Modules in PowerShell

 Modules in PowerShell

Modules are used to organize and distribute PowerShell code. They allow you to bundle together scripts, functions, and other resources into a single package that can be easily shared and reused. Here's an example:

# Create a new module manifest

New-ModuleManifest -Path "MyModule\MyModule.psd1" `

    -Author "John Doe" `

    -Description "My PowerShell module" `

    -RootModule "MyModule.psm1" `

    -Version "1.0.0"

# Create a new module script

New-Item -Path "MyModule\MyModule.psm1" `

    -ItemType File `

    -Value @"

function Get-HelloWorld {

    Write-Host "Hello, World!"

}

"@

# Import the module

Import-Module -Name "MyModule"

# Call a function from the module

Get-HelloWorld

In this example, we create a new PowerShell module called MyModule. We use the New-ModuleManifest cmdlet to create a manifest file that describes the module, and the New-Item cmdlet to create a module script that defines a function called Get-HelloWorld. We then use the Import-Module cmdlet to import the module into our session, and call the Get-HelloWorld function.
