I have a code that let me query one file version at the time.How can I query all file version inside of this registry key or if I just want to query specific files including firefox, chrome, etc.?
(Get-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\App Paths\communicator.exe').'(Default)' | ForEach-Object {
Get-ChildItem -Path $_ | Select-Object -ExpandProperty VersionInfo | Select FileDescription,ProductVersion
} | Format-Table -AutoSize
Instead of providing a literal path you should run Get-ChildItem on the "folder" the registry keys are contained in you are interested in. The result of this you pipe to your piece of code ... like this:
$Path = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\App Paths'
Get-ChildItem -Path $Path |
ForEach-Object {
Get-ItemProperty -Path $_.PSPath |
Select-Object -ExpandProperty '(default)' -ErrorAction SilentlyContinue |
ForEach-Object {
Get-Item -Path $_ -ErrorAction SilentlyContinue |
Select-Object FullName -ExpandProperty VersionInfo
}
} |
Format-Table -AutoSize

I'm trying to create a ps1 that can search multiple folders in multiple servers list, but seems didn't work. Something wrong with the *folder I guess. Sorry I'm very new to this.
$folders = get-content "C:\temp\folders.txt"
get-content c:\temp\servers.txt | Foreach {
Get-ChildItem -Path "c:\temp" -include *folders -Recurse -ErrorAction
silentlycontinue} | export-csv c:\Temp\results.csv
You're reading a textfile with (presumably) a list of server names to probe, but in your code you do nothing with that other than iterate this list..
Try
$folders = Get-Content 'C:\temp\folders.txt' # the list of foldernames to look for
Get-Content 'C:\temp\servers.txt' | ForEach-Object {
# construct a UNC path to the C:\Temp folder on the remote server (\\server\c$\temp)
# the $_ Automatic variable contains one servername in each iteration
$remotePath = "\\$_\C$\temp"
Get-ChildItem -Path $remotePath -Include $folders -Directory -Recurse -ErrorAction SilentlyContinue |
# select properties you need
Select-Object #{Name = 'ComputerName'; Expression = {$_}}, Name, FullName, CreationTime, LastAccessTime, LastWriteTime
} | Export-Csv 'C:\temp\results.csv' -NoTypeInformation
OR
Have the remote servers do the work and return the results to you. You may need to add -Credentials on Invoke-Command:
$folders = Get-Content 'C:\temp\folders.txt' # the list of foldernames to look for
Get-Content 'C:\temp\servers.txt' | ForEach-Object {
Invoke-Command -ComputerName $_ -ScriptBlock {
# this is running on the remote computer, so it uses it's own LOCAL path
# the $folders variable needs to be scoped '$using:folders', otherwise it is unknown in the scriptblock
Get-ChildItem -Path 'C:\temp' -Include $using:folders -Directory -Recurse -ErrorAction SilentlyContinue |
# select and output the properties you need
Select-Object #{Name = 'ComputerName'; Expression = {$env:COMPUTERNAME}}, Name, FullName, CreationTime, LastAccessTime, LastWriteTime
}
} | Export-Csv 'C:\temp\results.csv' -NoTypeInformation
I want to count files for every folder on an E-drive, and output the folder path and file count to a text file using PowerShell (version 2).
I have found this script, but it outputs to console. How do I change it to output to a text file?
Set-Location -Path E:\
Get-ChildItem -recurse | Where-Object{ $_.PSIsContainer } | ForEach-Object{ Write-Host $_.FullName (Get-ChildItem $_.FullName | Measure-Object).Count }
I think it would be best to get an array of resulting objects where you can store both the directory path and the number of files it contains. That way, you can afterwards show it in the console and also save it to a structured CSV file you can open in Excel.
This is for PowerShell 2:
# to keep the property order in PS version < 3.0, create an
# Ordered Dictionary to store the properties first
$dict = New-Object System.Collections.Specialized.OrderedDictionary
# now loop over the folders
$result = Get-ChildItem -Path 'E:\' -Recurse -Force -ErrorAction SilentlyContinue |
Where-Object { $_.PSIsContainer } |
ForEach-Object {
# add the results in the temporary ordered dictionary
$dict.Add('Directory', $_.FullName)
$dict.Add('Files', #(Get-ChildItem -Path $_.FullName -Force -ErrorAction SilentlyContinue |
Where-Object { !$_.PSIsContainer }).Count)
# and output a PSObject to be collected in array '$result'
New-Object PSObject -Property $dict
$dict.Clear()
}
# output on screen
$result | Format-Table -AutoSize
#output to CSV file
$result | Export-Csv -Path 'D:\Test\FileCount.csv' -NoTypeInformation
The -Force switch makes sure you also count items that otherwise can't be accessed by the user, such as hidden or system files.
Get-ChildItem c:\tmp -recurse |
Where-Object{ $_.PSIsContainer } |
ForEach-Object {
"$($_.Fullname) $((Get-ChildItem $_.FullName | Where-Object{!$_.PSIsContainer}).count)"
} |
Out-File c:\tmp\out.txt
You can use the > operator for this:
Set-Location -Path E:\
(Get-ChildItem -recurse | Where-Object{ $_.PSIsContainer } | ForEach-Object{ Write-Host $_.FullName (Get-ChildItem $_.FullName | Measure-Object).Count }) >"OUTPUTFILEPATH.txt"
I'm new to PS scripting (really, I started today) and, for a project, I need to create a .txt file with all the extensions from all shared folders on the local machine (a Windows file server).
I think I'm on the right path with this :
get-childitem -Path C:\test -Recurse | select extension -unique > $PSScriptRoot\ExtensionList.txt
It's doing exactly what I want for a given path and all subfolders but now I need to apply this to all shared folders on the machine.
I was able to list all the shared folder's path with this command :
$Shares= #(Get-WmiObject Win32_Share |
Select Name,Path,Type |
Where-Object { $_.Type -match '0|2147483648' } |
Select -ExpandProperty Path |
Select -Unique)
Write-Host $Shares
Now I'm stuck, I suppose I need to use the foreach command but I can't find the way to make it work.
Can someone help me put this together ?
Thanks,
You can try Get-SMBShare cmdLet:
Get-SMBShare | Foreach {
Get-ChildItem "\\$($_.name)" | Select-Object Extension -Unique
}
You're probably looking for something similar to this:
$Shares = #( Get-CimInstance Win32_Share | Where-Object { $_.Type -match '0|2147483648' } | Select -Unique )
ForEach ( $Share In $Shares ) { Get-ChildItem -Path $Share.Path -File -Recurse -ErrorAction Ignore | Select -Unique -ExpandProperty Extension }
I'll leave you to split the lines to match your particular style and to output to a file, (I'd advise that you consider using Out-File instead of > for that).
Thank you guys for your help! I was able to figure it out.
The following script will gather all extensions on shared folders, sort them, eliminate duplicates and empty lines, add "*' before the extension and create a file list.txt with the result.
#get shares
$Shares = #( Get-CimInstance Win32_Share |
Where-Object { $_.Type -match '0|2147483648' } |
Select -Unique )
#list all extensions
ForEach ( $Share In $Shares ) { Get-ChildItem -Path $Share.Path -File -Recurse -ErrorAction Ignore | Select -Unique -ExpandProperty Extension | out-file C:\extensions\List1.txt -append }
#remove empty lines
#(gc C:\extensions\List1.txt) -match '\S' | out-file C:\extensions\List2.txt
#Add * before extention type
gc C:\extensions\List2.txt | %{"*$_"} | out-file C:\extensions\List3.txt
#Sort by name
gc C:\extensions\List3.txt | sort | get-unique > C:\extensions\List4.txt
#Remove duplicates
$hash = #{}
gc C:\extensions\List4.txt |
%{if($hash.$_ -eq $null) { $_ }; $hash.$_ = 1} > C:\extensions\List.txt
#Delete list1-4
Remove-Item C:\extensions\List1.txt, C:\extensions\List2.txt, C:\extensions\List3.txt, C:\extensions\List4.txt
I'm a bit new to PowerShell. I have a working script returning -Line, -Character and -Word to a csv file. I can't figure out how to add the full name of the file into the csv.
get-childitem -recurse -Path C:\Temp\*.* | foreach-object { $name = $_.FullName; get-content $name | Measure-Object -Line -Character -Word} | Export-Csv -Path C:\Temp\FileAttributes.csv
I've tried using Write-Host and Select-Object, but I'm not sure about the syntax.
I've been using the following as a reference.
Results
This is what I'm after
Use Select-Object with a calculated property:
Get-Childitem -recurse -Path C:\Temp\*.* | ForEach-Object {
$fullName = $_.FullName
Get-Content $fullName | Measure-Object -Line -Character -Word |
Select-Object #{ Name = 'FullName'; Expression={ $fullName } }, *
} | Export-Csv -Path C:\Temp\FileAttributes.csv
Note:
Pass -ExcludeProperty Property to Select-Object to omit the empty Property column.
Pass -NoTypeInformation to Export-Csv to suppress the virtually useless first line (the type annotation) in the CSV.
I have script that selects .exe files with the specified name from the local folder and removes all files, except first.
$P variable is defined in param.
$P ="$($env:USERPROFILE)\Desktop\I"
Then I got this error
$C = Get-ChildItem $P -Filter *.exe| Where-Object Name -Like '*r_2-2*' | Sort-Object Name -Descending | Select-Object -ExpandProperty Name -Skip 1 | Remove-Item
Remove-Item : Cannot find path 'D:\FM\r_2-2.exe' because it does not exist.
At line:1 char:251
+ ... Descending | Select-Object -ExpandProperty Name -Skip 1 | Remove-Item
I know about foreach loop but want to use For-EachObject cmdlet instead.
You were quite close, if you want to use ForEach-Object:
Get-ChildItem $P -Filter *.exe | Where-Object Name -Like '*r_2-2*' | Select-Object -Skip 1 | ForEach-Object { remove-item $_.FullName -force }
To skip one first found result just Select-Object -Skip 1 is enough.
Remove-Item -Force also removes hidden and read-only files.
You can make the use of FullName parameter directly in your statement. Try this -
$C = Get-ChildItem $P -Filter *.exe| Where-Object Name -Like '*r_2-2*' | Sort-Object Name -Descending | Select-Object -ExpandProperty FullName -Skip 1
$c | ForEach-Object {Remove-Item -Path $_}
Use -Force parameter if you want to delete the hidden files too.
