WEBVTT 00:00.960 --> 00:07.900 And this lesson will continue with certain selecting and finding different objects for your own it's 00:08.710 --> 00:18.600 all at church and europaeus drive for our purposes to refer to this place try and get some child items 00:18.600 --> 00:21.870 from this folder. 00:22.050 --> 00:27.110 So I'll share it with the name and it will be. 00:27.290 --> 00:37.360 Pierce provider file system and the root of it all will find some folders a lot of files for our testing 00:37.380 --> 00:48.810 purposes so let's find a know dotnet folder and there are a lot of lots of files there and we can manipulate 00:49.200 --> 00:55.050 them and do some different kinds of operations. 00:55.080 --> 01:03.530 So the root of this is Dr. Phil big windows rentals Dot Net framework and so on. 01:03.600 --> 01:07.160 This is for real be our work in folders. 01:07.260 --> 01:12.780 So now let's get to that do it a bit larger. 01:12.950 --> 01:25.670 Let's get child tired old for this newly created Pia's drive for you referred to as by by its name term. 01:26.680 --> 01:40.360 CONAN And let's make a pie get mamber to see what we can do with this with this object. 01:40.510 --> 01:48.790 So as you can see we have different properties some mindsets which could be used on these objects. 01:48.790 --> 02:00.280 Let's let's sort by member type and get on the properties to see what we can do not not do so to see 02:00.280 --> 02:02.540 what scribe's this object. 02:02.560 --> 02:12.790 So there are several properties like land's name full name extension cetera so we can work with its 02:12.790 --> 02:19.860 properties and sort of select the files. 02:20.740 --> 02:26.590 Regarding its properties Let's get child item pipe. 02:26.590 --> 02:35.050 After that who will perform this the next command select object and we want to select object by its 02:35.050 --> 02:36.280 property. 02:36.650 --> 02:48.880 Let's say full name and lands and maybe after that as you can see we get all the full names of the files 02:48.880 --> 03:00.610 from this Pia's drive from this folder and if we want to get an extension we can type Acoma extension 03:00.610 --> 03:11.050 and then we will get an extension of the files which are located in this folder and if we wanted to 03:11.050 --> 03:22.350 have some more properties like Klan's we can add that after coma and space as you can see a lot of a 03:22.360 --> 03:30.550 lot of faction's could be done if you know the property of the file and where to get this property you 03:30.550 --> 03:36.580 can get files specific files which you need. 03:36.700 --> 03:45.490 Now if you want to have some new property you can create it by yourself and you created with the help 03:45.490 --> 03:57.300 of the sign then you open this break its name and that stands for name name will really be equal to 03:57.540 --> 04:02.230 to the name of the colon or of the property you want to create. 04:02.230 --> 04:06.640 I'll give it a name like the size in kilobytes. 04:06.670 --> 04:18.880 Say you want to to to view the property lands in kilobytes So let's create a new property for these 04:18.880 --> 04:29.390 files and it will be named sites and kilobytes and on it it should be done like this. 04:29.390 --> 04:35.930 So you give it a glance and and divide it by 24. 04:36.070 --> 04:47.650 So there's a dollar sign and underscored Daut means that you're if you're the object with which comes 04:48.370 --> 04:56.060 from the pipe which was before so it refers to each object of this pipe. 04:56.320 --> 05:05.590 And if you want to refer to the subject to you you type it like this as you can see we have another 05:05.590 --> 05:11.690 column here which is exactly what we wanted to see. 05:11.690 --> 05:16.920 We wanted to see lengths in kilobytes and we get it. 05:17.560 --> 05:31.080 Let's let me show you another another way of typing this referring to each each object of the piper. 05:31.120 --> 05:32.890 You can type it like this. 05:33.030 --> 05:39.830 You your type dollar sign and item you can select. 05:40.000 --> 05:41.620 You can pick up. 05:41.740 --> 05:55.760 And in my set of type in reference to each item each each object of the pie dollar sign underscore or 05:56.060 --> 05:57.280 dollar sign. 05:57.380 --> 06:00.380 Item. 06:01.010 --> 06:05.080 Let's continue and go even further. 06:05.150 --> 06:05.690 Let me 06:08.500 --> 06:13.320 admins let me sort this. 06:14.130 --> 06:24.060 This results by property name so you can sort by any properties you remember if you want to sort by 06:24.570 --> 06:32.220 extension or Lanz or any other property which this object possesses. 06:32.220 --> 06:42.600 You can sort of like the size in kilobytes you can sort by your new property which you've already just 06:42.600 --> 06:54.550 created and that proves that if you if you create it it has all the qualities of a real object that 06:54.630 --> 07:01.180 you can search by property and you can manipulate it like real objects. 07:01.260 --> 07:11.080 And so let's go even further on that select object and we'll select first 15 items in this long list. 07:11.950 --> 07:24.040 As you can see with it we can see we can find any number we want in first place. 07:24.070 --> 07:33.280 First 15 items last 15 items if you want to see the tail of the results it will give you the tail of 07:33.280 --> 07:34.160 the results. 07:34.240 --> 07:47.500 You can you can also skip some items if you say want to make some man pager or a pager like system for 07:47.500 --> 07:57.630 example in first in first line of your skip first 15 item then you skip and so first 59. 07:57.660 --> 08:00.080 And then you skip first 15 item so. 08:00.150 --> 08:07.930 So to say it will have a pager like system you can skip and then show fills 15. 08:07.930 --> 08:16.250 So if you want to skip just you just type skip 15 items. 08:16.400 --> 08:18.430 Let's move on and let's 08:21.010 --> 08:22.110 let's. 08:22.380 --> 08:31.910 Let me introduce a new comment to their object where object refers to some properties of the object. 08:31.920 --> 08:42.390 For example you want to find two to find all the objects which are greater than 15 kilobytes or you 08:42.390 --> 08:47.500 want to find all the objects Rylance which is. 08:47.880 --> 08:50.520 Which equals 15 kilobytes. 08:50.520 --> 09:02.940 A lot of operations here as you can see and to the most popular are greater than value equals longer 09:02.980 --> 09:05.900 them etc.. 09:06.120 --> 09:19.910 So let's find all the objects which are greater than one 10000 kilobytes or whatever you want. 09:20.410 --> 09:33.400 Let's add another zero and we'll get another list of all of this operation. 09:33.510 --> 09:43.820 Let me copy it and you can you can use this vair object by and a property of the object of this set 09:43.920 --> 09:56.060 you can find extensions which are equal to dot Dia lel or dot X or any extension which you want to find. 09:56.060 --> 10:00.910 Right now it's very handy. 10:03.180 --> 10:09.840 Operation you can find whatever you need right now. 10:09.840 --> 10:19.710 Now let's get let's type another command get process and get for example get fields get mamber to see 10:20.490 --> 10:26.480 what properties and methods do we have for that process. 10:28.370 --> 10:30.560 And let's get member for 10:33.560 --> 10:34.070 Paul 10:40.860 --> 10:45.850 Propertius will give us an A. 10:46.290 --> 10:50.340 It was incorrectly. 10:50.410 --> 10:55.960 So let me let me check it and retype it. 10:56.060 --> 10:58.110 Select object to a 11:00.760 --> 11:01.550 property. 11:01.660 --> 11:05.640 Yes that's right again. 11:05.820 --> 11:06.450 Sorry. 11:06.660 --> 11:13.230 Sorry for the child retype it because it wasn't correctly. 11:13.260 --> 11:22.520 So we have to select to get member by its member type property not Massad but property. 11:22.600 --> 11:26.520 We have to see what properties do we have. 11:26.560 --> 11:37.500 Forget ProBusiness and let's say we want to select all the processes and it's virtual memory size which 11:37.500 --> 11:41.490 Prose's consumes how much memory. 11:41.490 --> 11:53.140 So we type got process where where object then does property 11:58.630 --> 12:02.880 and I'll have to compare this property name. 12:02.910 --> 12:06.700 It's quite a long name virtual memory size. 12:11.090 --> 12:23.270 And it should be greater than let's say 2 million or 20 million bytes as you can see we can sort 12:26.180 --> 12:33.760 our Get process results and to get all the results we need. 12:33.860 --> 12:49.770 We need all the proto processes which are greater which consumes more than 20 million kilobytes. 12:49.790 --> 12:59.960 Let's run another command like a good process and see what prophetesses do we have right now running 12:59.990 --> 13:11.150 on the system and let's say we want to find all the processes which which begins with three letters 13:11.390 --> 13:19.730 or some other letters so we can do this type get protests pipe row object then 13:22.390 --> 13:23.650 it's property. 13:33.180 --> 13:46.070 So where object and to its property the name and it should be like starting with as we. 13:46.180 --> 13:55.720 So you have to type property the name and like Desch like that will give us all the names which starts 13:55.720 --> 14:09.610 with as we letters as you can see we can filter freely filter any results with this command where objects 14:09.620 --> 14:11.410 it's very candid. 14:11.410 --> 14:24.400 You can filter the names starters a and any any results which you need right now. 14:24.420 --> 14:41.310 Now let's get child item for temp folder and to select all the objects which are let's say we want to 14:41.310 --> 14:50.940 select different different objects properties to select different object properties you need to write 14:50.940 --> 14:57.850 them down to type them down in break this figure break it's figurative. 14:57.840 --> 14:58.760 Break. 14:59.040 --> 15:08.910 And here you can give some more complicated request for for your objects like extensions should be like 15:08.910 --> 15:18.140 a PLL and it should be like let's say 15:21.830 --> 15:29.780 it should have a name which starts with some specific letters. 15:29.780 --> 15:30.470 Let's say 15:37.490 --> 15:39.490 let me think about it. 15:40.280 --> 15:48.730 Let's say it starts with a letter right and it should be. 15:48.920 --> 15:55.850 It's L'anse should bear more than some some length which you want to find. 15:56.090 --> 15:59.400 Let's say it should be greater than 16:02.940 --> 16:07.890 10000 kilobytes greater or equal. 16:07.930 --> 16:12.960 This means greater or equal. 16:12.960 --> 16:18.790 So you can find objects with this complicated request. 16:18.910 --> 16:22.470 Sorry I have made a mistake. 16:22.690 --> 16:26.060 If you want you can find true just now. 16:26.200 --> 16:31.860 And here it is to stop it to run in your search. 16:31.870 --> 16:35.710 You can press control control see as usual. 16:35.710 --> 16:38.800 And here is my mistake. 16:38.800 --> 16:41.780 I've missed on the score side. 16:42.700 --> 16:44.030 Let's run it once more. 16:44.050 --> 16:52.810 And as you can see it has found all the results which match my request. 16:52.980 --> 16:58.360 Extension is DL and its name has a. 16:58.500 --> 17:05.760 It starts with a letter and its length is greater than 10000 kilobytes. 17:08.870 --> 17:12.320 And I can show you an other method. 17:12.330 --> 17:21.170 Now another way of typing this command if you type it just where without the object it will be working 17:21.170 --> 17:22.470 just fine as well.
