1
00:00:06,410 --> 00:00:12,600
Previously we have learned how to update the value of description used in power show.

2
00:00:12,620 --> 00:00:18,040
Now let's take a look at update and telephone numbers of multiple users.

3
00:00:18,050 --> 00:00:24,040
This operation is a little different from updating the description operation here.

4
00:00:24,150 --> 00:00:27,790
They have two complexities which are as follows.

5
00:00:27,890 --> 00:00:35,420
The first one we don't know which attribute will get updated when a number is added to the telephone

6
00:00:35,420 --> 00:00:39,420
number failed in the graphical user interface.

7
00:00:39,500 --> 00:00:48,260
And the second complexity is performing a telephone number update for multiple users by reading from

8
00:00:48,260 --> 00:00:51,540
a text file or CSP file.

9
00:00:51,560 --> 00:00:56,210
First we need to identify attributes that need to be updated.

10
00:00:56,210 --> 00:01:04,640
So when we want to update the office telephone number home number and mobile number of the users if

11
00:01:04,640 --> 00:01:14,510
this user is already have this number set then we can use that attribute editor to identify the attribute

12
00:01:14,510 --> 00:01:17,090
names that need to be updated.

13
00:01:17,090 --> 00:01:26,450
If not then we need to set these telephone numbers for one user account and then use attribute editor

14
00:01:26,720 --> 00:01:29,360
to identify the attribute names.

15
00:01:29,540 --> 00:01:38,570
Alternatively you can use they get this 80 user command led to retrieve all attributes the power shall

16
00:01:38,570 --> 00:01:43,640
we say is preferred here as we want to learn more and more about it.

17
00:01:43,730 --> 00:01:51,110
Let's examine the output of the following command carefully and identify the attribute names that have

18
00:01:51,110 --> 00:01:55,670
the telephone numbers you see in the graphical user interface.

19
00:01:55,790 --> 00:02:02,450
So first let's run this command get there say the user identity.

20
00:02:02,510 --> 00:02:03,240
TOM call.

21
00:02:03,260 --> 00:02:09,110
CARL So my aunt will be looking for all the properties of this object.

22
00:02:09,110 --> 00:02:16,160
You'll notice that the following command has a telephone number as you see in the graphical user interface

23
00:02:16,370 --> 00:02:21,830
and it outputs too much information which you don't need right now.

24
00:02:21,830 --> 00:02:26,240
So we could select some properties we need right now.

25
00:02:26,480 --> 00:02:34,750
So let's run this command again with pipe and select home phone office phone and mobile phone.

26
00:02:34,760 --> 00:02:40,250
The description of the precedent command is shown in the forward an office phone.

27
00:02:40,250 --> 00:02:48,140
This attribute contains the phone number that you see on the under the main field and telephone numbers

28
00:02:48,230 --> 00:02:56,350
in Active Directory administrative center an Active Directory user some computer you'll see this number

29
00:02:56,370 --> 00:03:01,190
in the telephone number field in the general term home phone.

30
00:03:01,190 --> 00:03:06,650
This is a phone number you will see in the home phone field and mobile.

31
00:03:06,680 --> 00:03:11,440
This attribute contains the phone number you will see in the mobile field.

32
00:03:11,540 --> 00:03:15,370
First let's update the telephone details so one year.

33
00:03:15,680 --> 00:03:26,000
Then we can extend the logic to did other users in bulk let's store the numbers in variables first let's

34
00:03:26,000 --> 00:03:31,730
create three variables for office number home number and mobile number.

35
00:03:31,730 --> 00:03:39,350
The first variable will contain sorry will be named dollar character office number and will be equal

36
00:03:39,350 --> 00:03:41,180
to the number we need.

37
00:03:41,270 --> 00:03:44,890
Then we'll have home number and mobile number wearables.

38
00:03:44,900 --> 00:03:51,800
The next step is to update the preceding values for a user account as shown in this command set.

39
00:03:51,830 --> 00:04:00,290
There say the user is the following properties identity office phone which will get the variable of

40
00:04:00,410 --> 00:04:04,250
office number home form mobile form.

41
00:04:04,250 --> 00:04:11,870
This is a straight forward because the set the shady user command led has parameters that can set these

42
00:04:11,870 --> 00:04:13,100
phone numbers.

43
00:04:13,100 --> 00:04:20,690
If the attribute that you are trying to set is not available as a parameter to the command led then

44
00:04:20,690 --> 00:04:29,420
you can use the dash add parameter to directly specify the attribute name and the value.

45
00:04:29,690 --> 00:04:40,040
Similarly you can use as a parameter such as this replace and dash clear parameter to your Chris attributes

46
00:04:40,040 --> 00:04:46,490
directly the precedent example can be rewritten using the dash add parameter.

47
00:04:46,490 --> 00:04:49,710
So let's review this command set.

48
00:04:49,720 --> 00:04:57,050
There's a user again with identity parameter and clear parameter.

49
00:04:57,140 --> 00:05:06,270
So we'll be clear telephone number home phone and mobile and again will run the following command said

50
00:05:06,360 --> 00:05:16,110
a user identity and at the following parameters so telephone number will be equal to offers no variable

51
00:05:16,320 --> 00:05:22,070
home phone to home number and mobile to mobile number variable.

52
00:05:22,080 --> 00:05:29,600
Now we can extend this logic to multiple users using a for loop in power shell.

53
00:05:29,700 --> 00:05:38,790
Before doing this store the user names and numbers of want to set in a ceasefire file and imported into

54
00:05:38,790 --> 00:05:48,120
power shall so I have the following ancestry file let me open it and show you the values of this file

55
00:05:48,450 --> 00:05:56,880
and the code to set the telephone numbers will look like that will add a variable and other variable

56
00:05:57,180 --> 00:06:06,000
users which will be equal equal to the following command import CEV command led and the file in which

57
00:06:06,000 --> 00:06:15,060
you have all the telephone numbers which you want to add to your users then for each user in this file

58
00:06:15,360 --> 00:06:24,660
which is equal to users wearable will add the following code will you set this a d command led with

59
00:06:24,810 --> 00:06:33,780
identity property which will be equal to user with user name property office phone will be equal to

60
00:06:34,080 --> 00:06:42,810
office number variable which we have said before and the same goes for home phone and mobile phone.

61
00:06:42,810 --> 00:06:53,310
Now let's check one of those users let's say John Doe in users and computers console and see if his

62
00:06:53,310 --> 00:06:56,370
phone number is the one we need.

63
00:06:56,430 --> 00:07:05,130
That's open users and computers console right click on the domain and search for the name John and in

64
00:07:05,130 --> 00:07:07,690
his properties in general.

65
00:07:07,980 --> 00:07:16,290
We can find the phone number we can do the same year in active directory administrative center again

66
00:07:16,320 --> 00:07:25,290
we click right click on the domain and search for the name John and here we have all three numbers which

67
00:07:25,290 --> 00:07:27,330
we've modified before.

68
00:07:27,360 --> 00:07:36,270
Also if you scroll down to the bottom you could find this attribute all the attributes which could be

69
00:07:36,270 --> 00:07:39,990
used to modify this object.

70
00:07:40,110 --> 00:07:41,420
This user object.
