To connect to the specific azure subscription using Az CLI we need to use “Az account set” command but before using this command make sure you are connected with the Azure cloud using “az login” account.az account set --subscription 'subscription name or id'You can also use -s instead of --subscription.az account set -s 'subscription name or id'To check if the subscription is set properly, use the below command.PS C:\> az account show -otable
To login to the Azure account using Azure CLI, we need to use the az login command. Once you type the az login command, it will prompt for the Azure portal login console.If you need to log in with the device authentication code in the browser, you need to use the parameter –use-device-code.PS C:\> az login --use-device-code To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code ‘DeviceCode’ to authenticate.You need to open a website https://microsoft.com/devicelogin/ and have to enter a code. If you are not already connected with the Microsoft Azure portal, you ... Read More
To get the Application security groups of the Azure VM using PowerShell, we need to first get the Network Interface of the Azure VM.The below command will retrieve the NIC name of the Azure VM.PS C:\> $vm = Get-AzVM -Name TestVM $nic = (($vm.NetworkProfile.NetworkInterfaces.id).Split('/'))[-1]Once we have the NIC name, we can use the Get-AzNetworkInterface command to retrieve the NIC information and the Security group.The below command will retrieve the application security group names using PowerShell.PS C:\> $nicsettings = Get-AzNetworkInterface -Name $nic $nicsettings.IpConfigurations.ApplicationSecurityGroups
To get all the subnets attached to the virtual network using PowerShell, we need to use the GetAzVirtualNetwork command.PS C:\> $vn = Get-AzVirtualNetwork -Name VirtualNetworkNameTo get the Subnets and its address prefix details, you need to filter out the Subnets and AddressPrefixPS C:\> $vn.Subnets | Select Name, AddressPrefix
To get all the files that are modified after certain days, we need to use the LastWriteTime property.The below command shows us the files which are modified within the last 30 days in the C:\temp folder.Get-ChildItem C:\Temp | where{$_.LastWriteTime -ge (GetDate).AddDays(-30)}You can also use the AddMonths() or AddYears() instead of AddDays() as per your requirement.To get all the files that are modified before 30 days, use the below command.Get-ChildItem C:\Temp | where{$_.LastWriteTime -le (GetDate).AddDays(-30)}To get the file modified after a specific date, you need to compare the LastWriteTime with the Date. For example, we need all the files that are ... Read More
Power or Electric PowerThe rate at which work is done in an electric circuit is called as electric power. In other word, the work done per unit time is termed as electric power. It is denoted p or P.Formula and Unit of PowerWhen voltage is applied across a resistor, it causes current to flow through it. Therefore, work is being done in moving the electrons through the resistor in a unit time is called the electric power.Referring the above figure, $$\mathrm{V=\frac{work}{Q}}$$$$\mathrm{\Rightarrow work(W)=VQ=VIt}$$As, the power is defined as work done per unit time i.e.$$\mathrm{Power(P)=\frac{work\:done\:in\:electric\:circuit(W)}{Time(t)}=\frac{VIt}{t}}$$$$\mathrm{(∵V=IR\:or\:I=\frac{V}{R})}$$$$\mathrm{∴P=VI=I^2R=\frac{V^2}{R}}$$The above three formulae are equally valid for ...
