1
00:00:06,210 --> 00:00:12,350
You need to learn the basics and have a point of reference for build on your own scripts.

2
00:00:12,430 --> 00:00:19,810
And this lesson will cover core power shell concepts that will provide you with a foundation of knowledge

3
00:00:19,900 --> 00:00:23,470
for using their remaining examples.

4
00:00:23,500 --> 00:00:31,570
In this course if you are already familiar with power shell you may want to use this video as a review

5
00:00:31,600 --> 00:00:36,780
or as a reference for later after you've started writing scripts.

6
00:00:36,790 --> 00:00:41,830
If you are completely new to power shell the concept might be familiar.

7
00:00:41,830 --> 00:00:51,190
If you've worked with Unix common shells like Unix based shells or Shell also allows you to stream multiple

8
00:00:51,190 --> 00:00:56,230
commands together on one line using a technique called Pipeline.

9
00:00:56,230 --> 00:01:01,790
This means that the output of one command becomes the input for another.

10
00:01:01,810 --> 00:01:07,790
First off let's open power shall run a search for power shall on your computer.

11
00:01:07,840 --> 00:01:15,830
You probably have several different options like power shall power shall I as a power shell x eighty

12
00:01:15,870 --> 00:01:16,950
six.

13
00:01:17,010 --> 00:01:24,400
The ISC or integrated scripting environment as I have mentioned already is a handy tool which allows

14
00:01:24,400 --> 00:01:31,730
you to write scripts on the fly and also has a conventional low carb for all the power shell commands.

15
00:01:31,750 --> 00:01:38,860
Right now this is more than we need access to six exist for backwards compatibility.

16
00:01:38,860 --> 00:01:47,690
We want X 64 bit for our usage and we'll use the one just called Windows power show.

17
00:01:47,740 --> 00:01:55,450
You may want to be in it to your bar right click it together this option when you open it it will look

18
00:01:55,450 --> 00:01:56,170
like this.

19
00:01:56,350 --> 00:02:04,930
If you don't like the white on blue right click the top bar select properties and go to colors to change

20
00:02:04,930 --> 00:02:05,770
things.

21
00:02:05,770 --> 00:02:12,250
You may have to close and threw open power shell together to display correctly when we are ready.

22
00:02:12,250 --> 00:02:20,620
We can navigate our system and I seen about power shall as you always know where you are because it

23
00:02:20,620 --> 00:02:22,860
tells you that in the prompt.

24
00:02:22,960 --> 00:02:27,500
In my case it's like this but you should see something similar.

25
00:02:27,550 --> 00:02:35,240
Marta is your user name in case you don't just type a cell space field character.

26
00:02:35,350 --> 00:02:37,210
Make sure to include this space.

27
00:02:37,210 --> 00:02:39,130
This will bring you to your home.

28
00:02:39,130 --> 00:02:48,640
Director a director is just another word for folder and power shell considers your user folder to be

29
00:02:48,640 --> 00:02:49,740
your home.

30
00:02:49,860 --> 00:02:58,960
Entering our cell space tilt is just like opening the folder called to users and from there using your

31
00:02:58,960 --> 00:03:00,790
graphical user interface.

32
00:03:00,910 --> 00:03:07,420
So let's start by learning how to move around between directories and view their contents.

33
00:03:07,420 --> 00:03:13,810
To view director accountants you could use get the child item command led.

34
00:03:13,840 --> 00:03:16,470
There are several aliases for it.

35
00:03:16,470 --> 00:03:28,360
Also you could type GC I alas or Dear All those are aliases for the get this child Titan command let

36
00:03:28,540 --> 00:03:35,860
our first command is girl child Titan so go ahead and type it in and hit enter.

37
00:03:35,860 --> 00:03:39,530
You'll see a list of everything in your current director.

38
00:03:39,670 --> 00:03:45,010
In my case that looks like this it could be different on your screen.

39
00:03:45,010 --> 00:03:52,710
Notice that instead of this long command get this child to item you could just enter juicy AI.

40
00:03:52,840 --> 00:03:57,850
It's an abbreviation for it or alias the commands will let command.

41
00:03:57,850 --> 00:04:02,750
So we will be alone in are all of the form verb Dash.

42
00:04:02,770 --> 00:04:11,080
Now these so-called command levels and to their form is supposed to make it easy to remember what they

43
00:04:11,080 --> 00:04:16,670
do and predict similar command levels because command lets a rather long.

44
00:04:16,720 --> 00:04:20,170
Most of them come with slick or aliases.

45
00:04:20,170 --> 00:04:23,610
As I've mentioned that you can use instead.

46
00:04:23,710 --> 00:04:24,970
I will first present.

47
00:04:24,970 --> 00:04:32,770
Come on let's with their names but all this subsequently use the standard aliases because they are much

48
00:04:32,770 --> 00:04:34,530
faster to work with.

49
00:04:34,540 --> 00:04:40,920
It is important to note that many command LEDs have multiple aliases for instance.

50
00:04:41,050 --> 00:04:49,920
These Goodchild type item either GCI dear or less all of them do exactly the same thing.

51
00:04:49,990 --> 00:04:59,440
While it is unsurprising that GCI is short forget child Titan you might be wondering where deer or alas

52
00:04:59,440 --> 00:05:05,690
come from power show is relatively new and its designer as anticipated.

53
00:05:05,800 --> 00:05:13,420
Many people who would use it would already have experience with some existing command line interface

54
00:05:13,510 --> 00:05:20,950
specifically either with Microsoft command line interface called command prompt or as Linux command

55
00:05:20,950 --> 00:05:27,660
line interface like bash which is now also standard on all six last man.

56
00:05:27,670 --> 00:05:35,320
Come on let's have an alias that is standard command in one of these two systems and often for both

57
00:05:35,530 --> 00:05:44,020
in the present example duel comes from command prompt and allows comes from bash I'll use power shell

58
00:05:44,020 --> 00:05:52,660
style aliases in this demonstration but I'll try to mention are the common aliases particular those

59
00:05:52,660 --> 00:06:02,380
familiar for bash users so Linux users so go ahead and try use them GCI dear or allows command and see

60
00:06:02,380 --> 00:06:04,600
the contents of your directory.

61
00:06:04,600 --> 00:06:13,240
Now when we did it we can move between directories with set dash location command left or as L abbreviation

62
00:06:13,240 --> 00:06:22,570
for it or C D command it's good for common to prompt previous command prompt Windows system and Linux

63
00:06:22,570 --> 00:06:32,170
system lets type a cell and some folder which you can see in the output of your previous command and

64
00:06:32,290 --> 00:06:41,830
it'll change your location from your current location to the folder you've specified we can move back

65
00:06:41,830 --> 00:06:51,430
to your previous location again by type in SL and two dots and of course the space between a cell command

66
00:06:51,460 --> 00:06:59,920
and two dots now trial navigate and back to the folder you've been before and to some other folder Mixon

67
00:07:00,020 --> 00:07:07,870
Siddiqa amount and a cell command if you want to navigate to level sloppier good try type in a cell

68
00:07:08,050 --> 00:07:17,290
space two dots backslash two dots instead of backslash you could also type slash so power Shell is not

69
00:07:17,290 --> 00:07:25,620
case insert sensitive and doesn't care about the slashes so it could be a backslash or just slash.

70
00:07:25,640 --> 00:07:34,390
Now we can try create a new directorate with M card dear command in any folder you lie if you want to

71
00:07:34,390 --> 00:07:42,490
get back to your home direct to reforest you could type again a cell space tilt and it'll get you to

72
00:07:42,490 --> 00:07:51,250
your home director and here we can make a new directory Let's type M Kadir and call the directory like

73
00:07:51,400 --> 00:08:01,030
the s or whatever name your line Move into your new director using as our command by type in a cell

74
00:08:01,060 --> 00:08:09,670
and whatever your title to your director in my case it's appears now Let's type GC I and you'll see

75
00:08:09,670 --> 00:08:16,120
that there is nothing here that's because we've just created this directory and it's empty we could

76
00:08:16,240 --> 00:08:25,120
again create a sub directory here with M.K. dear so let's create it type in M.K. dear and give it some

77
00:08:25,120 --> 00:08:34,090
long name in quotes like this is very long name note that if you give some long name to this directory

78
00:08:34,090 --> 00:08:36,190
you should put it in quotes.

79
00:08:36,260 --> 00:08:43,290
Now enter GCI and hit enter again and you'll see your new directory.

80
00:08:43,300 --> 00:08:51,550
Suppose we want to move into this director who would have to type as L and this long name.

81
00:08:51,550 --> 00:09:00,310
Not only will this take a while to tie but if we have got one letter from power shall won't be able

82
00:09:00,310 --> 00:09:01,900
to find our director.

83
00:09:02,230 --> 00:09:03,340
Instead try.

84
00:09:03,580 --> 00:09:12,430
Just type in a cell D and then hit the tab key and power shall complete the name of the director for

85
00:09:12,430 --> 00:09:20,590
you including the quotes you then tap for auto completion will save you a lot of time you'll notice

86
00:09:20,590 --> 00:09:29,240
that when power shell completed the name it also threw in a dot backslash at the beginning of the directory

87
00:09:29,250 --> 00:09:36,790
name the dot is just shorthand for the car and director when you type commands power shall.

88
00:09:36,790 --> 00:09:41,530
All this assumes there is a dot backslash at the beginning.

89
00:09:41,560 --> 00:09:48,490
In other words that you are referring to Sampson in the current director so you don't have to type this

90
00:09:48,490 --> 00:09:50,650
part all the time.

91
00:09:57,670 --> 00:10:04,780
If you want to find some specific command but don't know if this command exists at all you could use

92
00:10:05,080 --> 00:10:13,390
get command command led which is very important and you can try looking for a command with this command

93
00:10:13,400 --> 00:10:22,450
lat so get command itself will output all the commands which are available for you if you need some

94
00:10:22,450 --> 00:10:31,540
command which will be looking for a noun like process you could use get command the noun and specify

95
00:10:31,540 --> 00:10:39,430
the noun you're looking for for example process if you are looking for a command which contains a verb

96
00:10:39,730 --> 00:10:48,250
like start stop etc. You could try years and get command this verb and specify the warp you are looking

97
00:10:48,250 --> 00:10:56,440
for for example start if you're looking for some specific command which is part of some module which

98
00:10:56,440 --> 00:11:04,660
you know like power shall get or active directory module or some other module you could try using get

99
00:11:04,660 --> 00:11:13,080
command module power shall get that will find all the commands in that specific module and of course

100
00:11:13,080 --> 00:11:20,170
you could the standard with specified that you are looking for verb in that module like get commander's

101
00:11:20,170 --> 00:11:27,550
module power shall get and you are looking for a verb find in that module of course you can always look

102
00:11:27,550 --> 00:11:36,910
for help on that command with Get the hell command let and specify the command you need help on for

103
00:11:36,910 --> 00:11:47,410
example find this module get help have has several options like get help us on line get help desk fool

104
00:11:47,690 --> 00:11:56,730
etc. You could try type and get help find this module this fool or dash online or dash.

105
00:11:56,770 --> 00:12:03,130
Examples that will show you only the examples of usage of this command

106
00:12:10,530 --> 00:12:18,750
in addition to get an command led help for commands you can use get help to view supplemental help files

107
00:12:19,080 --> 00:12:27,270
that explain General Power shell concepts that focus primarily on script and to display the help file

108
00:12:27,270 --> 00:12:29,970
for a particular concept type.

109
00:12:29,970 --> 00:12:38,700
Get help about underscore followed by the concept name for example to view the help for the core power

110
00:12:38,700 --> 00:12:39,530
shell commands.

111
00:12:39,530 --> 00:12:40,830
Type the following.

112
00:12:40,830 --> 00:12:50,570
Get help about underscore core underscore commands or to view the entire list of conceptual help files

113
00:12:50,940 --> 00:12:52,610
using the following command.

114
00:12:52,740 --> 00:12:56,430
Get help about underscore asterisk.

115
00:12:56,460 --> 00:13:05,160
Now some words about command aliases throughout this course and the examples used will refer to command

116
00:13:05,160 --> 00:13:07,850
tell us or command letter aliases.

117
00:13:07,920 --> 00:13:16,470
For example the short name of the full command let the aliases can be very handy when trying to type

118
00:13:16,730 --> 00:13:24,290
long scripts where you might want to optimize and keep them as small as and as short as possible.

119
00:13:24,300 --> 00:13:27,990
For instance we have the command left where object.

120
00:13:27,990 --> 00:13:30,220
We have two aliases for it.

121
00:13:30,300 --> 00:13:36,120
You can use question mark for it or just wear it.

122
00:13:36,120 --> 00:13:39,290
Another example is for a rich object.

123
00:13:39,300 --> 00:13:42,300
There are two aliases for riot as well.

124
00:13:42,390 --> 00:13:48,690
You can use % character or just one word for reach.

125
00:13:48,690 --> 00:13:50,850
Another example is select object.

126
00:13:50,970 --> 00:13:59,720
You can use alias just select for release command lat and so on to get a list of all car until this

127
00:13:59,730 --> 00:14:00,910
is just type.

128
00:14:00,920 --> 00:14:02,420
Get Alice.

129
00:14:02,450 --> 00:14:04,950
Now some words about pipelines.

130
00:14:04,980 --> 00:14:12,530
The single most important concept in power Shell is the use of its flexible object based pipeline.

131
00:14:12,660 --> 00:14:15,580
The concept of pipelines is similar.

132
00:14:15,660 --> 00:14:20,450
Is that your sound and the output from one command to another.

133
00:14:20,550 --> 00:14:27,600
But instead of passing plaintext power shell works with objects and we can accomplish some very complex

134
00:14:27,600 --> 00:14:30,540
tasks in just a single line of code.

135
00:14:30,690 --> 00:14:39,210
As a quick example you can get all the services running on the server and pipe it to stop servers command

136
00:14:39,210 --> 00:14:41,340
let with just one line.

137
00:14:41,340 --> 00:14:45,360
You will find all the services and stop them of course.

138
00:14:45,360 --> 00:14:49,390
Don't try to perform this on production server.

139
00:14:49,410 --> 00:14:55,500
Now let's take a look at using a variable sound to objects which you'll be using very often.

140
00:14:55,500 --> 00:15:03,660
The variables are supposed to save temporal data to a new object so you can workers at later for example

141
00:15:03,660 --> 00:15:09,470
to create a variable that stores an instance of the test user mail books.

142
00:15:09,510 --> 00:15:17,420
You can type the following command do your character mailbox equals to get mail box test user.

143
00:15:17,580 --> 00:15:24,600
As you can see to create a variable or instance of an object you prefix the variable name with a dollar

144
00:15:24,600 --> 00:15:27,530
assigned to the right of the variable name.

145
00:15:27,600 --> 00:15:36,510
You have to use the equals assignment operator followed by the value of or the object that should be

146
00:15:36,510 --> 00:15:38,480
assigned to the variable.

147
00:15:38,490 --> 00:15:45,660
Keep in mind that the variables are only available during your current shell session and will be destroyed

148
00:15:45,690 --> 00:15:47,610
when you close the shell.

149
00:15:47,610 --> 00:15:56,060
And remember that you can work with variables in the same room as you work with any object containing

150
00:15:56,330 --> 00:15:59,090
its properties methods and so on.
