    <description><![CDATA[<p>Working in large enterprise environments often means managing a complex landscape of repositories across multiple GitHub organizations and Azure DevOps projects. Keeping these repositories up to date—especially when working with multiple engineering teams—can be a daunting task. That’s where automation comes in.</p>
<p>To simplify this, I’ve developed a consolidated PowerShell script that combines the functionality of my previous scripts into one:</p>
<ul>
<li><a href="https://github.com/segraef/Scripts/blob/main/PowerShell/Update-Repos.ps1" target="_blank" rel="noopener noreffer">Update-Repos.ps1</a></li>
</ul>
<p>This script helps automate the process of cloning and updating repositories, making it significantly easier to manage a large number of repos efficiently.</p>]]></description>
