The Copy-Item Container parameter controls whether the folder structure is also copied. Lets start with the source material – a folder C:\test with a bunch of files. A destination folder C:\D1 also exists PS> Copy-Item -Path c:\test\* -Destination C:\D1 copies the files from test to D1 PS> Copy-Item -Path c:\test -Destination C:\D1 copies the […]
Recently saw a question asking why this code worked PS> $a = ‘aa’ PS> $b = ‘a’ PS> $a -like “*$b*” True PS> Remove-Variable -Name b PS> $a -like “*$b*” True Set 2 variables and compare using wildcards. The comparison comes back as True as you’d expect. Remove $b and try the comparison again. […]

PowerShell has the Split-Path cmdlet that provides the leaf and parent of a path. But what if you’re splitting paths and need one or paths at a higher level. Consider the path PS> $path = ‘C:\Scripts\HyperV\Admin\Optimize-VMDisks.ps1’ Its just an arbitrary path from my test machine. Using Split-Path you can get the parent (by default) […]

On the surface Get-Date is a simple cmdlet that’s been around since PowerShell v1. However, it has some interesting quirks. In this post I’ll show how Get-Date –DisplayHint works. By default Get-Date returns the data and time PS> Get-Date 13 September 2018 16:09:34 The DisplayHint parameter ( available in PowerShell v5.1, 6.0 and 6.1) modifies […]
