SharePoint 2013 App Deployment PowerShell

In SharePoint 2013 App Development and Deployment we come across situations to automate the Upload and Install of SharePoint 2013 App to Corporate Catalog. Please find below the PowerShell to automate that process.

#-----Function to Load SharePoint PowerShell Environment----#
function LoadSharePointPowerShellEnvironment
{
    write-host "Setting up PowerShell environment for SharePoint..." -foregroundcolor Yellow
    Add-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue
    write-host "SharePoint PowerShell Snapin loaded." -foregroundcolor Green
}
#-----Function to create output log file--#
function CreateLogFile {
param($logFileName)
 New-Item $logFileName -type File
 Set-Content $logFileName "Starting App Upload and Deployment......"
}
function Main($inputAppCatalogSiteCollectionUrl, $inputFolderLocation, $inputSiteCollectionUrl)

Download a WSP Solution From SharePoint

I had a requirement where I need to download the deployed WSP from central admin,but CA doesn't provide link to download that. After investigating I found a solution using PowerShell. So sharing that may be you can benefit of that.

$farm = Get-SPFarm

$file = $farm.Solutions.Item("corporate.build.wsp").SolutionFile
$file.SaveAs("d:\corporate.build.wsp")

Thanks
