$test = #(gwmi win32_networkadapterconfiguration | select macaddress )
$test | ForEach-Object {
Write-Host $_.macaddress
$mac = $_.macaddress -replace ":", ""
$mac.Trim()
If (Test-Path "x:\$Mac") { $computer = $mac }
$Logfile = "x:\$Computer\$Computer.Log"
$File = "x:\$computer\$computer.ini"
$computer
$CompName = Get-Content $File | Select-Object -index 0
}
So the above script will not find the $file even though it is present. The x:\64006A849B90\64006A849B90.ini is present but i get this
ERROR: Get-Content : Cannot find path 'X:\64006A849B90\64006A849B90.ini' because it does not exist.
Anyone know why i cant use this - i know its something to do with the $mac value and making sure its a string but i have tried $mac.ToString() [String]$mac and trimming it and it will not see the path - any ideas? thanks
The strange thing is the value is being picked up hence the mac address being in the path but it wont find the path if that makes sense.
I think you might have other issues but assuming your files are named and exist where you expect the only problem you would have to deal with is potential nulls.
Do you have any adapters that do no have MAC Addresses? I have 3 right now. Using your code it will attempt to process those. If you were not aware of those I could see that being an issue. Easy to fix will a small code update
# Get the populated macs from all network adapters
$macs = Get-WmiObject win32_networkadapterconfiguration | Select-Object -ExpandProperty macaddress
ForEach($mac in $macs){
$mac = $mac.replace(":","")
$macFile = "x:\$mac\$mac.ini"
if(Test-Path $macFile){
# The ini file exists
$computer = Get-Content $macFile | Select-Object -Index 0
} else {
# Cant find the file
}
$computer
}
This could be simplified even further but I didn't want to do too much at once.
By using Select-Object -ExpandProperty macaddress we still get nulls but they are dropped by the pipeline so $macs would only contain strings of actual MACs.
The whole $computer = $mac should have worked but it was redundant so I removed that logic from your code.

I have an array and need to mapping a string inside a file by using the array then output the matched string to a file.
I tried it but when I found 2 match string in the file, in the output file only has 1 string.
$ArrayString = "Network controller TPX","Network controller SXCM", "Adapter controller CNA"
$GetFile = Get-Content .\File
foreach($string in $ArrayString ){
$GetFile | Select-String -Pattern $string | Out-File .\result.txt -Force
}
The content inside the file looks like this:
Network controller SXCM
Disable
*Enable
Admin Passwordfrom Startup Menu
*Disable
Enable
Adapter controller CNA
Disable
*Enable
Verify on every boot
*Disable
Enable
in some case the string in $ArrayString will matched 1 in the $Getfile and also matched 2 string.
Anyone can help me please. Thank you so much
The main issue with your code is that Out-File is inside the loop and without an -Append switch so each loop iteration is overwriting the file. Unfortunately, even if there is no match, the file would be overwritten due to the way Out-File was coded, seems like it opens the file stream in it's begin block which, shouldn't be the case and is one of many reasons why Set-Content should be the go to cmdlet when writing to a plain text file.
To explain the issue with Out-File visually:
# Create a temp file and write some content to it:
$file = New-TemporaryFile
'content' | Set-Content $file.FullName
Get-Content $file.FullName # => content
# `Process` block doesn't run on `AutomationNull.Value`,
# so, the expected would be, if nothing is received from pipeline,
# don't touch the file:
& { } | Set-Content $file.FullName
Get-Content $file.FullName # => 'content' // as expected
# Trying the same with `Out-File`
& { } | Out-File $file.FullName
Get-Content $file.FullName # => null // file was replaced
# dispose the file after testing...
$file | Remove-Item
A few considerations, Select-String can read files so Get-Content is not needed, and -Pattern can take an array of patterns to match. Here is the simplified version of your code.
$ArrayString = "Network controller TPX", "Network controller SXCM", "Adapter controller CNA"
Select-String -Path .\file.txt -Pattern $ArrayString |
ForEach-Object { $_.Matches.Value } | Set-Content result.txt
I try to uninstall a msi file, but when I try this via array I get an error (cant find installation package)
When I do the same but not in array - it works
for ($i=0; $i -lt $msiArrayClean.length; $i++){
Write-Host $msiArrayClean[$i]
& msiexec.exe /x $msiArrayClean[$i]
}
here the output of Write Host
How i come to $msiArrayClean
$msiCache = get-wmiobject Win32_Product | Where-Object Name -like "*7-Zip*" | Format-Table LocalPackage -AutoSize -HideTableHeaders
$msiString = $msiCache | Out-String
$msiArrayWithEmptyLines = $msiString -split "`n"
$msiArray = $msiArrayWithEmptyLines.Split('', [System.StringSplitOptions]::RemoveEmptyEntries)
$msiArrayCleanString = $msiArray | Out-String
$msiArrayClean = $msiArrayCleanString -split "`n"
A few caveats up front:
Format-* cmdlets output objects whose sole purpose is to provide formatting instructions to PowerShell's output-formatting system - see this answer. In short: only ever use Format-* cmdlets to format data for display, never for subsequent programmatic processing.
The CIM cmdlets (e.g., Get-CimInstance) superseded the WMI cmdlets (e.g., Get-WmiObject) in PowerShell v3 (released in September 2012). Therefore, the WMI cmdlets should be avoided, not least because PowerShell (Core) (version 6 and above), where all future effort will go, doesn't even have them anymore. For more information, see this answer.
Use of the Win32_Product WMI class is discouraged, both for reasons of performance and due to potentially unwanted side effects - see this Microsoft article.
An alternative - available in Windows PowerShell only (not in PowerShell (Core) 7+) - is to use the following to get uninstall command lines and execute them via cmd /c:
Get-Package -ProviderName Programs -IncludeWindowsInstaller |
ForEach-Object { $_.meta.attributes['UninstallString'] }
If you need to stick with Win32_Product:
# Get the MSI package paths of all installed products, where defined.
$msiCache = (Get-CimInstance Win32_Product).LocalPackage -ne $null
foreach ($msiPackagePath in $msiCache) {
if (Test-Path -LiteralPath $msiPackagePath) {
# Note that msiexec.exe runs *asynchronously*.
# Use Start-Process -Wait to wait for each call to complete.
& msiexec.exe /x $msiPackagePath
} else {
Write-Warning "Package not found: $msiPackagePath"
}
}
I don't like reaching to WMI, since its perfomance is the issue. I prefer to do it via registry and it worked for me many times. Code explanation in comments.
$name = "7-zip"
#Get all items from registry
foreach ($obj in Get-ChildItem "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall") {
#Get DisplayName property of registry
$dname = $obj.GetValue("DisplayName")
#Search for given name
if ($dname -like "*$name*") {
#Get uninstall string (it gets you msiexec /I{APPID})
$uninstString = $obj.GetValue("UninstallString")
foreach ($line in $uninstString) {
#Getting GUID from "{" to "}""
$found = $line -match '(\{.+\}).*'
if ($found) {
#If found - get GUID
$appid = $matches[1]
Write-Output "About to uninstall app $appid"
#Start uninstallation
Start-Process "msiexec.exe" -arg "/X $appid /qb" -Wait
}
}
}
}
Edit: Added solution with msi path after Nehat's comment as this works for me (I tried to minimize the code :))
$msiCache = get-wmiobject Win32_Product | Where-Object Name -like "*7-Zip*" | Format-Table LocalPackage -AutoSize -HideTableHeaders
foreach ($msi in $msiCache | Out-String) {
if ([string]::IsNullOrEmpty($msi)) {
continue
}
Write-Host $msi
Start-Process "msiexec.exe" -arg "/x $msi" -Wait
}
I'm trying to create a synchronization script in Powershell so that my applications in MDT are being copied on a regular basis to our main file server, based on the folder name (in MDT, applications are in one folder, where our main server has applications split depending on the department who uses them).
From what I read on the web, the best way would be to populate an array with "Get-ChildItem", which I kinda figured how to do (see code below).
After the array is populated though, I don't know how to search that array for specific results, nor do I know how to use those results with copy-item.
In a nutshell, here's what I need to do: Build an array using "Get-ChildItem", query the resulting array for specific folders, and have those folders be copied to specific destinations.
Here's the code I have so far:
$arr = Get-ChildItem \\slmtl-wds02.domain.inc\deploymentshare$\applications |
Where-Object {$_.PSIsContainer} |
Foreach-Object {$_.Name}
$sourcepath = \\slmtl-wds02.domain.inc\deploymentshare$\applications
$destSLARC = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLARCMTL
$destSLMTL = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLMTL
$destSLGLB = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLGLB
$destSLTECH = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLTECH
Thanks in advance for your help :)
$sourceLocation = "c:\analysis\"
$targetLocation = "c:\analysisCopy\"
$included = #("folder1", "folder2")
$result = #()
foreach ($i in $included){
$result += get-ChildItem $sourceLocation -filter $i | Where-Object {$_.PSIsContainer}
}
$result | foreach-Object { copy-item $_.FullName -Destination $targetLocation -Recurse}
Hope this works change the path D:\ to your desired path enter the name of folder you looking for
$Keyword=[Microsoft.VisualBasic.Interaction]::InputBox("Enter your Query")
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') | Out-Null
Get-ChildItem D:\ -recurse | Where-Object {$_.PSIsContainer -eq $fasle -and $_.Name -match "$keyword"} | Copy-Item -Destination d:\test
I hope someone can help me. I am pretty new to PowerShell and can't really script it myself with the exception of looking at existing code and modifying it.
I have found a PowerShell script that reports file share permissions for a specific share and recurses through the subfolders returning their permissions as well.
My problem is I need to do this with a lot of shares so would like to be able to provide the script with a text file containing the share names. I know I need to do a for each loop and read the names of the shares in a text file into an array but I don't know how to do this. I guess it's pretty simple for someone with more experience.
This is the script i have used with single entry.
http://mywinsysadm.wordpress.com/2011/08/17/powershell-reporting-ntfs-permissions-of-windows-file-shares/
#Set variables
$path = Read-Host "Enter the path you wish to check"
$filename = Read-Host "Enter Output File Name"
$date = Get-Date
#Place Headers on out-put file
$list = "Permissions for directories in: $Path"
$list | format-table | Out-File "C:\scripts\$filename"
$datelist = "Report Run Time: $date"
$datelist | format-table | Out-File -append "C:\scripts\$filename"
$spacelist = " "
$spacelist | format-table | Out-File -append "C:\scripts\$filename"
#Populate Folders & Files Array
[Array] $files = Get-ChildItem -path $path -force -recurse
#Process data in array
ForEach ($file in [Array] $files)
{
#Convert Powershell Provider Folder Path to standard folder path
$PSPath = (Convert-Path $file.pspath)
$list = ("Path: $PSPath")
$list | format-table | Out-File -append "C:\scripts\$filename"
Get-Acl -path $PSPath | Format-List -property AccessToString | Out-File -append "C:\scripts\$filename"
} #end ForEach
Sorry for the noob question. I plan to learn more when I have a bit more time but any help now would be massively appreciated.
Thanks in advance.
If you have a share name on each line within your text file can put all the shares into an array like this:
$path = "C:\ShareNames.txt"
$shareArray = gc $path
To access the first share you can use this syntax:
$shareArray[0]
I am retrieving the hosts file on a server with 5 DNS entries:
C:\Windows\System32\drivers\etc\hosts
Mine looks like this after the comments:
127.0.0.1 infspcpd8tx8e.rtmphost.com
127.0.0.1 infspkbpef39p.rtmphost.com
127.0.0.1 infspo99vn3ti.rtmphost.com
127.0.0.1 infspqx6l10wu.rtmphost.com
127.0.0.1 infspvdkqjhkj.rtmphost.com
In my hosts file I see them as 5 lines on top of eachother, but when I paste it here it has a space inbetween. This is the same when I use get-content on that file, but I wouldn't expect that to stop me.
So I have an array that is gotten like so:
$ACCOUNTS = Get-ChildItem "D:\cyst\accounts\" | select name
I then try to see if there are duplicate entries in the hosts file by checking the $accounts variable against the array I got containing the hosts file.
foreach ($rtmp in $ACCOUNTS) {
$HostsFile = Get-Content C:\Windows\System32\drivers\etc\hosts | ForEach-Object {[System.Convert]::ToString($_)}
#$rt[string]$data = $HostsFile
[string]$rtmpfull = $rtmp.name + ".rtmphost.com"
if ($HostsFile -contains $rtmpfull) { Write-Host "Host found in hosts file moving on..." }
else { echo "wrong"
}
}
It never matches and always returns false, I can't match anything.. please help - is it a type issue? I've googled this for DAYS but now i'm desperate and posting here.
I think you can probably speed that up by just dispensing with the foreach.
(Get-Content C:\Windows\System32\drivers\etc\hosts) -match [regex]::escape($rtmpfull)
Should match the entire hosts file at once.
$ACCOUNTS = Get-ChildItem "D:\cyst\accounts\"
foreach ($rtmp in $ACCOUNTS){
$found=$FALSE
foreach ($line in (gc C:\Windows\System32\drivers\etc\hosts)){
if(($line -match $rtmp) -and ($found -eq $TRUE)){
echo "$($matches[0]) is a duplicate"
}
if (($line -match $rtmp) -and ($found -eq $FALSE)){
echo "Found $($matches[0]) in host file..."
$found=$TRUE
}
}
}
Not elegant, but it will do the job.
This test:
if ($HostsFile -contains $rtmpfull)
is looking for $rtmpfull to match an entire line stored in $HostsFile. You want to check for a partial match like so;
if ($HostsFile | Foreach {$_ -match $rtmpfull})
BTW you can simplify this:
$HostsFile = Get-Content C:\Windows\System32\drivers\etc\hosts | ForEach-Object {[System.Convert]::ToString($_)}
to:
$HostsFile = Get-Content C:\Windows\System32\drivers\etc\hosts
By default, Get-Content will give you an array of strings where each element of the array corresponds to a line in the file.
