In case you don’t get the SAPIEN Newsletter, here’s my PowerShell one-liner for the month.<\/p>\n
The Get-Command<\/strong> cmdlet can return information not only about cmdlets but other applications and scripts that PowerShell “knows” about. This month I have a PowerShell one-liner that uses Get-Command<\/strong> to find all PowerShell scripts in any folder in your path. Using a series of Select-Object<\/strong> expressions, the one-liner displays the script name, location, its size, when it was created, when it was last modified and the status of its digital signature (using Get-AuthenticodeSiganture<\/strong>. You do sign your production scripts don’t you? I’m sorting the output by folder and size but you may have other uses for this information. This is technically a one-line expression but I’ve split it up for legibility.<\/p>\n Here’s a sample of what you can expect:<\/p>\n Name : Initialize-VIToolkitEnvironment.ps1 Name : voicedemo.ps1 To take this further I would turn this into a function or scriptblock to make it easy to reuse.<\/p>\nGet-Command -commandtype externalscript | <\/pre>\n
select Name,@{name=\"Folder\"<\/span>;expression={<\/pre>\nSplit-Path $_.definition -parent}},@{<\/pre>\nname=\"Size\"<\/span>;Expression={<\/pre>\n(Get-ChildItem $_.definition).length}},@{<\/pre>\nname=\"Created\"<\/span>;Expression={<\/pre>\n(get-childitem $_.definition).CreationTime}},@{<\/pre>\nname=\"Modified\"<\/span>;Expression={<\/pre>\n(get-childitem $_.definition).LastWriteTime}},@{<\/pre>\nname=\"Signature\"<\/span>;Expression={<\/pre>\n(Get-AuthenticodeSignature $_.definition).Status }} |<\/pre>\n
