PowerShell Cheat Sheet Compilation (Part 2)

In the previous tip we pointed you to a great compilation of PowerShell cheat sheets. Let’s now check out how easily PowerShell can download these sheets for you:

# enable SSL download
$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
[System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols

# download page
$url = "https://github.com/PrateekKumarSingh/CheatSheets/tree/master/Powershell"
$page = Invoke-WebRequest -UseBasicParsing -Uri $url
$links = $page.Links | 
    Where-Object { $_.href -like '*.pdf' } |
    Select-Object -Property title, href |
    # turn URLs into directly downloadable absolute URLs
    ForEach-Object {
        $_.href = 'https://github.com/PrateekKumarSingh/CheatSheets/raw/master/Powershell/' + $_.title
        $_
    }

# create folder on your desktop
$Path = "$home\Desktop\CheatSheets"
$exists = Test-Path -Path $Path
if (!$exists) { $null = New-Item -Path $path -ItemType Directory }

# download cheat sheets
$links | ForEach-Object {
    $docPath = Join-Path -Path $Path -ChildPath $_.Title
    Start-BitsTransfer -Source $_.href -Destination $docPath -Description $_.title
    # alternate way of downloading
    # Invoke-WebRequest -UseBasicParsing -Uri $_.href -OutFile $docPath
}

# open folder
explorer $Path

When you run this script, PowerShell downloads all cheat sheets and places them into a new folder called “CheatSheets” on your desktop. Happy reading!
