Preface

If you use PowerShell modules, it is important that you always have the latest version on your local hard drive. This way, you can ensure that you are always using the latest features and bug fixes. In this article, I will show you how to ensure that you always have the latest version of your PowerShell modules on your local hard drive.

Step 1: Check your PowerShell version

Before you start, make sure you are using PowerShell version 7.x or higher. If you are using an older version of PowerShell, update it to the latest version.

Step 2: Write PowerShell script

Here is the PowerShell script that goes through your local modules and ensures that only the current version is present on the hard drive. Old versions are deleted. The script is suitable for PowerShell version 7.x.

$modules = Get-Module -ListAvailable
foreach ($module in $modules) {
    $moduleName = $module.Name
    $moduleVersion = $module.Version
    $modulePath = $module.Path
    $latestVersion = (Find-Module $moduleName).Version
    if ($moduleVersion -ne $latestVersion) {
        Write-Host "Deleting old version of module $moduleName"
        Remove-Module $moduleName
        Remove-Item $modulePath
        Install-Module $moduleName -Force
    }
}

The script goes through all the modules available on your system and compares the version of each module with the latest version available on the PowerShell repository. If an old version is found, it is deleted and the latest version is installed.

Step 3: Run PowerShell script

Save the script in a file with the extension .ps1. Open PowerShell and navigate to the location of the file. Run the script by entering the file name.

.\script.ps1

Summary

Writing PowerShell scripts can be an effective way to ensure that you always have the latest version of your modules on your local hard drive. The script I presented in this article goes through all the modules available on your system and compares the version of each module with the latest version available on the PowerShell repository. If an old version is found, it is deleted and the latest version is installed.

One advantage of this script is that it ensures that you are always using the latest version of your modules. One disadvantage is that it may take some time to go through all the modules on your system.
