WEBVTT 00:00.560 --> 00:06.200 In this video, I want to go over a quick couple of Linux commands, kind of get you familiar with Linux. 00:06.230 --> 00:12.950 Now, Linux is a wonderful operating system and it does have some GUI based programs. 00:12.950 --> 00:18.560 Meaning if I go to the menu here, I can go to one of these and I can click on one of these and I'll 00:18.560 --> 00:19.790 open a program. 00:19.790 --> 00:26.060 However, if I open most of these, it's going to open up in a terminal window, which is this window 00:26.060 --> 00:30.290 here for windows users, it's basically a command prompt. 00:30.830 --> 00:37.910 Um, Mac users will recognize as a terminal, and we can also open it by going down in here and clicking 00:37.910 --> 00:38.780 this black box. 00:38.780 --> 00:41.180 And it'll say terminal terminal emulator. 00:42.320 --> 00:44.720 And I zoomed in on the terminal here. 00:44.720 --> 00:46.370 If you want to do that yourself. 00:46.640 --> 00:51.500 Hit shift control and the plus key twice and I'll zoom in a little bit. 00:53.000 --> 00:57.500 The other important thing about Linux is Linux is case sensitive. 00:57.500 --> 01:01.970 So if I try to go to a desktop desktop, it has a capital D. 01:01.970 --> 01:04.130 If I do lowercase it's not going to recognize it. 01:04.130 --> 01:08.630 So you do want to pay a very close attention to to things like that. 01:08.780 --> 01:15.230 So a couple things, uh, Linux commands that you want to know is ls that will tell you what directory 01:15.230 --> 01:16.340 you're currently in. 01:16.640 --> 01:19.250 CD is for change directory. 01:19.280 --> 01:20.690 Say I want to go to desktop. 01:20.690 --> 01:21.980 I could do desktop. 01:23.030 --> 01:27.200 And I'm going to intentionally put it all lowercase and show you what's going to happen. 01:27.200 --> 01:28.190 So. 01:28.810 --> 01:30.880 It's going to say no such file or directory. 01:30.880 --> 01:33.760 That's because again, Linux is case sensitive. 01:33.760 --> 01:37.030 So I could do CD space capital D. 01:37.540 --> 01:41.890 And another great thing about Linux is it's uh, it has autocomplete. 01:41.890 --> 01:44.200 So if, if I hit the tab key. 01:46.290 --> 01:51.690 It all finished typing what it thinks I'm going to try to type in so I can do that. 01:51.690 --> 01:55.530 And now I'm in the desktop, I can do LS to show me what's in there. 01:56.310 --> 01:57.120 Okay. 01:57.120 --> 01:59.760 I could do CLS to clear the screen. 02:00.680 --> 02:02.270 Or rather clear. 02:02.420 --> 02:03.380 Sorry. 02:03.920 --> 02:08.480 And if I want to go back, I could do CD space dot, dot. 02:08.480 --> 02:10.460 And that'll take me back directory. 02:10.460 --> 02:12.530 I can do ls again and. 02:13.530 --> 02:14.160 Takes us back. 02:14.190 --> 02:15.870 It shows us everything again. 02:15.870 --> 02:17.760 Another important command is sudo. 02:17.790 --> 02:22.230 Now sudo is basically running things as administrator. 02:22.350 --> 02:29.460 By default, Linux doesn't run things in administrator to give you more protection, so something bad 02:29.460 --> 02:30.150 doesn't happen. 02:30.150 --> 02:32.700 Malware doesn't try to take over your system as easily. 02:33.320 --> 02:39.140 So if we want to run something as a minister, we type in sudo space and whatever the command is and 02:39.140 --> 02:40.310 that's going to run it. 02:42.150 --> 02:44.880 Now we're going to learn a lot of other stuff. 02:45.060 --> 02:47.280 Um, other commands throughout the course. 02:47.280 --> 02:51.600 We're going to be downloading things from GitHub and whatnot, and I'll be walking you through those 02:51.600 --> 02:51.930 commands. 02:51.930 --> 03:01.590 Also, other important commands you want to know are sudo apt get space update. 03:02.400 --> 03:05.070 And that's going to update our operating system. 03:05.070 --> 03:09.420 Likewise we could do sudo apt get. 03:11.610 --> 03:12.510 Upgrade. 03:12.510 --> 03:16.020 And that's going to look for if there's any upgrades to the operating system. 03:16.020 --> 03:19.500 So we don't have to go out and try to look for those updates. 03:19.500 --> 03:22.470 We can simply type those commands and update the operating system. 03:23.230 --> 03:26.320 And these are really important to run periodically. 03:26.560 --> 03:28.750 So those are some basic commands for Linux. 03:28.750 --> 03:35.200 Again, as we go through the course and we start using other commands like um, um, GitHub downloading 03:35.200 --> 03:40.450 for GitHub and whatnot and running specific Python commands while I walk you through that also. 03:40.450 --> 03:43.600 But these are the very basics that you're going to want to learn. 03:43.600 --> 03:44.860 Thank you for watching. 03:44.860 --> 03:45.940 I'll see you next video.
