1 00:00:06,960 --> 00:00:08,710 So let's do a brief review. 2 00:00:08,760 --> 00:00:13,950 We've seen some helpful Linux terminal commands and helpful Windows command line commands that will 3 00:00:13,950 --> 00:00:17,740 allow us to do some pretty impressive things from the command line. 4 00:00:18,120 --> 00:00:23,310 We started with the basics, like listing the directory contents and changing directories. 5 00:00:23,580 --> 00:00:26,090 Remember, we can change directories up with dot dot. 6 00:00:26,100 --> 00:00:32,220 We can change to the root of the file system with a slash, we can change to our user directory, just 7 00:00:32,220 --> 00:00:33,450 CD and then enter. 8 00:00:34,110 --> 00:00:39,420 We could see some information like the hostname and then the operating system information. 9 00:00:40,170 --> 00:00:41,880 We've seen how to do our history. 10 00:00:41,880 --> 00:00:43,550 We can also use that up arrow. 11 00:00:43,860 --> 00:00:50,210 And remember, we can always use the tab key to autocomplete, the name of a directory or a file. 12 00:00:50,910 --> 00:00:53,640 We used Echo to print something to the screen. 13 00:00:53,650 --> 00:01:01,230 We also saw how to use Echo with a greater than symbol or the right angle there to redirect output to 14 00:01:01,230 --> 00:01:01,730 a file. 15 00:01:02,130 --> 00:01:10,800 We saw how to use Nano, the text editor in our Linux environment, and then we did a control o to write 16 00:01:10,800 --> 00:01:12,930 the output and control X to exit. 17 00:01:13,950 --> 00:01:16,920 We saw how to use the pseudo or super user do command. 18 00:01:17,610 --> 00:01:25,110 We saw how to more the contents of a file we could make and remove directories with make dear and dear, 19 00:01:25,590 --> 00:01:33,240 we can copy, move and remove, copy, copy, move and are in the and remove R.M.. 20 00:01:33,900 --> 00:01:40,890 We saw how we could even find and locate files, find by name or locate and we saw we do that update 21 00:01:40,890 --> 00:01:45,480 DB Command so that we updated that indexed database of all the files on the system. 22 00:01:45,960 --> 00:01:52,900 We saw how to use a couple of advanced commands like ping and interface, config if config for our networking 23 00:01:52,900 --> 00:01:55,170 can check to see if we get a connection out to the Internet. 24 00:01:55,410 --> 00:01:59,070 And the same thing with our interface config, we can see what our IP address is. 25 00:01:59,730 --> 00:02:06,300 By default, we get a ten to 15 on our nat'l just because of the default setup and virtual box, but 26 00:02:06,300 --> 00:02:11,880 we'll see how to make that a more useful and more secure network in the next section. 27 00:02:12,240 --> 00:02:19,290 We saw how we can do the man command or the manual command or use a dash dash help after any command 28 00:02:19,290 --> 00:02:19,920 in Linux. 29 00:02:20,220 --> 00:02:25,230 To get more information about all of the options for that command, we could print our working directory 30 00:02:25,230 --> 00:02:32,310 with TWD and we could show all our environment variables with the EMV or the Environment Command in 31 00:02:32,310 --> 00:02:32,940 Windows. 32 00:02:32,940 --> 00:02:36,000 Most of those had an exact equivalent or something really close. 33 00:02:36,300 --> 00:02:42,930 Remember, the Diaa command gave us the directory so L's and Linux, Dyax and Windows, KDDI worked 34 00:02:42,930 --> 00:02:43,710 very similarly. 35 00:02:43,710 --> 00:02:48,270 We could change directories and we can change up by doing KDDI space dot dot. 36 00:02:48,540 --> 00:02:54,930 We can change to the route with CD space slash and then CD showed our current working directory. 37 00:02:55,230 --> 00:02:57,660 Remember, we have to use one of those environment variables. 38 00:02:57,660 --> 00:03:04,650 If we want to change into our home directory, we can use user profile or home path surrounded by parentheses 39 00:03:05,430 --> 00:03:12,750 percent symbols with the CD command, V.R. gave us our OS info and hostname told us our hostname. 40 00:03:12,750 --> 00:03:17,970 If you want that dos ke slash h dasuki space slash h. 41 00:03:18,300 --> 00:03:20,190 It's an old command to give us our history. 42 00:03:20,340 --> 00:03:24,360 We can also use the up arrow to go back and forth, up and down. 43 00:03:24,480 --> 00:03:26,880 Among our history of commands and the command line. 44 00:03:27,210 --> 00:03:33,840 We saw how to echo something to the screen, same as in Linux Echo with the right angle bracket to echo 45 00:03:33,960 --> 00:03:35,850 to redirect it out to a file. 46 00:03:36,180 --> 00:03:41,430 We can even run notepad from the command line and windows and notepads face in the name of a file. 47 00:03:41,430 --> 00:03:43,680 Let us create a new text document. 48 00:03:44,040 --> 00:03:47,910 We can more just like we can back in Linux to show the contents of the file. 49 00:03:48,240 --> 00:03:50,580 We can make directories and remove directories. 50 00:03:50,580 --> 00:03:57,540 With McDeere in room, dear, we can also use a shortened version and Windows MBD and then we can copy, 51 00:03:57,540 --> 00:03:59,220 move and delete files. 52 00:03:59,220 --> 00:04:06,870 Those we have to spell out, copy, spell out, move and then DTL for delete a file instead of CPM. 53 00:04:06,870 --> 00:04:14,730 The NRM, both the ping and IP config commands work exactly like they did in Linux, except we use IP 54 00:04:14,730 --> 00:04:21,180 config instead of RF config in Windows, then Khedive will help us print the current directory. 55 00:04:21,390 --> 00:04:26,730 We can use the HELP command instead of the manual command help and then the name of the command that 56 00:04:26,730 --> 00:04:27,780 we want to get help on. 57 00:04:27,780 --> 00:04:34,950 Or we give that command name space slash questionmark and that gives us the contents of that command. 58 00:04:35,160 --> 00:04:39,540 And then finally, if we want to see all the environment variables on our machine set, we'll do it 59 00:04:39,540 --> 00:04:41,130 for us and a Windows environment. 60 00:04:41,490 --> 00:04:47,250 So we've seen both the Linux and the Windows commands to do some pretty helpful things from the command 61 00:04:47,250 --> 00:04:49,050 prompt in the next lesson. 62 00:04:49,050 --> 00:04:55,920 In the next section, we're going to see how to set up our virtual environment lab networks so that 63 00:04:55,920 --> 00:04:59,130 we can do something safely inside a host only network. 64 00:04:59,370 --> 00:05:03,600 And then some things where we need to connect to the outside world on the World Wide Web. 65 00:05:04,110 --> 00:05:06,060 So I'll see you in the next section.
