Parse String with PowerShell - powershell

I'm getting a report for users. The 'membership of' is a string with all the groups per user between double quotes.
I need to place \ between each group. Now I have:
"GROUP1""GROUP2""GROUP3"
And I need:
"GROUP1"\"GROUP2"\"GROUP3"
Right now my code is:
foreach ($server in $servers) {
$Comp = $server
if (test-connection -computername $Comp -count 1 -quiet) {
([ADSI]"WinNT://$comp").Children | ?{$_.SchemaClassName -eq 'user'} | %{
$groups = $_.Groups() | %{$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)}
$_ | Select #{n='Server';e={$comp}},
#{n='DistingishedName';e={$_.AdsPath}},
#{n='Nombre';e={$_.FullName}},
#{n='Departamento';e={$_.Department}},
#{n='Email';e={$_.EmailAddress}},
#{n='Active';e={if ($_.PasswordAge -like 0) {$false} else {$true}}},
#{n='PasswordExpired';e={if ($_.PasswordExpired) {$true} else {$false}}},
#{n='LastLogin';e={$_.LastLogin}},
#{n='Description';e={$_.Description}},
#{n='Groups';e={$Groups -join '"'}}
} | Export-Csv $ReportFile -Delimiter ';' -Force -Encoding UTF8 -NoTypeInformation -Append
} else {
Write-Warning "Server '$Comp' is Unreachable hence Could not fetch data" 3>> $LogFile
}
}

try -join '"\"' instead of -join '"'

Selection of only one user from list

I have this script that I need to use to retrieve the data of a particular user "ADTuser" from a list of servers the script works well, but the output file with my user add also other users' detail that is not needed for my final output how can I filter it to only the user that I need.
get-content C:\servers.txt | foreach-object {
$Comp = $_
if (test-connection -computername $Comp -count 1 -quiet) {
([ADSI]"WinNT://$comp").Children | ?{$_.SchemaClassName -eq 'user' } | %{
$groups = $_.Groups() | %{$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)}
$_ | Select #{n='Computername';e={$comp}},
#{n='UserName';e={$_.Name}},
#{n='Memberof';e={$groups -join ';'}},
#{n='status'; e={if($groups -like "*Administrators*"){$true} else{$false}}}
}
} Else {Write-Warning "Server '$Comp' is Unreachable hence Could not fetch data"}
} | Out-File -FilePath C:\users.txt
This should be an easier way of doing what you're looking for, Get-CimInstance and Get-CimAssociatedInstance have been around since PowerShell 3:
Get-Content C:\servers.txt | ForEach-Object {
$computer = $_
try {
$query = Get-CimInstance Win32_UserAccount -Filter "Name='ADTuser'" -ComputerName $_ -ErrorAction Stop
foreach($object in $query) {
$membership = Get-CimAssociatedInstance -InputObject $object -ResultClassName Win32_Group -ComputerName $_
[pscustomobject]#{
Computername = $_
UserName = $object.Name
Memberof = $membership.Name -join ';'
Status = $membership.Name -contains 'Administrators'
}
}
}
catch {
Write-Warning "Server '$computer' is Unreachable hence Could not fetch data"
}
} | Export-Csv C:\users.csv -NoTypeInformation
If that doesn't work for you, your code would require a simple modification on your first filtering statement:
Where-Object { $_.SchemaClassName -eq 'user' -and $_.Name.Value -eq 'ADTuser' }
It's important to note that Test-Connection -ComputerName $_ -Count 1 -Quiet is not a relevant test for this script, this command is testing for ICMP response and adsi over WinNT requires RPC connectivity as well SMB.
Putting it all together with minor improvements the script would look like this:
Get-Content C:\servers.txt | ForEach-Object {
if (-not (Test-Connection -ComputerName $_ -Count 1 -Quiet)) {
Write-Warning "Server '$_' is Unreachable hence Could not fetch data"
return
}
$computer = $_
([adsi]"WinNT://$_").Children.ForEach{
if($_.SchemaClassName -ne 'user' -and $_.Name.Value -ne 'ADTuser') {
return
}
$groups = $_.Groups().ForEach([adsi]).Name
[pscustomobject]#{
Computername = $computer
UserName = $_.Name.Value
Memberof = $groups -join ';'
Status = $groups -contains 'Administrators'
}
}
} | Export-Csv C:\users.csv -NoTypeInformation

Out-File unnecessary characters

I have the script below which pings a list of machines, outputs the result to CSV and gets the lastlogontimestamp of the machine.
It works fine, except the lastlogontimestamp comes out like this:
CCC-APP01,172.22.100.15,#{lastLogonDate=07/25/2018 13:24:54}
How can I get rid of the extra characters: #{lastlogondate=...}?
$OutputCSV = "C:\TEMP\OUPingResults.csv"
$SearchLocation = "OU=AA,OU=Servers,DC=LocA,DC=XYZ,DC=com"
$Computers = Get-ADComputer -Filter * -SearchBase $SearchLocation |
Select Name |
Sort-Object Name
$Computers = $Computers.Name
$Headers = "ComputerName,IP Address,LastLogonTimeStamp"
$Headers | Out-File -FilePath $OutputCSV -Encoding UTF8
foreach ($computer in $Computers) {
Write-host "Pinging $Computer"
$Test = Test-Connection -ComputerName $computer -Count 1 -ErrorAction SilentlyContinue -ErrorVariable Err
if ($test -ne $null) {
$IP = $Test.IPV4Address.IPAddressToString
$LastLogonTimeStamp = Get-ADComputer $Computer -Prop CN,lastLogonTimestamp |
Select #{n="lastLogonDate";e={[datetime]::FromFileTime($_.lastLogonTimestamp)}}
$Output = "$Computer,$IP,$LastLogonTimeStamp"
$Output | Out-File -FilePath $OutputCSV -Encoding UTF8 -Append
} else {
$Output = "$Computer,$Err"
$Output | Out-File -FilePath $OutputCSV -Encoding UTF8 -Append
}
}
The expression ... |Select-Object #{N='SomeName';E={"SomeValue"}} will produce an object that has a property named SomeName with the value "SomeValue".
What you see in the output is a string representation of this object.
If you want only the value, change the $LastLogonTimeStamp assignment to:
$LastLogonTimeStamp = [datetime]::FromFiletime((Get-ADComputer $Computer -Prop lastLogonTimestamp).lastLogonTimestamp)

Add line breaks to Out-File cmdlet

I am trying to get the list of computers that has no antivirus but the out file is with computer names in one single line, can anyone help?
ForEach ($COMPUTER in (Get-ADComputer -Filter {OperatingSystem -notLike '*windows xp*' } | Select-Object -ExpandProperty Name))
{if(!(Test-Connection -Cn $computer -BufferSize 16 -Count 1 -ea 0 -quiet))
{write-host "cannot reach $computer" -f red}
else {
try
{
$AntiVirusProduct = Get-WmiObject -Namespace "root\SecurityCenter2" -Class AntiVirusProduct -ComputerName $computer -ErrorAction Stop
}
catch
{
Write-Warning "[ERROR] invalid namespace [$($computer)] : $_"
$noantivirus+=$computer
}
$noantivirus | out-file -Encoding Ascii -append c:\noantivirus.txt}}
You can try to join them by a NewLine:
$noantivirus -join [System.Environment]::NewLine | out-file -Encoding Ascii -append c:\noantivirus.txt
If this doesn't work, try with rn:
$noantivirus -join "`r`n" | out-file -Encoding Ascii -append c:\noantivirus.txt
I found it
$noantivirus = Add-Content c:\noantivirus.txt "`n$computer"

Avoiding or replacing multiple Where-Object statements

I have a script containing a function Create-RebootData containing child functions such as Full and Full has a child function named Generate-RebootData where the output variable $Global:result is created.
Within Full there are multiple Where-Object two statements to filter the $Global:result into by date and time. Example below.
Is there an easier method to accomplish this instead of the multiple Where-Object statements?
The desired result are
Set-StrictMode -Version 1.0
Function Create-RebootData{
[CmdletBinding(SupportsShouldProcess=$true,DefaultParameterSetName="ViewOnly")]
Param(
[Parameter(ParameterSetName="ViewOnly")]
[Switch]$ViewOnly,
[Parameter(ParameterSetName="Full")]
[Switch]$Full,
)
Switch ($PSCmdlet.ParameterSetName){
"ViewOnly"
{
ViewOnly
}
"Full"
{
Full
}
}#end switch
Function Full{
Generate-RebootData
$Global:result | Where-Object {$_ -like '*fri?2:00*' -and $_.MaintenanceWindow `
-notmatch 'all.da.servers' -and $_.Server -match "^ITD"} | % {"{0}" -f $_.Server} | `
Out-File D:\Scripts\Full-Servers.txt -Append
$Global:result | Where-Object {$_ -like '*fri?2:00*' -and $_.MaintenanceWindow `
-notmatch 'all.da.servers' -and $_.Server -match "^ITD"} | `
% {"{0}" -f $_.MaintenanceWindow -replace `
"^NA.+", "$((get-date).AddDays(1).ToString('MM-dd-yy')) 01:50"} | `
Out-File D:\Scripts\Full-Times.txt -Append
}
Function Generate-RebootData{
IF(Get-Command Get-SCOMAlert -ErrorAction SilentlyContinue){}ELSE{Import-Module OperationsManager}
"Get Pend reboot servers from prod"
New-SCOMManagementGroupConnection -ComputerName Server01
$AlertData = Get-SCOMAlert -Criteria "MyString" | Select NetbiosComputerName
New-SCOMManagementGroupConnection -ComputerName Server02
$AlertData += Get-SCOMAlert -Criteria "MyString" | Select NetbiosComputerName
"Remove duplicates"
$AlertDataNoDupe = $AlertData | Sort NetbiosComputerName -Unique
"Create hash table"
$table = #{}
"Populate hash table"
$MaintenanceWindow = Import-Csv D:\Scripts\MaintenanceWindow2.csv
$MaintenanceWindow | ForEach-Object {$table[$_.Computername] = $_.'Collection Name'}
"Create final object"
$Global:result = #{}
"Begin Loop"
$Global:result = $AlertDataNoDupe | ForEach-Object { [PSCustomObject] #{
Server=$_.NetbiosComputerName
MaintenanceWindow= if($table.ContainsKey($_.NetbiosComputerName)){
$table[$_.NetbiosComputerName]
}Else { "Not Found!"}
PingCheck=IF(Test-Connection -Count 1 $_.NetbiosComputerName -Quiet -ErrorAction SilentlyContinue){"Alive"}
ELSE{"Dead"}
LastReboot=Try{$operatingSystem = Get-WmiObject Win32_OperatingSystem -ComputerName $_.NetbiosComputerName -ErrorAction Stop
[Management.ManagementDateTimeConverter]::ToDateTime($operatingSystem.LastBootUpTime)}
Catch{"Access Denied!"}
} }
}
You can do it like this:
$Global:result | Where-Object {
$_ -like '*fri?2:00*' -and
$_.MaintenanceWindow -notmatch 'all.da.servers' -and
$_.Server -match '^ITD'
} | ForEach-Object {
'{0}' -f $_.Server | Out-File D:\Scripts\Full-Servers.txt -Append
'{0}' -f $_.MaintenanceWindow -replace '^NA.+',
'{0} 01:50' -f (Get-Date).AddDays(1).ToString('MM-dd-yy') | Out-File D:\Scripts\Full-Times.txt -Append
}
But I agree with Mathias' comment, this function probably should be refactored.

Append CSV output coding issue

Hi i created the below script to audit local admin groups on remote hosts. It works fine, but since it only outputs the data after it has went through all the hosts, i am afraid the array will run out of buffer space before it has a chance to export to csv, so i have been trying to have it create and append the output from each host as it goes through the list except i cannot get the headers to display on the first line and append additonal lines below it. Below is the output i get when i try to append. The italicized words should be the headers and the other info should be listed in the next row. what am i doing wrong?
#{Server=pc1; Members=Administrator;DistinguishedName=DC=Domain,DC=com
This is how it should look. It looks this way if i dont append and i let it create the csv after it has finished going through the list of hosts
Server Members DistinguishedName
host1 Administrator;Admin2 DC=DOMAIN,DC=COM
$servers= get-content "C:\Scripts\AD Audits\Local Admin\workstations.txt"
$output = "c:\temp\local admin audit $CurrentDate.csv"
$results = #()
$disconnected = "Did not respond"
foreach($server in $servers)
{
$connected = Test-Connection $server -count 1 -quiet
if ($connected) {
"$server responded" | Out-File -append "c:\temp\LocalAdmin goodhosts $CurrentDate.txt"}
else {
"$server did not respond" | Out-File -append "c:\temp\LocalAdmin badhosts $CurrentDate.txt"}
$group =[ADSI]"WinNT://$server/Administrators"
$members = $group.Members() | foreach {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null) }
$results += New-Object PsObject -Property #{
DistinguishedName = (get-adcomputer ($server) -properties * | select distinguishedname).distinguishedname
Server = $server
Members = $members -join ";"
}
$results | Export-Csv $Output -NoTypeInformation
}`
if($connected -eq $True) {
New-Object PSObject -Property #{
DistinguishedName = (Get-ADComputer $_).DistinguishedName
Server = $_
Members = $members -join ";"
}} else {write-host ""}
My suggestion is to use the pipeline rather than a foreach statement, so each object is written to the file as soon as it's processed.
$servers | ForEach-Object{
$connected = Test-Connection $_ -Count 1 -Quiet -ErrorAction SilentlyContinue
$state = if($connected) {"$_ responded"} else {"$_ did not respond"}
$state | Out-File -Append "c:\temp\LocalAdmin goodhosts $CurrentDate.txt"
$group =[ADSI]"WinNT://$_/Administrators,group"
$members = $group.Members() | ForEach-Object {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null) }
if($connected)
{
New-Object PSObject -Property #{
DistinguishedName = (Get-ADComputer $_).DistinguishedName
Server = $_
Members = $members -join ";"
}
}
} | Export-Csv $Output -NoTypeInformation
