Hello,
You’ll find all the new capabilities of PowerShell 5 here.
Hereunder a few things I like :
PSReadLine module (Need Windows 10, or Server 2016)
New-Guid
New-TemporaryFile
Clipboard cmdlets
Format-Hex
Get-ChildItem -Recurse -Depth 2
And the last but not least, “ConvertFrom-String“, a very powerful one if you do not like RegEx.
