I have a string in my psobject and it will only apply for 10 devices but not the 11th one. How do I construct a string and not include one variable if it's the 11th one?
This is what works for the first 10 in my foreach:
$INFO_Tab = New-Object psobject -Property $([ordered]#{
DEVICE = "$($currentDevice)"
Platform = "Name"
Device_Error_Description = "ErrorCodeList files \Retail\Tools\ServiceEndToEnd\ErrorCodeList "
OCP_Display = "sdkDesc in $BaseName $($cppFile)" #$BaseName doesn't apply for $currentDevice="Scanner"
...
})
$xlsx = $INFO_Tab | Export-Excel -Path $outFilePathExcel -WorksheetName "Source" -Autosize -AutoFilter -FreezeTopRow -BoldTopRow -PassThru
Can I do something like this for the OCP_Display line? I can't find an example.
OCP_Display = "sdkDesc in"+ if($currentDevice="Scanner"):"":$BaseName +$($cppFile)"
This is with PowerShell 5.1 and VSCode.
Wrap the if statement in a subexpression $():
"sdkDesc in $(if($currentDevice -ne 'Scanner'){"$BaseName "})$($cppFile)"
It looks like you need $() not just () even outside a string. Aside from that, it helps to know powershell basics.
$currentdevice = 'Unscanner'
$basename = 'Basename'
$cppfile = 'Cppfile'
"Prefix" + $(if($currentDevice -eq "Scanner"){""}else{$BaseName}) + $cppFile
PrefixBasenameCppfile
$currentdevice = 'scanner'
"Prefix" + $(if($currentDevice -eq "Scanner"){""}else{$BaseName}) + $cppFile
PrefixCppfile

I have the following script and it gets me the info I need.
$Monitors = Get-WmiObject WmiMonitorID -Namespace root\wmi
$LogFile = "d:\monitors.csv"
"Manufacturer,Name,Serial" | Out-File $LogFile
ForEach ($Monitor in $Monitors)
{
$Manufacturer = ($Monitor.ManufacturerName|where {$_ -ne 0}|ForEach{[char]$_}) -join ""
$Name = ($Monitor.UserFriendlyName |where {$_ -ne 0}| ForEach{[char]$_}) -join ""
$Serial = ($Monitor.SerialNumberID |where {$_ -ne 0}| ForEach{[char]$_}) -join ""
"$Manufacturer,$Name,$Serial" | Out-File $LogFile -append
}
My problem is the data is exported to the excel spreadsheet like this..
Manufacturer,Name,Serial.
ACI,VE248,K8LMQS048382
HWP,HP P232,6CM8122DXL
HWP,HP P232,6CM7241DRB
I need it to be:
Manufacturer Name Serial
in the spreadsheet, and when I do the next pc, it adds to the next line and so on.
I have looked online and the examples just don't match.
Does anyone have any advice?
As others already commented, use Export-Csv to write out the wanted data in csv format, rather than constructing it manually.
That means your ForEach-Object loop should emit objects instead of lines of concatenated strings.
Also, nowadays, I would use the newer Get-CimInstance instead of Get-WmiObject (What's the difference)
Try
$LogFile = "d:\monitors.csv"
Get-CimInstance -ClassName WmiMonitorID -Namespace root\wmi | ForEach-Object {
[PsCustomObject]#{
Manufacturer = [string]::new($_.ManufacturerName, 0, $_.ManufacturerName.Length).Trim("`0")
Name = [string]::new($_.UserFriendlyName, 0, $_.UserFriendlyName.Length).Trim("`0")
Serial = [string]::new($_.SerialNumberID, 0, $_.SerialNumberID.Length).Trim("`0")
}
} | Export-Csv -Path $LogFile -NoTypeInformation -UseCulture
The -UseCulture switch makes sure the output csv file uses the same delimiter characters your locally installed Excel would expect, so you can simply double-click the file to open it in Excel
I am writing a script that scans each cell in an excel file for PII. I've got most of it working, but I am experiencing two issues which may be related.
First of all, I am not convinced that the "Do" loop is performing as intended. The goal here is if the text in a cell matches the regex string, create a PSCustomObject with the location information, then use the object to add a line to a csv file.
It appears that the loop is running for every file, regardless of whether or not it actually found a match.
The other issue is that I can't seem to actually pull the cell value for the matched cell. I've tried several different variables and methods, the latest attempt being "$target.text," but the value of the variable is always null.
I've been racking my brain on this for days, but I'm sure it'll be obvious once I see it.
Any help here would be appreciated.
Thanks.
$searchtext = "\b(?!0{3}|6{3})([0-6]\d{2}|7([0-6]\d|7[012]))([ -]?)(?!00)\d\d\3(?!0000)\d{4}\b"
$xlsFiles = Get-ChildItem $searchpath -recurse -include *.xlsx, *.xls, *.xlxm | Select-object -Expand FullName
$Excel = New-Object -ComObject Excel.Application
$excel.DisplayAlerts = $false;
$excel.AskToUpdateLinks = $false;
foreach ($xlsfile in $xlsfiles) {
Write-host (Get-Date -f yyyymmdd:hhmm) $xlsfile
try{
$Workbook = $Excel.Workbooks.Open($xlsFile, 0, 0, 5, "password")
}
Catch {
Write-host $xlsfile 'is password protected. Skipping...' -ForegroundColor Yellow
continue
}
ForEach ($Sheet in $($Workbook.Sheets)) {
$i = $sheet.Index
$Range = $Workbook.Sheets.Item($i).UsedRange
$Target = $Sheet.UsedRange.Find($Searchtext)
$First = $Target
Do {
$Target = $Range.Find($Target)
$Violation = [PSCustomObject]#{
Path = $xlsfile
Line = "SSN Found" + $target.text
LineNumber = "Sheet: " + $i
}
$Violation | Select-Object Path, Line, LineNumber | export-csv $outputpath\$PIIFile -append -NoTypeInformation
}
While ($NULL -ne $Target -and $Target.AddressLocal() -ne $First.AddressLocal())
}
$Excel.Quit()
}
Figured it out. Just a simple case of faulty logic in the loops.
Thanks to everyone who looked at this.
I am using PowerShell 2.0 on a Windows 7 desktop. I am attempting to search the enterprise CIFS shares for keywords/regex. I already have a simple single threaded script that will do this but a single keyword takes 19-22 hours. I have created a multithreaded script, first effort at multithreading, based on the article by Surly Admin.
Can Powershell Run Commands in Parallel?
Powershell Throttle Multi thread jobs via job completion
and the links related to those posts.
I decided to use runspaces rather than background jobs as the prevailing wisdom says this is more efficient. Problem is, is I am only getting partial resultant output with the multithreaded script I have. Not sure if it is an I/O thing or a memory thing, or something else. Hopefully someone here can help. Here is the code.
cls

Remove-Item C:\Users\user\Desktop\results.txt
$Throttle = 5 #threads
$ScriptBlock = {
Param (
$File
)
$KeywordInfo = Select-String -pattern KEYWORD -AllMatches -InputObject $File
$KeywordOut = New-Object PSObject -Property #{
Matches = $KeywordInfo.Matches
Path = $KeywordInfo.Path
}
Return $KeywordOut
}
$RunspacePool = [RunspaceFactory]::CreateRunspacePool(1, $Throttle)
$RunspacePool.Open()
$Jobs = #()
$Files = Get-ChildItem -recurse -erroraction silentlycontinue
ForEach ($File in $Files) {
$Job = [powershell]::Create().AddScript($ScriptBlock).AddArgument($File)
$Job.RunspacePool = $RunspacePool
$Jobs += New-Object PSObject -Property #{
File = $File
Pipe = $Job
Result = $Job.BeginInvoke()
}
}
Write-Host "Waiting.." -NoNewline
Do {
Write-Host "." -NoNewline

} While ( $Jobs.Result.IsCompleted -contains $false)
Write-Host "All jobs completed!"
$Results = #()

$Job.Pipe.EndInvoke($Job.Result) | Where {$_.Path} | Format-List | Out-File -FilePath C:\Users\user\Desktop\results.txt -Append -Encoding UTF8 -Width 512
}

This is the single threaded version I am using that works, including the regex I am using for socials.

I am hoping to build this answer over time as I dont want to over comment. I dont know yet why you are losing data from the multithreading but i think we can increase performace with an updated regex. For starters you have many greedy quantifiers that i think we can shrink down.
[sS][sS][nN]:*\s*\d{3}-*\d{2}-*\d{4}
Select-String is case insensitive by default so you dont need the portion in the beginning. Do you have to check for multiple colons? Since you looking for 0 or many :. Same goes for the hyphens. Perhaps these would be better with ? which matches 0 or 1.
ssn:?\s*\d{3}-?\d{2}-?\d{4}
This is assuming you are looking for mostly proper formatted SSN's. If people are hiding them in text maybe you need to look for other delimiters as well.
I would also suggest adding the text to separate files and maybe combining them after execution. If nothing else just to test.
Hoping this will be the start of a proper solution.
It turns out that for some reason the Select-String cmdlet was having problems with the multithreading. I don't have enough of a developer background to be able to tell what is happening under the hood. However I did discover that by using the -quiet option in Select-String, which turns it into a boolean output, I was able to get the results I wanted.
The first pattern match in each document gives a true value. When I get a true then I return the Path of the document to an array. When that is finished I run the pattern match against the paths that were output from the scriptblock. This is not quite as effective performance wise as I had hoped for but still a pretty dramatic improvement over singlethread.
The other issue I ran into was the read/writes to disk by trying to output results to a document at each stage. I have changed that to arrays. While still memory intensive, it is much quicker.
Here is the resulting code. Any additional tips on performance improvement are appreciated:
cls
Remove-Item C:\Users\user\Desktop\output.txt
$Throttle = 5 #threads
$ScriptBlock = {
Param (
$File

$Match = Select-String -pattern 'ssn:?\s*\d{3}-?\d{2}-?\d{4}' -Quiet -InputObject $File
if ( $Match -eq $true ) {
$MatchObjects = Select-Object -InputObject $File
$MatchOut = New-Object PSObject -Property #{
Path = $MatchObjects.FullName
}
}
Return $MatchOut
}
$RunspacePool = [RunspaceFactory]::CreateRunspacePool(1, $Throttle)
$RunspacePool.Open()
$Jobs = #()
$Files = Get-ChildItem -Path I:\ -recurse -erroraction silentlycontinue
ForEach ($File in $Files) {

How to retrieve the number of applications associated with a specific IIS AppPool via PowerShell command?
We can see the associated applications manually using:
Get-Item IIS:\AppPools\AppPoolName
However, if we manually want to select the Applications column, it is not possible. Also, the Applications column is not listed within | Get-Member *.
Why is the column not listed?
How to find the number of applications associated with a specific IIS AppPool using PowerShell?
The trick is: PowerShell established so-called "view definition files" which tell PowerShell how to format objects (e.g. whether the object is formatted as a a list or a table, which columns are displayed, etc.). Those files can be found at C:\Windows\System32\WindowsPowerShell\v1.0 and are all ending in .format.ps1xml.
To answer the original question: The file C:\Windows\System32\WindowsPowerShell\v1.0\Modules\WebAdministration\iisprovider.format.ps1xml contains the view definition for the AppPool type which defines a calculated column looking like this:
<TableColumnItem>
<ScriptBlock>
$pn = $_.Name
$sites = get-webconfigurationproperty "/system.applicationHost/sites/site/application[#applicationPool=`'$pn`'and #path='/']/parent::*" machine/webroot/apphost -name name
$apps = get-webconfigurationproperty "/system.applicationHost/sites/site/application[#applicationPool=`'$pn`'and #path!='/']" machine/webroot/apphost -name path
$arr = #()
if ($sites -ne $null) {$arr += $sites}
if ($apps -ne $null) {$arr += $apps}
if ($arr.Length -gt 0) {
$out = ""
foreach ($s in $arr) {$out += $s.Value + "`n"}
$out.Substring(0, $out.Length - 1)
}
</ScriptBlock>
</TableColumnItem>
This answers why the column itself is not a member of the AppPool type. The second question can be easily answered now extracting the necessary code from the "scriptlet" above:
$applicationsInAppPoolCount = #(Get-WebConfigurationProperty `"/system.applicationHost/sites/site/application[#applicationPool=`'$appPool`'and #path!='/']"` "machine/webroot/apphost" -name path).Count
I dealt with this same issue for many hours until finally arriving at the solution. The answer from D.R. was very helpful but it was not working for me. After some tweaks, I came up with the code below which retrieves the number of applications in an app pool.
I noticed that this part of the code nd #path!='/' threw off the count.
$appPool = "REPLACE ME with a value from your app pool"
#(Get-WebConfigurationProperty "/system.applicationHost/sites/site/application[#applicationPool=`'$appPool`']" "machine/webroot/apphost" -name path).Count
I ended up with the following Code (basically the same as above, but differently formatted)
$appPools = Get-ChildItem –Path IIS:\AppPools
foreach ($apppool in $apppools) {
$appoolName = $apppool.Name
[string] $NumberOfApplications = (Get-WebConfigurationProperty "/system.applicationHost/sites/site/application[#applicationPool='$appoolName']" "machine/webroot/apphost" -name path).Count
Write-Output "AppPool name: $appoolName has $NumberOfApplications applications"
}
I recently came across this post searching for ways to get the active Application Pools. The information provided above was great, but I kept digging to see if there was another way get this information. I was able to find a way to do this through Get-IISSite, which I used the following:
Get-IISSite | Select-Object -ExpandProperty Applications | Select-Object Path,ApplicationPoolName
I tested this on a server that only had one website, but if there are multiple sites on the server, you could also add VirtualDirectories for the Select.
I also had a need to just get a unique list of the Application Pools being used, so I did the following:
$appPoolInfo = Get-IISSite | Select-Object -ExpandProperty Applications | Select-Object Path,ApplicationPoolName
$appPoolInfo | Select-Object -Unique ApplicationPoolName
This gives what you are looking in an array.
Import-Module WebAdministration;
Get-ChildItem IIS:\AppPools >> AppPoolDetails.txt;
$appPoolDetails = Get-Content .\AppPoolDetails.txt;
$w = ($appPoolDetails |Select-String 'State').ToString().IndexOf("State");
$w = $w -1;
$res1 = $appPoolDetails | Foreach {
$i=0;
$c=0; `
while($i+$w -lt $_.length -and $c++ -lt 1) {
$_.Substring($i,$w);$i=$i+$w-1}}
Write-Host "First Column---";
$res1.Trim();
$j = $w + 1;
$w = ($appPoolDetails |Select-String 'Applications').ToString().IndexOf("Applications");
$w = $w -$j;
$res2 = $appPoolDetails | Foreach {
$i=$j;
$c=0; `
while($i+$w -lt $_.length -and $c++ -lt 1) {
$_.Substring($i,$w);$i=$i+$w-1}}
Write-Host "Second Column---";
$res2.Trim();
$lineLength=0
$appPoolDetails | Foreach {
if($lineLength -lt $_.TrimEnd().Length )
{
$lineLength = $_.TrimEnd().Length;
#Write-Host $lineLength;
}
}
$j = ($appPoolDetails | Select-String 'Applications').ToString().IndexOf("Applications");
$w = $lineLength;
$w = $w -$j;
#Write-Host $j $w;
$res3 = $appPoolDetails | Foreach {
$i=$j;
$c=0; `
while($i+$w -lt $_.length -and $c++ -lt 1) {
$_.Substring($i,$w);$i=$i+$w-1}}
Write-Host "Third Column---";
$res3;
I need a bit of help... I'm new to powershell and i want to Filter a List (csv). I would love to remove all lines with certain names in it. and cut the list down to the last month. In the script you can see how far i got till now.
param(
[Parameter(ValueFromPipeline=$true,HelpMessage="Enter CSV path(s)")]
[String[]]$Path = $null
)
if($Path -eq $null) {
Add-Type -AssemblyName System.Windows.Forms
$Dialog = New-Object System.Windows.Forms.OpenFileDialog
$Dialog.InitialDirectory = "$InitialDirectory"
$Dialog.Title = "Select CSV File(s)"
$Dialog.Filter = "CSV File(s)|*.csv"
$Dialog.Multiselect=$true
$Result = $Dialog.ShowDialog()
if($Result -eq 'OK') {
Try {
$Path = $Dialog.FileNames
}
Catch {
$Path = $null
Break
}
}
else {
Write-Host -ForegroundColor Yellow "Notice: No file(s) selected."
Break
}
}
$info=Import-Csv "$path" -Delimiter ';'
$info | Get-Member
$info | Format-Table
as you can see i tryed to link the path to a filebrowser.
For the purposes of discussion, I will assume that the full pathname of the CSV is in the variable $InputPath, and that you want to write the result to a CSV file whose full pathname is in the variable $OutputPath. I will also assume that the CSV file contains a column named 'Name', and that the value from the Name column that you want to exclude is in the variable $ExcludedName. Given that, you can simply do
Import-CSV -Path $InputPath | Where-Object {$_.Name -ne $ExcludedName} | Export-CSV -Path $OutputPath -NoTypeInformation
You can do this by my code,but dont forget that first row must contains names of column and delimiter must be ';' and $nameslist is array of names that you need delete:
$info=Import-Csv "D:\testdir\file2.csv" -Delimiter ';'
$nameslist=#('James','John','andrew')
foreach($i in $info){
if($nameslist -contains $i.Name){
$i.Name=""
}
$i|Export-Csv -Path "D:\testdir\file1.csv" -Delimiter ';' -NoTypeInformation -Force -Encoding UTF8 -Append
}
Try this:
$data = Import-Csv "Path" | Select-Object * -ExcludeProperty Names
$data | export-csv "Path" -Notype
This will cut the column names.
Try it first without using a function:
Import-Csv <Filename> | Where-Object {$_.<FieldName> -notlike "*<Value>*"}
Also, you might consider something like this:
[CmdletBinding()]
param (
[Parameter(ValueFromPipeline = $true, HelpMessage = "Enter CSV path(s)")]
[String[]]$Path = $(
Add-Type -AssemblyName System.Windows.Forms
$DialogProperties = #{
Title = 'Select CSV File(s)'
Filter = 'CSV File(s)|*.csv'
Multiselect = $True
}
$Dialog = New-Object System.Windows.Forms.OpenFileDialog -Property $DialogProperties
$Dialog.ShowDialog()
If ($Result -eq 'OK') {
$Path = $Dialog.FileNames
} Else {
Write-Error 'Notice: No file(s) selected.'
}
)
)
Process {
ForEach ($PathItem in $Path) {
Import-Csv $PathItem | Where-Object { $_.Name -notlike "*NotThisOne*" }
}
}
