1 00:00:01,140 --> 00:00:05,940 Next, let's take a look at selecting objects and parts of objects. 2 00:00:05,940 --> 00:00:10,190 Once again, Get‑Vegetable, just to reinforce the concepts, 3 00:00:10,190 --> 00:00:12,110 and pipe to Select‑Object. 4 00:00:12,110 --> 00:00:13,060 And you know what? 5 00:00:13,060 --> 00:00:15,510 I just want to see the first three vegetable objects. 6 00:00:15,510 --> 00:00:19,040 I just need a little sample. There we go. 7 00:00:19,040 --> 00:00:24,940 Select‑Object, in this situation, writes the vegetable object onto the pipeline, 8 00:00:24,940 --> 00:00:29,140 but only shows me the first three. 9 00:00:29,140 --> 00:00:32,050 We can also use Select‑Object to select properties. 10 00:00:32,050 --> 00:00:37,850 So I'm going to pipe Get‑Vegetable to a Select‑Object and specify the Count, 11 00:00:37,850 --> 00:00:42,840 Name, and State properties that I see listed there. 12 00:00:42,840 --> 00:00:45,040 Except I don't see a state. 13 00:00:45,040 --> 00:00:45,700 What happened? 14 00:00:45,700 --> 00:00:46,040 Well, 15 00:00:46,040 --> 00:00:48,140 this is something very similar to what we had just 16 00:00:48,140 --> 00:00:51,540 looked at in the last example here. 17 00:00:51,540 --> 00:00:54,550 And here's a good way to demonstrate how you can use 18 00:00:54,550 --> 00:00:58,380 Select‑Object to discover property names, 19 00:00:58,380 --> 00:00:59,740 as well as using Get‑Member. 20 00:00:59,740 --> 00:01:03,340 Sometimes Select‑Object is a little bit easier, and I'll show you why. 21 00:01:03,340 --> 00:01:06,040 So I'm going to select just the first one, 22 00:01:06,040 --> 00:01:08,120 and I'm going to combine parameters because you can 23 00:01:08,120 --> 00:01:09,280 do that here with Select‑Object. 24 00:01:09,280 --> 00:01:10,620 I'm going to tell PowerShell, 25 00:01:10,620 --> 00:01:15,060 get me the first vegetable object and select all properties, 26 00:01:15,060 --> 00:01:18,740 and you can use the wildcard there. 27 00:01:18,740 --> 00:01:19,440 There we go. 28 00:01:19,440 --> 00:01:22,950 So this is kind of like Get‑Member. I see all the property names, 29 00:01:22,950 --> 00:01:25,840 but I also see the values. 30 00:01:25,840 --> 00:01:29,130 When you just do Get‑Member, and if you look at properties, 31 00:01:29,130 --> 00:01:30,370 all you see are names. 32 00:01:30,370 --> 00:01:33,880 And sometimes it's hard to tell, okay, I see that name there, 33 00:01:33,880 --> 00:01:36,440 but what does that really mean? 34 00:01:36,440 --> 00:01:40,540 Well, when you see the property name and the value, 35 00:01:40,540 --> 00:01:44,820 often it makes it much easier to line up what it is that you're looking for. 36 00:01:44,820 --> 00:01:46,220 And in this situation, 37 00:01:46,220 --> 00:01:50,060 now I can tell that I want the CookedState. That's the 38 00:01:50,060 --> 00:01:52,440 property name that I want to use. 39 00:01:52,440 --> 00:01:57,240 So let's do Get‑Vegetable, pipe it to Select‑Object again, 40 00:01:57,240 --> 00:02:01,580 this time I'm just using the positional parameter values of Count, 41 00:02:01,580 --> 00:02:06,270 Name, and CookedState, and now I get the results that I am expecting. 42 00:02:06,270 --> 00:02:09,870 That Select‑Object trick, select a representative object, 43 00:02:09,870 --> 00:02:11,180 select all properties, 44 00:02:11,180 --> 00:02:14,640 it's a great way to discover the property names and the 45 00:02:14,640 --> 00:02:19,640 values that you might want to be working with. 46 00:02:19,640 --> 00:02:22,840 All right, let's try this now with some regular commands. 47 00:02:22,840 --> 00:02:28,240 Let's do get‑service and select the Name and StartType. 48 00:02:28,240 --> 00:02:30,540 Sure enough, that works pretty nicely. 49 00:02:30,540 --> 00:02:33,780 Let's try a new command, kind of getting tired of Get‑Service. 50 00:02:33,780 --> 00:02:35,740 Let's do get‑winevent. 51 00:02:35,740 --> 00:02:41,540 And I want to list the System event log on my computer. 52 00:02:41,540 --> 00:02:45,160 Now I'm not listing the entries, I'm just listing the log itself, 53 00:02:45,160 --> 00:02:50,540 so I can see some nice information there about the event log file. 54 00:02:50,540 --> 00:02:51,960 But maybe there's more to this. 55 00:02:51,960 --> 00:02:57,170 So let's use my little trick here, and let's list the System event log, 56 00:02:57,170 --> 00:03:01,840 pipe to Select‑Object, and look at all properties. 57 00:03:01,840 --> 00:03:02,270 There we go. 58 00:03:02,270 --> 00:03:06,740 So I can look at that, and I can see what properties I might want to work with. 59 00:03:06,740 --> 00:03:07,730 Let's try this then. 60 00:03:07,730 --> 00:03:09,440 Let's do get‑winevent. 61 00:03:09,440 --> 00:03:11,440 In this case, now that I know the properties, 62 00:03:11,440 --> 00:03:16,940 I'm going to do this for all the event logs that are listed on my system. 63 00:03:16,940 --> 00:03:20,600 I'm going to select the Logname, the Recordcount, 64 00:03:20,600 --> 00:03:25,640 the MaximumSizeInBytes, and the FileSize. 65 00:03:25,640 --> 00:03:27,730 And just to make this, again, a little bit different, 66 00:03:27,730 --> 00:03:31,140 I'm going to send this to a new cmdlet called Out‑GridView. 67 00:03:31,140 --> 00:03:35,190 This will display the results, let me bring this up here, 68 00:03:35,190 --> 00:03:39,580 in a screen that is a graphical window. 69 00:03:39,580 --> 00:03:43,140 And you can click on the column headings to sort, 70 00:03:43,140 --> 00:03:45,690 you can do additional filtering. There's really no way to 71 00:03:45,690 --> 00:03:49,520 zoom in or to make this any bigger, but there you have it. 72 00:03:49,520 --> 00:04:01,000 I can take the results, select the properties that I want, in this case, what I just listed there, and then I sent it to Out‑GridView.
