Скачать или смотреть PowerShell - Foreach-Object

(A practical example on foreach-object in powershell)
In this video I demonstrate a valid reason for using foreach-object instead of foreach

Sometimes foreach-object can be handy although its slow it has some point of value if you want to instantly interact with the output for instance

*foreach-object
*when to to use foreach-object
*when to use foreach
*when to use for


Code:

param (
[Parameter(Mandatory=$false)]$Computers = @("dsc10","dsc11","dsc13","dsc14","dsc15","dsc16"),
[Parameter(Mandatory=$false)]$filetofind = "A*.dll"
)

$CWD = Split-Path -parent $MyInvocation.MyCommand.Definition #Current Dir of script

try {
$domainpass = Unprotect-CmsMessage -Path "$CWD\domainpass.txt" | ConvertTo-SecureString -AsPlainText -Force
$domainuser = "home\mark"
$domainCreds = New-Object -Typename System.Management.Automation.PSCredential -ArgumentList $domainuser, $domainpass
}
catch {
Write-ToLog -Message "Error during credential decryption $($_.exception.message)" -Category ERROR
exit -1
}

$Computers | ForEach-Object {
$computername = $_
#Test-Connection $computername -count 1
Invoke-Command -ComputerName $computername -ScriptBlock {
$result = Get-ChildItem "C:\Windows\system32"-Filter $using:filetofind |
select name, fullname, VersionInfo
foreach ($item in $result){
$props = [ordered]@{
filename = $item.Name
fullname = $item.fullname
fileversion = $item.VersionInfo.fileversion
computername = $ENV:COMPUTERNAME
}
New-Object psobject -Property $props
}
} -Credential $domainCreds
