18.300 --> 00:08:21.700 it's not, you know, Common line in a window in the Linux 164 00:08:21.700 --> 00:08:23.800 in the like that. So let's get to the terminal. 165 00:08:25.300 --> 00:08:28.300 Okay, what file do we have here is check it out. So 166 00:08:28.300 --> 00:08:31.000 I want to delete, I 167 00:08:31.100 --> 00:08:34.600 don't know. You don't recall the music here. Under 168 00:08:34.600 --> 00:08:37.900 stop RN, pressure. RF music. 169 00:08:37.800 --> 00:08:40.800 That's it LS. 170 00:08:40.600 --> 00:08:42.700 There is no music. 171 00:08:45.200 --> 00:08:48.400 There's no music file here anymore. The music 172 00:08:48.400 --> 00:08:51.300 file. Just tilted with this comment. 173 00:08:52.400 --> 00:08:55.300 Okay. Now we learn on the things about 174 00:08:55.300 --> 00:08:58.600 removing moving to other doctor is showing them. What 175 00:08:58.600 --> 00:09:02.000 if I want to copy the files and 176 00:09:01.100 --> 00:09:04.800 easy with the common EP. 177 00:09:04.200 --> 00:09:07.100 Let's see, for 178 00:09:07.100 --> 00:09:10.500 example, we have a folder, text here 179 00:09:10.600 --> 00:09:12.700 and I don't want to copy it. 180 00:09:14.400 --> 00:09:17.900 If you file that txt to 181 00:09:17.900 --> 00:09:20.700 the file or another. 182 00:09:22.200 --> 00:09:25.300 Name under no path. Txt. 183 00:09:28.300 --> 00:09:29.000 Here it is. 184 00:09:32.800 --> 00:09:34.600 It's have been copied to another name. 185 00:09:35.900 --> 00:09:38.500 In the same directory. Also, 186 00:09:38.500 --> 00:09:41.500 you can bring directories.for example, 187 00:09:41.500 --> 00:09:44.500 when you type CP and you want to copy another 188 00:09:44.800 --> 00:09:47.600 follow. To do know if three, we can just do 189 00:09:47.600 --> 00:09:50.800 this file, the text here and learn what 190 00:09:50.800 --> 00:09:54.200 we will download, and put it in the download directories 191 00:09:53.100 --> 00:09:56.700 and call it file to 192 00:09:56.700 --> 00:09:57.700 Dot txt. 193 00:10:00.500 --> 00:10:03.100 And LS from downloads directory. 194 00:10:05.200 --> 00:10:08.900 If we have this file here, and we committed with a CPN, copy 195 00:10:08.900 --> 00:10:11.200 from the phone texting. All right, 196 00:10:11.200 --> 00:10:15.000 then let's get to the another one, the no comment read, 197 00:10:14.300 --> 00:10:17.500 or create a text box file. Let's say 198 00:10:19.100 --> 00:10:22.200 normal file is going to works for you as 199 00:10:22.300 --> 00:10:26.900 a teacher, you know, for example, in notepad in the windows. So 200 00:10:26.900 --> 00:10:29.700 for example, we type in Nano. Also, 201 00:10:29.700 --> 00:10:33.000 we have another call editorial, 202 00:10:32.100 --> 00:10:35.300 Linux. We I, but 203 00:10:35.300 --> 00:10:38.100 that's a little more professional. That I don't want 204 00:10:38.100 --> 00:10:41.900 to get into the hardest of yet. Just going to keep it easy. So, 205 00:10:41.900 --> 00:10:44.700 not only is, the more, is it in a? We, I so 206 00:10:44.800 --> 00:10:47.500 don't know. Add, for example, Court, 207 00:10:47.500 --> 00:10:48.700 read that you stink. 208 00:10:49.800 --> 00:10:52.500 It's gonna open new window that 209 00:10:52.500 --> 00:10:55.700 we can type in it, anything either. 210 00:10:58.700 --> 00:11:02.700 Bye control X and click 211 00:11:02.700 --> 00:11:05.800 on quick and 212 00:11:05.400 --> 00:11:08.400 enter. It's going to save though. 213 00:11:08.400 --> 00:11:09.300 We have a new. 214 00:11:10.700 --> 00:11:13.500 Text file here code red and 215 00:11:13.500 --> 00:11:14.600 we type something in it. 216 00:11:15.900 --> 00:11:18.500 Next comment is if config that 217 00:11:18.500 --> 00:11:21.600 you cite in the previous videos and 218 00:11:21.600 --> 00:11:25.900 it's going to give us their IP addresses of the machine. The 219 00:11:25.900 --> 00:11:28.700 next one is a ping that 220 00:11:28.700 --> 00:11:31.400 you also selects one, in the previous comments. Do 221 00:11:31.700 --> 00:11:34.100 the pink, the host. The last one 222 00:11:34.100 --> 00:11:38.500 is the who is there? We're going to pay attention to do that, further 223 00:11:37.700 --> 00:11:40.100 videos, and then we're going 224 00:11:40.100 --> 00:11:40.800 to work with it. 225 00:11:42.100 --> 00:11:45.300 To get information about our targets. So as I mentioned and 226 00:11:45.300 --> 00:11:49.000 I promised, I want to give you some shortcuts in 227 00:11:48.000 --> 00:11:49.600 a Linux. 228 00:11:51.100 --> 00:11:54.300 As always, there is a minute shortcuts in the OR digital world that 229 00:11:54.300 --> 00:11:57.800 make our life easier and more productive. Links 230 00:11:57.800 --> 00:12:00.300 always has made the same concept. There 231 00:12:00.300 --> 00:12:03.200 is a minute shortcut that you can help you. And 232 00:12:03.200 --> 00:12:06.400 during the process. We are going to show some of them. And 233 00:12:06.400 --> 00:12:09.500 one of the most important things don't waste your time, which 234 00:12:09.800 --> 00:12:12.800 type in clear, comment there's control L and 235 00:12:12.900 --> 00:12:15.500 Screen gonna clear immediately. The 236 00:12:15.500 --> 00:12:18.500 next one is control you as clear. Common line 237 00:12:18.500 --> 00:12:20.700 immediately does not conduct all the screen. 238 00:12:20.900 --> 00:12:23.400 Going to be there comes going to be dirt, but it's gonna 239 00:12:23.400 --> 00:12:26.600 move you to the next page of it. So control element 240 00:12:26.600 --> 00:12:29.400 and removed. All the comments from the screen but 241 00:12:29.400 --> 00:12:32.500 control you are going to the next page and put the comments are 242 00:12:32.500 --> 00:12:35.200 still there. But our run up 243 00:12:35.200 --> 00:12:38.700 down is going to scroll down between the commons histories. So 244 00:12:38.700 --> 00:12:41.500 if you want to comment that you 245 00:12:41.800 --> 00:12:44.500 type it in there, I don't know 10 minutes ago, 246 00:12:44.600 --> 00:12:47.800 can just do it with the screw lock and scroll down under 247 00:12:47.800 --> 00:12:50.500 control a is moved to the beginning 248 00:12:50.500 --> 00:12:50.700 of the 249 00:12:50.800 --> 00:12:52.700 common line and for the editing. 250 00:12:54.200 --> 00:12:57.300 PostScript over your summary. First, we're going 251 00:12:57.300 --> 00:13:00.300 to Quick brief on Alex command structure then in the 252 00:13:00.300 --> 00:13:03.600 Second Step. So important comments, LSP DVD 253 00:13:03.600 --> 00:13:07.100 CD and they moved on files, copy them and 254 00:13:06.100 --> 00:13:09.500 then after all some reporter 255 00:13:09.500 --> 00:13:12.100 short course of a bitter experience in Linux. 256 00:13:13.400 --> 00:13:16.600 The next video is going to be a section 2 257 00:13:16.600 --> 00:13:20.200 and will not start nmap Essentials. Finally, 258 00:13:19.200 --> 00:13:22.300 after section one, we've done with 259 00:13:22.300 --> 00:13:25.400 a Linux and basic things. We're going to move it to the end map and 260 00:13:25.400 --> 00:13:28.500 going to explain all the essential and fundamental 261 00:13:28.500 --> 00:13:30.500 things about end up. Good luck.
