Quick reminder for tomorrow"™s session from the UK PowerShell group. Details from: http://msmvps.com/blogs/richardsiddaway/archive/2013/01/16/uk-powershell-group-29-january-2013.aspx
A question came up about piping between advanced functions. The input to the second function might be an array. To illustrate how this works imagine a function that gets disk information ““ or better still use this one. `function get-mydisk { [ CmdletBinding ( ) ] param ( [string] $computername = “$env:COMPUTERNAME” ) BEGIN { } #begin PROCESS { Get-WmiObject -Class Win32_LogicalDisk -ComputerName $computername | foreach { New-Object -TypeName PSObject
My test environment usually has a dozen or so machines at any one time. Some of these are short lived and used for a particular piece of testing ““ others are kept for years. I decided that I wanted to keep up to date on the patching of these virtual machines so installed WSUS on a Windows 2012 box. One issue is that if a VM isn"™t started for 10 days WSUS starts complaining that it hasn"™t been contacted and if you run the WSUS clean up wizard the non-reporting servers may be removed.
Ok the embarrassing moral of this story is that you shouldn’t answer questions in a hurry at the end of the evening. 5 minutes after shutting down I realised that there is a far, far simpler way to get the info. Win32_AccountSID is a WMI linking class. It links Win32_SystemAccount and Win32_SID classes. Get-WmiObject -Class Win32_SystemAccount | select Caption, Domain, Name, SID, LocalAccount gets you all you need
I realised there is an easier way to get the data `function get-SID { param ( [string] $computername = $env:COMPUTERNAME ) Get-WmiObject -Class Win32_AccountSID -ComputerName $computername | foreach { $exp = “[wmi]'” $( $_ . Element ) “'” Invoke-Expression -Command $exp | select Domain , Name , SID , LocalAccount } } `Use the wmi type accelerator with the path from the Element and you can just select the data you want.
A question asked about passing a function name into another function which then called the function. It sounds worse than it is. if you need to pass the name of a command and then call it try using invoke-expression `function ffour { Get-Random } function fthree { Get-Date } function ftwo { param ( [string] $fname ) Invoke-Expression $fname } “date” ftwo fthree “random” ftwo ffour `
A question on the forum asked about finding the accounts and SIDs on the local machine. `function get-SID { param ( [string] $computername = $env:COMPUTERNAME ) Get-WmiObject -Class Win32_AccountSID -ComputerName $computername | foreach { $da = ( ( $_ . Element ) . Split ( “.” ) [ 1 ] ) . Split ( “,” ) $sid = ( $_ . Setting -split “=” ) [ 1 ] -replace ‘"’
