WEBVTT 00:06.360 --> 00:12.340 You need to learn the basics and have a point of reference for building your own scripts. 00:12.510 --> 00:19.920 And this lesson will cover more powerful concepts that will provide you with a foundation of knowledge 00:19.920 --> 00:21.140 for you. 00:21.150 --> 00:27.890 And there remain examples in this course if you are already familiar with power. 00:28.080 --> 00:35.870 You may want to use this video as a review or as a reference for a later after you've started writing 00:35.880 --> 00:36.810 scripts. 00:36.900 --> 00:41.830 If you are completely in your power show the concept may be familiar. 00:41.940 --> 00:51.330 If you've worked with Unix common shelves like Unix based shells Rocio also allows you to string multiple 00:51.330 --> 00:56.280 commands together on one line using a technique called pipelining. 00:56.340 --> 01:01.920 This means that the output of one command becomes the input for another. 01:01.920 --> 01:07.850 First off let's open Power Shell Rona's search for power shell on your computer. 01:07.950 --> 01:17.370 You probably have several different options like Power Shell Power Shell eyes the Power Shell X 86 the 01:17.460 --> 01:24.870 IAC or integrated scripting environment as I've mentioned already is a handy tool which allows you to 01:24.870 --> 01:31.860 write scripts on the fly and also has a conventional low carb for all the power shell commands. 01:31.860 --> 01:38.960 Right now this is more than when the int x 86 exist for backwards compatibility. 01:39.000 --> 01:47.850 We want x 64 bit for our use for general use one just called Windows power shell. 01:47.850 --> 01:53.810 You may want to pin it to your test bar right click it to give this option. 01:53.910 --> 01:56.450 When you open it it will look like this. 01:56.460 --> 02:05.070 If you don't like the white on blue right click the top bar select Properties and go to colors to change 02:05.070 --> 02:05.880 things. 02:05.880 --> 02:11.260 You may have to close and threw open Power Shell to get it to display correctly. 02:11.400 --> 02:19.260 When we are ready we can navigate to our system and I seen about power Challice you always know where 02:19.260 --> 02:23.040 you are because it tells you that in the prompt. 02:23.070 --> 02:30.690 In my case it's Langley's but you should say something similar but with your username in case you don't 02:30.960 --> 02:35.340 just type as cell space field character. 02:35.460 --> 02:37.310 Make sure to include the space. 02:37.310 --> 02:44.820 This will bring you to your home directory directory is just another word for folder and power shell 02:45.000 --> 02:52.250 considers your user folder to be your home and turn SL space. 02:52.280 --> 03:01.040 Tilt is just like opening a folder called to users and from there using your graphical user interface. 03:01.050 --> 03:08.640 So let's start by learning how to move around between directories and view their contents to view directory 03:08.640 --> 03:09.570 contents. 03:09.600 --> 03:13.970 You could use get the child item command layout. 03:13.980 --> 03:16.560 There are several aliases for it. 03:16.570 --> 03:22.350 Also you could type GC LS or D. 03:22.530 --> 03:32.040 All those are aliases for the get the child title command left our first command is Girl Child Titan 03:32.190 --> 03:35.900 So go ahead and type it to him and he turned to her. 03:35.970 --> 03:39.690 You see a list of everything in your current directory. 03:39.810 --> 03:42.240 In my case that looks like this. 03:42.330 --> 03:45.010 It could be different on your screen. 03:45.130 --> 03:52.740 Notice that instead of this long command to get to this child diatom you could just enter jucy II. 03:52.950 --> 03:59.370 It's an abbreviation for it or ls the command so will the command SOORLEY will belong in. 03:59.400 --> 04:03.570 Are all of the form verb dush now. 04:03.700 --> 04:11.190 These are called command lengths and to their form is supposed to make it easier to remember what they 04:11.190 --> 04:14.410 do and predict similar command last. 04:14.520 --> 04:16.680 Because command lets a rather long. 04:16.830 --> 04:23.840 Most of them come with slicker aliases as I've mentioned that you can use instead. 04:23.840 --> 04:25.080 I know fields present. 04:25.100 --> 04:33.510 C'mon let's me their names but Olva's subsequently use standard aliases because they are much faster 04:33.510 --> 04:34.640 to work with. 04:34.650 --> 04:41.160 It is important to note that many criminals have multiple aliases for instance. 04:41.160 --> 04:50.050 These can get child to item either GC ID or or less all of them do exactly the same theme. 04:50.100 --> 04:59.550 While it is unsurprising that GCI is short for get child Titan you may be wondering where dir or ls 04:59.550 --> 05:08.600 come from voer shell is relatively new and its designers anticipated many people who would use it we 05:08.660 --> 05:13.590 already have experience with some existing command line interface. 05:13.610 --> 05:21.080 Specifically are there is Microsoft command line interface called common prompt or is Linux command 05:21.080 --> 05:29.810 line interface like bash which is now also standard on all six last medicament let's have an alias that 05:29.810 --> 05:33.880 is standard command in one of these two systems. 05:33.950 --> 05:42.280 And often for both in the present example dir comes from command prompt and LS comes from Bash. 05:42.340 --> 05:51.240 I'll use PowerShares style aliases in this demonstration but I'll try to mention all the common Eliseus 05:51.260 --> 05:55.910 particular those familiar for best use so Linux users. 05:55.940 --> 06:04.620 So go ahead and try using GCI dir or ls command and see the contents of your directory. 06:04.730 --> 06:12.450 Now when we do that we can move between directories with set the location Come on left or as well. 06:12.470 --> 06:13.990 Abbreviation for it. 06:14.030 --> 06:16.220 Or C D command. 06:16.250 --> 06:23.560 It's good for Command Prompt previous command prompt Windows system and Linux system. 06:23.570 --> 06:32.460 Let's type our cell and some folder which you can see in the output of your previous command and it 06:32.500 --> 06:40.550 will change your location from your current location to the folder you've specified. 06:40.550 --> 06:48.550 We can move back to our previous location again by type in our cell and two dots. 06:48.620 --> 06:52.630 And of course the space between a cell command and two dots. 06:52.640 --> 06:59.460 Now try and navigate back to the folder you've been before and to some other folder. 06:59.530 --> 07:00.490 Makes sense. 07:00.490 --> 07:08.090 The command and cell command if you want to navigate to like Allsop you could try Taipan as well cell 07:08.180 --> 07:14.930 space two dots backslash two dots instead of backslash you could also type slash. 07:14.960 --> 07:24.470 So power shell is not case sensitive and it doesn't care about the slashes so it could be a backslash 07:24.470 --> 07:25.730 or just slash. 07:25.730 --> 07:33.600 Now we can try create a new directory with Qadeer command in any folder you like. 07:33.710 --> 07:41.710 If you want to get back to your home directory fast you could type again and sell space to build and 07:41.720 --> 07:43.990 it'll get you to your home directory. 07:44.120 --> 07:53.300 And here we can make a new directory that's type M-K dear and call the directory like Pyrus or whatever 07:53.540 --> 07:56.950 name you like move into your new directory. 07:57.020 --> 08:04.960 Use an S L command top by Taipan cell and whatever your title to your directory. 08:04.970 --> 08:06.650 In my case it's best. 08:06.710 --> 08:11.610 Now let's type juicy and you'll see that there is nothing here. 08:11.750 --> 08:15.790 That's because we've just created this directory and it's empty. 08:15.830 --> 08:20.650 We could again create a subdirectory here with M-K dear. 08:20.660 --> 08:22.050 So let's create it. 08:22.070 --> 08:27.930 Type in M-K dir and give it some long name in quotes like. 08:28.160 --> 08:30.290 This is a very long name. 08:30.290 --> 08:36.380 Know that if you give some long name to this directory you should put it in quotes. 08:36.380 --> 08:43.430 Now enter GCI and hit enter again and you'll see your new directory. 08:43.430 --> 08:47.180 Suppose we want to move into this directory. 08:47.210 --> 08:49.870 You'd have to type as well. 08:49.980 --> 08:59.150 And this long name not only will this take a while to type but if we have got one letter wrong Power 08:59.150 --> 09:02.330 Shell won't be able to find our director. 09:02.330 --> 09:12.230 Instead try just type in SL D and then hit the tab key and partial completes the name of the directory 09:12.230 --> 09:19.940 for you including the quotes Yulian step 4 or to completion will save you a lot of time. 09:19.970 --> 09:25.070 You'll notice that when power schelde completed the name it also goes through. 09:25.190 --> 09:33.800 Ian Dalt backslash of the beginning of the directory name that dot is just shorthand for the current 09:33.800 --> 09:36.110 directory when you type commands. 09:36.110 --> 09:36.840 Power Shell. 09:36.860 --> 09:41.690 All of this assumes there is a dot backslash at the beginning. 09:41.690 --> 09:46.630 In other words that you are referring to Samson in the current directory. 09:46.730 --> 09:50.330 So you don't have to type this part all the time 09:57.780 --> 10:04.560 if you want to find some specific command but don't know if this command exists at all or you could 10:04.560 --> 10:09.340 use get command command left which is very important. 10:09.510 --> 10:18.510 And you can try looking for a command to this command left so get command itself will output all the 10:18.510 --> 10:26.160 commands which are available for you if you need some command which will be looking for a noun like 10:26.310 --> 10:33.390 proses you could use get command Desch noun and specify the noun you are looking for. 10:33.480 --> 10:42.840 For example Brosius if you are looking for a command which contains a verb like start stop etc. You 10:42.840 --> 10:50.360 could try and get command to destroy roar and specify the word you are looking for for example star. 10:50.490 --> 10:58.800 If you're looking for South Pacific Command which is part of some module which you know like Power Shell 10:58.800 --> 11:07.320 get or active directory model or some other module you could try use and get this module power shell 11:07.320 --> 11:12.290 get that will find all the commands in that specific module. 11:12.450 --> 11:19.170 And of course your extend standard is specifying that you are looking for vore and that more do like 11:19.220 --> 11:25.760 get commanders more power shell get Andrea looking for vore find in that module. 11:25.860 --> 11:29.610 Of course you can all of us look for help on that command. 11:29.700 --> 11:39.240 Yes get does help come and let and specify the command you'll need help on for example find does Maggio 11:39.510 --> 11:40.670 get health care. 11:40.780 --> 11:48.730 Course several options like get help does online get help this fool etc.. 11:48.870 --> 11:58.470 You could try Taipan get help find us Mondial that's fool or DERSE online or dush examples that will 11:58.470 --> 12:03.470 show you only examples of usage of this command. 12:10.640 --> 12:18.260 In addition to get and come and get help for commands you can use get help to view supplemental help 12:18.260 --> 12:26.630 files that explained General Power Shell concepts that focused primarily on scriptum to display the 12:26.630 --> 12:36.080 help file for a particular concept type get help about underscore followed by the concept name for example 12:36.340 --> 12:39.660 to use the help for the core power shell commands. 12:39.670 --> 12:40.850 Type the following. 12:40.940 --> 12:50.690 Get help about underscore or underscore commands or to view the entire list of conceptual help files 12:51.020 --> 12:56.510 using the form and come and get help about underscore asterisk. 12:56.570 --> 13:05.270 Now some words about command aliases through all discourse and the examples used when refer to a command 13:05.300 --> 13:08.010 trellises or common Gletty aliases. 13:08.060 --> 13:17.180 For example the short name of the fool command let the LSS can be very handy when trying to type long 13:17.180 --> 13:24.430 scripts where you might want to optimize and keep them as small as and as short as possible. 13:24.440 --> 13:27.970 For instance we have the command let a rare object. 13:28.130 --> 13:30.370 We have two aliases for it. 13:30.410 --> 13:36.230 You can use a question mark for it or just wear it. 13:36.230 --> 13:39.410 Another example is for each object. 13:39.410 --> 13:42.440 There are two aliases for it as well. 13:42.500 --> 13:48.800 You can use bosomed character or just one vote for each. 13:48.800 --> 13:50.940 Another example is select objects. 13:51.080 --> 13:59.590 You can use Elyas just select for release command left and so on to get a list of all current. 13:59.600 --> 14:02.360 This is just I've get ls. 14:02.560 --> 14:05.050 Now some words about pipeline's. 14:05.090 --> 14:12.460 The single most important concept in both a shell is the use of its flexible object based by applying 14:12.770 --> 14:15.760 the concept of pipelines that is similar. 14:15.800 --> 14:20.440 Is that your Sandom the output from one command to another. 14:20.660 --> 14:27.710 But instead of parsing plaintext power shell works with objects and we can accomplish some very complex 14:27.710 --> 14:30.700 tasks in just a single line of code. 14:30.800 --> 14:39.310 As a quick example you can get all the services running on the server and pipe it to stop service command 14:39.320 --> 14:44.870 left with just one line and you will find all the services and stop them. 14:44.870 --> 14:49.370 Of course don't try to perform this on production server. 14:49.520 --> 14:55.550 Now let's take a look at using a variable Zantop jokes which you will be using very often. 14:55.610 --> 15:03.800 The variables are supposed to save temporal data to a new object so you can workers it later for example 15:03.800 --> 15:09.560 to create a variable that stores an instance of the test user mailbox. 15:09.620 --> 15:16.310 You can type the following command door character mailbox equals to get mailbox. 15:16.400 --> 15:23.630 Test User as you can see to create a variable or instance of an object you prefix the variable name 15:23.630 --> 15:27.680 with the dollar sign to the right of the variable name. 15:27.710 --> 15:36.650 You have to use that equals assignment operator followed by the ratio of or the object that should be 15:36.650 --> 15:38.630 assigned to the variable. 15:38.630 --> 15:45.800 Keep in mind that the variables are only available during your current shell session and will be destroyed 15:45.800 --> 15:47.630 when you close the shell. 15:47.720 --> 15:56.250 And remember that you can work with variables in the same frame as you work with any object containing 15:56.290 --> 15:57.770 named its properties. 15:57.770 --> 15:59.240 My thoughts are also on.
