1 00:00:01,040 --> 00:00:03,330 PowerShell is a brilliant automation and 2 00:00:03,330 --> 00:00:06,080 configuration management framework. But 3 00:00:06,080 --> 00:00:07,430 did you know there's a lot more to 4 00:00:07,430 --> 00:00:10,010 PowerShell than what comes by default out 5 00:00:10,010 --> 00:00:13,440 of the box? There's an entire ecosystem of 6 00:00:13,440 --> 00:00:15,350 commands and functions that have been 7 00:00:15,350 --> 00:00:17,600 written by individuals and companies to 8 00:00:17,600 --> 00:00:19,810 enhance the usability of PowerShell, 9 00:00:19,810 --> 00:00:22,220 enabling integration and management of 10 00:00:22,220 --> 00:00:25,780 many other platforms and applications. Hi, 11 00:00:25,780 --> 00:00:27,780 my name is Matt Allford, and I'm excited 12 00:00:27,780 --> 00:00:29,770 to have you here with me on this course, 13 00:00:29,770 --> 00:00:32,380 Extending PowerShell. We're going to focus 14 00:00:32,380 --> 00:00:35,170 on working with PowerShell modules. As 15 00:00:35,170 --> 00:00:37,110 noted in the course overview, I am 16 00:00:37,110 --> 00:00:38,490 assuming you've been working with the 17 00:00:38,490 --> 00:00:40,670 PowerShell console already and are 18 00:00:40,670 --> 00:00:42,650 familiar with tasks such as running 19 00:00:42,650 --> 00:00:45,180 commands, piping commands, PowerShell 20 00:00:45,180 --> 00:00:47,620 parameters, and, in general, the 21 00:00:47,620 --> 00:00:51,050 PowerShell language. For the scenario in 22 00:00:51,050 --> 00:00:53,530 this course, I'd like to introduce you to 23 00:00:53,530 --> 00:00:55,860 Jill Anderson, who is a desktop support 24 00:00:55,860 --> 00:00:58,840 engineer for a company named Globomantics. 25 00:00:58,840 --> 00:01:01,190 Globomantics still has a number of manual 26 00:01:01,190 --> 00:01:03,960 IT processes in place, but Jill has been 27 00:01:03,960 --> 00:01:06,510 skilling up on PowerShell with a goal to 28 00:01:06,510 --> 00:01:09,040 automate and optimize tasks and processes, 29 00:01:09,040 --> 00:01:11,570 and in doing so, showing value back to the 30 00:01:11,570 --> 00:01:13,780 business. Through learnings from her 31 00:01:13,780 --> 00:01:16,190 favorite online training platform, Jill 32 00:01:16,190 --> 00:01:18,470 does have a fundamental understanding of 33 00:01:18,470 --> 00:01:20,380 the PowerShell language and how to run 34 00:01:20,380 --> 00:01:22,770 commands, filter results, and work with 35 00:01:22,770 --> 00:01:25,990 data. But up to this point, she's been 36 00:01:25,990 --> 00:01:27,570 working with commands that ship with the 37 00:01:27,570 --> 00:01:30,240 operating system by default and would now 38 00:01:30,240 --> 00:01:32,600 like to extend the usability of PowerShell 39 00:01:32,600 --> 00:01:35,140 by using commands she's seen in articles 40 00:01:35,140 --> 00:01:38,090 and guides online. Jill noticed these 41 00:01:38,090 --> 00:01:40,050 commands aren't installed on her computer, 42 00:01:40,050 --> 00:01:42,640 and she isn't really sure where to start. 43 00:01:42,640 --> 00:01:44,700 Throughout this course, we'll help Jill 44 00:01:44,700 --> 00:01:47,490 understand how authors of PowerShell code 45 00:01:47,490 --> 00:01:49,910 publish their code and how she can find 46 00:01:49,910 --> 00:01:52,360 and consume PowerShell modules to enhance 47 00:01:52,360 --> 00:01:54,670 and extend her PowerShell experience, 48 00:01:54,670 --> 00:01:57,400 making PowerShell even more powerful. 49 00:01:57,400 --> 00:01:59,230 Throughout this course, we're going to 50 00:01:59,230 --> 00:02:02,050 cover a range of topics. First up is 51 00:02:02,050 --> 00:02:04,400 introducing PowerShell modules. We'll 52 00:02:04,400 --> 00:02:06,760 cover what a PowerShell module is and 53 00:02:06,760 --> 00:02:09,220 discuss why creators of PowerShell content 54 00:02:09,220 --> 00:02:10,770 typically package their commands in 55 00:02:10,770 --> 00:02:13,290 modules. We'll get hands on with some of 56 00:02:13,290 --> 00:02:15,260 the modules that are preinstalled on an 57 00:02:15,260 --> 00:02:17,680 out‑of‑the‑box Windows 10 machine, and 58 00:02:17,680 --> 00:02:19,750 you'll learn how to import a module while 59 00:02:19,750 --> 00:02:22,110 also understanding that PowerShell can 60 00:02:22,110 --> 00:02:24,020 auto‑load modules under certain 61 00:02:24,020 --> 00:02:27,220 circumstances. To wrap up, I'll show you 62 00:02:27,220 --> 00:02:28,900 how to identify which commands are 63 00:02:28,900 --> 00:02:31,390 available inside of a module, and that's 64 00:02:31,390 --> 00:02:33,260 going to be critical because the commands 65 00:02:33,260 --> 00:02:35,110 are the object that you'll be working with 66 00:02:35,110 --> 00:02:38,540 most frequently in the PowerShell console. 67 00:02:38,540 --> 00:02:40,890 In a later module, Managing PowerShell 68 00:02:40,890 --> 00:02:42,820 Modules, you'll understand and work with 69 00:02:42,820 --> 00:02:45,630 package management and repositories, and 70 00:02:45,630 --> 00:02:47,780 then we'll spend some time in the console 71 00:02:47,780 --> 00:02:50,320 going through demos to ensure you know how 72 00:02:50,320 --> 00:02:53,050 to find, install, update, and manage 73 00:02:53,050 --> 00:02:55,680 modules. I'll introduce that module a bit 74 00:02:55,680 --> 00:02:57,710 more in depth in the first clip of that 75 00:02:57,710 --> 00:02:59,980 module. I just wanted to give you a primer 76 00:02:59,980 --> 00:03:02,130 here about some of the topics that we'll 77 00:03:02,130 --> 00:03:05,500 end up covering. Now, one last thing 78 00:03:05,500 --> 00:03:07,870 before we get stuck in. This course is 79 00:03:07,870 --> 00:03:10,420 constructed in a way to be hands on, and 80 00:03:10,420 --> 00:03:12,670 I'd love for you to follow along with me, 81 00:03:12,670 --> 00:03:15,540 as that will absolutely help solidify the 82 00:03:15,540 --> 00:03:17,700 concepts and techniques that I'm going to 83 00:03:17,700 --> 00:03:20,660 be teaching you. I'm a huge believer in 84 00:03:20,660 --> 00:03:22,420 hands on for learning concepts, 85 00:03:22,420 --> 00:03:25,020 techniques, and tools. I want to spend a 86 00:03:25,020 --> 00:03:27,040 moment to show you my environment, as 87 00:03:27,040 --> 00:03:29,740 we'll be spending a lot of time here. I've 88 00:03:29,740 --> 00:03:32,470 got a Windows 10 desktop and I've followed 89 00:03:32,470 --> 00:03:35,250 the Installing PowerShell section of Jeff 90 00:03:35,250 --> 00:03:37,480 Hicks' Installing and Running PowerShell 91 00:03:37,480 --> 00:03:39,260 course, and that got me PowerShell 7 92 00:03:39,260 --> 00:03:43,010 installed. If I run Get‑ComputerInfo and 93 00:03:43,010 --> 00:03:44,990 then select the windowsproduct name and 94 00:03:44,990 --> 00:03:46,740 the Windows version, we'll see that I'm 95 00:03:46,740 --> 00:03:49,170 running Windows 10 Pro at version 2004. 96 00:03:49,170 --> 00:03:52,310 But do note that you don't particularly 97 00:03:52,310 --> 00:03:54,600 need to be on this build of Windows 10 to 98 00:03:54,600 --> 00:03:56,400 follow along. As long as you've got 99 00:03:56,400 --> 00:03:59,480 PowerShall 7, that's the main thing. If I 100 00:03:59,480 --> 00:04:02,810 then run $PSVersionTable, you can see here 101 00:04:02,810 --> 00:04:05,130 that I'm running version 7 of PowerShell, 102 00:04:05,130 --> 00:04:07,760 but with that said, pretty much everything 103 00:04:07,760 --> 00:04:10,110 in this course is applicable all the way 104 00:04:10,110 --> 00:04:13,760 back to PowerShell version 3. Also, one 105 00:04:13,760 --> 00:04:15,770 other thing to point out. For the duration 106 00:04:15,770 --> 00:04:17,890 of this course, I'll be running PowerShell 107 00:04:17,890 --> 00:04:20,750 with elevated privileges. This is required 108 00:04:20,750 --> 00:04:22,810 when working with modules, especially when 109 00:04:22,810 --> 00:04:24,720 we get to installing and uninstalling 110 00:04:24,720 --> 00:04:26,370 modules. So I'm just going to run it 111 00:04:26,370 --> 00:04:28,870 elevated by default, and if I'm not 112 00:04:28,870 --> 00:04:30,500 running it elevated for a particular 113 00:04:30,500 --> 00:04:34,000 reason, I'll make sure to call that out to you.
