foreach ($computer in $computerlist) { if((Test-Connection -Cn $computer -BufferSize 16 -Count 1 -ea 0 -quiet)) { foreach ($file in $REMOVE) { Remove-Item "\\$computer\$DESTINATION\$file" -Recurse Copy-Item E:\Code\powershell\shortcuts\* "\\$computer\$DESTINATION\" } } else { Write-Host "\\$computer\$DESTINATION\" } } I want to export Write-Host "\$computer\$DESTINATION\" to the CSV files so I know which computers were offline when the script ran. I am running this from a Windows 7 machine This solution creates a psobject and adds each object to an array, it then creates the csv by piping the

I was able to find how to use the GetInvalidFileNameChars() method in a PowerShell script. However, it seems to also filter out whitespace (which is what I DON'T want). EDIT: Maybe I'm not asking this clearly enough. I want the below function to INCLUDE the spaces that already existing in filenames. Currently, the script filters out spaces. Function Remove-InvalidFileNameChars { param([Parameter(Mandatory=$true, Position=0, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [String]$Name ) return [RegEx]::Replace($Name, "[{0}]" -f ([RegEx]::Escape([String][System.IO.Path]:

I have the following powershell script $list = invoke-sqlcmd 'exec getOneMillionRows' -Server... $list | % { GetData $_ > $_.txt ZipTheFile $_.txt $_.txt.zip ... } How to run the script block ( { GetDatta $_ > $_.txt ....} ) in parallel with limited maximum number of job, e.g. at most 8 files can be generated at one time? Start-Automating The Start-Job cmdlet allows you to run code in the background. To do what you'd ask, something like the code below should work. foreach ($server in $servers) { $running = @(Get-Job | Where-Object { $_.State -eq 'Running' }) if ($running.Count -le 8) { Start

I want to write a PowerShell script that will recursively search a directory, but exclude specified files (for example, *.log , and myFile.txt ), and also exclude specified directories, and their contents (for example, myDir and all files and folders below myDir ). I have been working with the Get-ChildItem CmdLet, and the Where-Object CmdLet, but I cannot seem to get this exact behavior. The Get-ChildItem cmdlet has an -Exclude parameter that is tempting to use but it doesn't work for filtering out entire directories from what I can tell. Try something like this: function GetFiles($path =

I am trying to have PowerShell unblock a file in Win2K8 R2. Does anyone have a pointer as to the syntax? Joey If you are using PowerShell v3, you can use the Unblock-File cmdlet. The "blocking" part is simply an alternate data stream of the file, named "Zone.Identifier". You can display it in CMD by using input redirection (no other way to get to a stream in CMD, though): H:\Downloads> more < test.exe:Zone.Identifier [ZoneTransfer] ZoneId=3 You can find them using dir /r on Windows Vista and later: 2009-10-24 12:18 54.538.056 test.exe 24 test.exe:Zone.Identifier:$DATA Also in CMD you can
