In powershell running the below code in a script block and having issue running it
foreach($list in $an){
Write-Host "on loop :" $loop
Write-Host "Checking on VM : "$list.vm
$checkdata = (([datetime]$currentdate) - ([datetime]$list.Created.ToString().split(" ")[0])).Days
Write-Host "Check data " $checkdata
IF($checkdata -gt 2){
Write-Host "on Dupe : " $dupe
#$datecreated = $sizeinGGB = $diff = $null | Out-Null
$datecreated = ($list.Created.ToString().split(" ")[0])
Write-Host $datecreated
$sizeinGGB = [INT]$list.SizeGB
Write-Host $sizeinGGB
$diff = ((([datetime]$currentdate) - ([datetime]$list.Created)).Days)
Write-Host $diff
$repo = [ordered] #{
vm = $list.vm
SNapshotname = $list.Name
DateCreated = $datecreated
Snapshotold = $diff
SizeinGB = $sizeinGGB
}
New-Object PSobject -Property $repo
$dupe ++
}ELSE{
Write-Host $list.vm " : Looks Good"
}
$loop ++
}
If I remove the $repo assignment statement my script is working good. If I put that on the script then script just stop execution on $repo block

Good morning everyone.
I found this script on the InterWeb's which works phenominal. HOWEVER... No matter what I try, and where I put it, I can't seem to get it to do the results to an out-file.
What the hell am I doing wrong, and where does the variable need to go?

$search = New-Object DirectoryServices.DirectorySearcher([ADSI]"")
$search.filter = "(servicePrincipalName=*)"
## You can use this to filter for OU's:
## $results = $search.Findall() | ?{ $_.path -like '*OU=whatever,DC=whatever,DC=whatever*' }
$results = $search.Findall()
foreach( $result in $results ) {
$userEntry = $result.GetDirectoryEntry()
Write-host "Object Name = " $userEntry.name -backgroundcolor "yellow" -foregroundcolor "black"

The goal : get all logged in / logged out users from the system.
Those users who logged in / logged out by using remote desktop connection.
My script :
Param(

[datetime]$StartTime = "January 1, 1970"
)
foreach ($Server in $ServersToQuery) {
$LogFilter = #{
LogName = 'Microsoft-Windows-TerminalServices-LocalSessionManager/Operational'

StartTime = $StartTime
}

I really do not understand ps1 scripts. I've found this script but i want to use it for my purposes.
When i try to execute it with c# :
Scenario 1 :
string scriptText = "C:\\MyPath\\script.ps1";
try
{
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptText);
Collection<PSObject> results = pipeline.Invoke();
It throws an error :
ps1 is not digitally signed.
Second scenario :
using (PowerShell PowerShellInstance = PowerShell.Create())
{
PowerShellInstance.AddScript(str_Path);
Collection<PSObject> PSOutput = PowerShellInstance.Invoke();
if (PowerShellInstance.Streams.Error.Count > 0)
{
// error records were written to the error stream.
// do something with the items found.
}
}
Streams are always empty. Actually it always count 0 rows.
Any idea/suggestion how to get this done ?
I used Write-Output instead of Write-Host into the end of the script without generating csv file. Credits to this.
I am trying to create a thread that will use a shared variable (between main session and the thread)
plus the give the thread ability to use outside function from the main code
I have managed to pass the function for the thread to use
and i have managed to pass read only variable.
my problem is that if i am changing the value of the variable inside the thread and then i try to read it from the main session - i can not see the change in the value, therefore its not shared.
How do i do that?
My goal is to have one thread in the end.
this is my code:
$x = [Hashtable]::Synchronized(#{})
$global:yo = "START"
Function ConvertTo-Hex {
#Write-Output "Function Ran"
write-host "hi"
$x.host.ui.WriteVerboseLine("===========")
write-host $yo
$yo="TEST"
write-host $yo
}
#endregion
$rs = [RunspaceFactory]::CreateRunspace()
$rs.ApartmentState,$rs.ThreadOptions = "STA","ReUseThread"
$rs.Open()
$rs.SessionStateProxy.SetVariable("x",$x)
ls
# create an array and add it to session state
$arrayList = New-Object System.Collections.ArrayList
$arrayList.AddRange(('a','b','c','d','e'))
$x.host = $host
$sessionstate = [system.management.automation.runspaces.initialsessionstate]::CreateDefault()
$sessionstate.Variables.Add((New-Object System.Management.Automation.Runspaces.SessionStateVariableEntry('arrayList', $arrayList, $null)))
$sessionstate.Variables.Add((New-Object System.Management.Automation.Runspaces.SessionStateVariableEntry('x', $x, $null)))
#$sessionstate.Variables.Add((New-Object System.Management.Automation.Runspaces.SessionStateVariableEntry('yo', $yo, $true)))
$sessionstate.Commands.Add((New-Object System.Management.Automation.Runspaces.SessionStateFunctionEntry -ArgumentList 'ConvertTo-Hex', (Get-Content Function:\ConvertTo-Hex -ErrorAction Stop)))
$runspacepool = [runspacefactory]::CreateRunspacePool(1, 2, $sessionstate, $Host)
$runspacepool.Open()
$ps1 = [powershell]::Create()
$ps1.RunspacePool = $runspacepool
$ps1.AddScript({
for ($i = 1; $i -le 15; $i++)
{
$letter = Get-Random -InputObject (97..122) | % {[char]$_} # a random lowercase letter
$null = $arrayList.Add($letter)
start-sleep -s 1
}
})
$ps1.AddParameter(#($yo))
# on the first thread start a process that adds values to $arrayList every second
$handle1 = $ps1.BeginInvoke()
# now on the second thread, output the value of $arrayList every 1.5 seconds
$ps2 = [powershell]::Create()
$ps2.RunspacePool = $runspacepool
$ps2.AddScript({
Write-Host "ArrayList contents is "
foreach ($i in $arrayList)
{
Write-Host $i -NoNewline
Write-Host " " -NoNewline

Here is my Powershell code that when i execute it, it will continually loop while waking up my internal sites
$urlFile = "C:\Users\lfouche\Desktop\url\url.txt"
foreach($site in Get-Content $urlFile){
function WakeUp([string] $url)
{
Write-Host "Waking up $url ..." -NoNewLine
$client = new-object system.net.WebClient
$client.UseDefaultCredentials = $true
$null = $client.OpenRead($url)
$client.Dispose()
Write-Host " Ok"
}
#(
Get-Content $urlFile
) | % { WakeUp $_ }
}
Well, your script can generally be improved, however I think the error is that you already iterate over Get-Content $urlFile within your foreach condition and also in the loop. Try this:
# define the wake up function once
function WakeUp
{
Param
(
[string] $url
)
Write-Host "Waking up $url ..." -NoNewLine
$client = new-object system.net.WebClient
$client.UseDefaultCredentials = $true
$null = $client.OpenRead($url)
$client.Dispose()
Write-Host " Ok"
}
$urlFile = "C:\Users\lfouche\Desktop\url\url.txt"
$sites = Get-Content $urlFile
foreach($site in $sites)
{
# call wake up for each site
WakeUp $site
}
I am battling with a PowerShell script that captures all SQL Failed jobs for the past day and exports it to .CSV
Please view code below.
param (
#[string]$serverInstance = '03RNB-VSQLPRD4\SQLPRD04
)
begin {
[void][reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
}
process {
try {
Write-Verbose "List failed SQL Server jobs using SMO..."
$serverInstance = Get-Content "C:\MountSpaceCollector\SQLJobFailures\servers2.txt";
$server = new-object Microsoft.SqlServer.Management.Smo.server $serverInstance
$results = #()
$reasons = #()
$jobs = $server.jobserver.jobs | where-object {$_.isenabled}
# Process all SQL Agent Jobs looking for failed jobs based on the last run outcome
foreach ($job in $jobs) {
[int]$outcome = 0
[string]$reason = ""
# Did the job fail completely?
if ($job.LastRunOutcome -eq "Failed") {
$outcome++
$reasons += "Job failed: " + $job.name + " Result: " + $job.LastRunOutcome
# Did any of the steps fail?
foreach ($jobStep in $job.jobsteps) {
if ($jobStep.LastRunOutcome -ne "Succeeded") {
$outcome++
$reasons += "Step failed: " + $jobStep.name + " Result: " + $jobStep.LastRunOutcome
}
}
}
if ($outcome -gt 0) {
$jobFailure = New-Object -TypeName PSObject -Property #{
Name = $job.name
LastRunDate = $job.lastrundate
LastRunOutcome = $reasons
}
$results += $jobFailure
}
}
Write-Output $results | Export-CSV -Path 'C:\MountSpaceCollector\SQLJobFailures\SQLJobFailures.csv' -Delimiter '|'
}
catch [Exception] {
Write-Error $Error[0]
$err = $_.Exception
while ( $err.InnerException ) {
$err = $err.InnerException
Write-Output $err.Message
Write-Output $results
}
}
}
But It Exports all except the last field (LastRunOutcome). It only displays "System.Object[]"?
Can anyone please assist with this as I do not know what I am doing wrong?
It's because $Reasons is an object, more specifically an array. You need to format the reasons differently, as a string for instance, to be able to have it appear in the CSV normally.
Perhaps you meant to use the string $Reason that you declare, but don't use?
