Currently have the following script that outputs some file data to a report. The file length is in bytes though and wondering how I can convert that to MB before outputting to the array.
$arr = #()
gci C:\stuff -recurse | ? {$_.PSIsContainer -eq $False} | % {
$obj = New-Object PSObject
$obj | Add-Member NoteProperty Directory $_.DirectoryName
$obj | Add-Member NoteProperty Name $_.Name
$obj | Add-Member NoteProperty Length $_.Length
$obj | Add-Member NoteProperty created $_.creationtime
$obj | Add-Member NoteProperty Access $_.LastAccessTime
$obj | Add-Member NoteProperty LastWritten $_.LastWriteTime
$obj | Add-Member NoteProperty Extension $_.Extension
$obj | Add-Member NoteProperty Owner ((Get-ACL $_.FullName).Owner)
$arr += $obj
}
$arr | Export-CSV -notypeinformation "c:\files.csv"
When converting into MB, just put brackets around it:
$obj | Add-Member NoteProperty Length ($_.Length/1MB)
or maybe more useful:
$obj | Add-Member NoteProperty MB ("{0:N3}" -f ($_.Length/1MB))
to only show the first three digits after the point.

I have an array of objects that are holding integer values.
$row = new-Object PSObject # create a new object to hold its data
$row | Add-Member -Name "sheet_number" -MemberType NoteProperty -Value 1
$row | Add-Member -Name "frame_number" -MemberType NoteProperty -Value 2
$row | Add-Member -Name "sheet_height" -MemberType NoteProperty -Value 1200
$row | Add-Member -Name "frame_height" -MemberType NoteProperty -Value 1200
$row | Add-Member -Name "frame_width" -MemberType NoteProperty -Value 3300
$row | Add-Member -Name "orientation" -MemberType NoteProperty -Value 0
$frames += $row
this is in a for loop intended to iterate through several times. But the sheet_number property should only have a couple values. what I need is to sum up the values in frame_width where the sheet_number is the same.
Pseudo Code:
sheet_width = sum of frame_width where sheet number = 1
Use a combination of Where-Object, ForEach-Object, and Measure-Object:
$sum = (
$frames |
Where-Object sheet_number -eq 1 |
ForEach-Object frame_width |
Measure-Object -Sum
).Sum
To do it for all sheet numbers, additionally use Group-Object:
$arrayOfSums =
$frames |
Group-Object sheet_number |
ForEach-Object {
($_.Group.frame_width | Measure-Object -Sum).Sum
}
I am trying to fill a csv file with all the attributes of the files contained within a folder. I have troubles recovering the fileversion & assembly
$arr = #()
gci C:\Temp -recurse | ? {$_.PSIsContainer -eq $False} | % {
$obj = New-Object PSObject
$obj | Add-Member NoteProperty Directory $_.DirectoryName
$obj | Add-Member NoteProperty Name $_.Name
$obj | Add-Member NoteProperty Size (Get-Item $_.Length/1MB)
$obj | Add-Member NoteProperty Owner ((Get-ACL $_.FullName).Owner)
$obj | Add-Member NoteProperty LastAccess $_.LastAccessTime
$obj | Add-Member NoteProperty Extension $_.Extension
$obj | Add-Member NoteProperty Creation $_.CreationTime
$obj | Add-Member NoteProperty LastWrite $_.LastWriteTime
$obj | Add-Member NoteProperty ReadOnly $_.IsReadOnly
$obj | Add-Member NoteProperty FullName $_.FullName
$obj | Add-Member NoteProperty Date (Get-Date -format "yyyy-MM-d HH:mm")
$obj | Add-Member NoteProperty Version ($_.FileVersion)
$obj | Add-Member NoteProperty Assembly ($_.AssemblyVersion)
$arr += $obj
}
$arr | Export-CSV -notypeinformation "c:\temp\File\report.csv"
try this
$arr = #()
gci C:\Temp -recurse -File -Filter *.dll | % {
$obj = New-Object PSObject
$obj | Add-Member NoteProperty Directory $_.DirectoryName
$obj | Add-Member NoteProperty Name $_.Name
$obj | Add-Member NoteProperty Size (Get-Item $_.Length/1MB)
$obj | Add-Member NoteProperty Owner ((Get-ACL $_.FullName).Owner)
$obj | Add-Member NoteProperty LastAccess $_.LastAccessTime
$obj | Add-Member NoteProperty Extension $_.Extension
$obj | Add-Member NoteProperty Creation $_.CreationTime
$obj | Add-Member NoteProperty LastWrite $_.LastWriteTime
$obj | Add-Member NoteProperty ReadOnly $_.IsReadOnly
$obj | Add-Member NoteProperty FullName $_.FullName
$obj | Add-Member NoteProperty Date (Get-Date -format "yyyy-MM-d HH:mm")
$obj | Add-Member NoteProperty Version ($_.VersionInfo.FileVersion)
$obj | Add-Member NoteProperty Assembly ([Reflection.AssemblyName]::GetAssemblyName($_.FullName).Version)
$arr += $obj
}
$arr | Export-CSV -notypeinformation "c:\temp\File\report.csv"
you can simplify your code like this
gci C:\Temp -recurse -File -Filter *.dll | % {
New-Object PSObject -Property #{
Directory= $_.DirectoryName
Name= $_.Name
Size= $_.Length/1MB
Owner= ((Get-ACL $_.FullName).Owner)
LastAccess= $_.LastAccessTime
Extension= $_.Extension
Creation= $_.CreationTime
LastWrite= $_.LastWriteTime
ReadOnly= $_.IsReadOnly
FullName= $_.FullName
Date= (Get-Date -format "yyyy-MM-d HH:mm")
Version= ($_.VersionInfo.FileVersion)
Assembly= ([Reflection.AssemblyName]::GetAssemblyName($_.FullName).Version)
}
} | Export-CSV -notypeinformation "c:\temp\File\report.csv"
1)The issue what you are facing is because of permission. Try running the script in elevated mode(run as administrator).
2)You should not try to save anything under C:\temp folder. Better to create a folder in D:\ or E:\ and put it over there as D:\temp_dump\report.csv
3)if you are putting get-item on the size, then that is not a valid one since you have to pick whatever inside the folder.
Below Script is working fine.

In order to get fileversion you have to use this:
$obj | Add-Member NoteProperty Version ($_.VersionInfo.FileVersion)
You cannot get AssemblyVersion from VersionInfo
I will be hosting a file on a remote server (read-only) and asking people to run the file on their machines to gather installed program information. I want the file to be saved to their Desktop in their user space, so that I can then have them send it to us.
I have the script, but I'm not managing to obtain information from both "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", and "Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" in the same output file. I'm obviously missing something inherently obvious, as PowerShell is clearly able to do this, and I'm asking that someone please save me from my PEBKAC issue!
Thank you in advance, appreciated!
Here is my code;
$computers = "$env:computername"
$array = #()
foreach($pc in $computers){
$computername=$pc
$UninstallKey="SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall"
$UninstallKey="Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall"
$reg=[microsoft.win32.registrykey]::OpenRemoteBaseKey('LocalMachine',$computername)
$regkey=$reg.OpenSubKey($UninstallKey)
$subkeys=$regkey.GetSubKeyNames()
Write-Host "$computername"
foreach($key in $subkeys){
$thisKey=$UninstallKey+"\\"+$key
$thisSubKey=$reg.OpenSubKey($thisKey)
$obj = New-Object PSObject
$obj | Add-Member -MemberType NoteProperty -Name "ComputerName" -Value $computername
$obj | Add-Member -MemberType NoteProperty -Name "DisplayName" -Value $($thisSubKey.GetValue("DisplayName"))
$obj | Add-Member -MemberType NoteProperty -Name "DisplayVersion" -Value $($thisSubKey.GetValue("DisplayVersion"))
$obj | Add-Member -MemberType NoteProperty -Name "InstallLocation" -Value $($thisSubKey.GetValue("InstallLocation"))
$obj | Add-Member -MemberType NoteProperty -Name "Publisher" -Value $($thisSubKey.GetValue("Publisher"))
$array += $obj
}
}
$array | Where-Object { $_.DisplayName } | select ComputerName, DisplayName, DisplayVersion, Publisher | export-csv C:\Users\$env:username\Desktop\Installed_Apps.csv
Right now the following two lines set the same variable:
$UninstallKey="SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall"
$UninstallKey="Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall"
Use this:
$UninstallKey = #(
'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall',
'SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
)
Then wrap the real logic in:
$UninstallKey | ForEach-Object {
$regkey=$reg.OpenSubKey($_)
# the rest of your logic here
}
Got a small problem with sorting percent numbers.
I just wrote a simple script to test:
function get-percent{
$obj1 = New-Object PSObject
$percentUsed1="{0:P0}" -f (100/100)
$obj1 | Add-Member -membertype NoteProperty -Name 'Percent' -Value $percentUsed1
$obj2 = New-Object PSObject
$percentUsed2="{0:P0}" -f (99/100)
$obj2 | Add-Member -membertype NoteProperty -Name 'Percent' -Value $percentUsed2
$obj3 = New-Object PSObject
$percentUsed3="{0:P0}" -f (8/100)
$obj3 | Add-Member -membertype NoteProperty -Name 'Percent' -Value $percentUsed3
$obj4 = New-Object PSObject
$percentUsed4="{0:P0}" -f (70/100)
$obj4 | Add-Member -membertype NoteProperty -Name 'Percent' -Value $percentUsed4
write $obj1
write $obj2
write $obj3
write $obj4
}
get-percent | sort-object 'Percent' -descending |ft
Here is what i get:
Percent
99%
8%
70%
100 %
Normally, I should have: 100 % , 99%, 70%...
Any ideas guys ?
Thx.
Try:
get-percent | sort-object { [INT]($_.percent -replace '%') } -descending
In this way sort-object can sort by [INT] and not by [String] as before.
Can someone help me understand why the $_ works differently for the Add-Member function than it seems to for other PowerShell functions? There must be some nuance that I am missing here.
Using the sample CSV file below, the first 3 examples work fine. The fourth, which seems pretty straightforward, does not. The error Powershell returns is:
The variable '$_' cannot be retrieved because it has not been set.
Is this "normal" or have I miscoded something?
Thanks in advance.
Test.csv
Column1,Column2, Column3
Rock,1,abc
Paper,2,efg
Scissors,3,hij
$obj = Import-CSV "C:\test.csv"
(1) $obj | Add-Member -MemberType NoteProperty -Name IdNumber -value "ROCK" -PassThru| Format-Table
(2) $obj | ForEach-Object { $_ | Add-Member -MemberType NoteProperty -Name IdNumber -value $_.Column1 ; $_} | Format-Table
(3) $obj | ForEach-Object { Add-Member -InputObject $_ -MemberType NoteProperty -Name IdNumber -value $_.Column1 ; $_ } | Format-Table
(4) $obj | Add-Member -MemberType NoteProperty -Name IdNumber -value $_.Column1 -PassThru| Format-Table
When you do this:
$obj | Add-Member -MemberType NoteProperty -Name IdNumber -value $_.Column1 -PassThru
You are accessing $_ outside of a pipeline bound context e.g. inside a foreach-object expression or within a scriptblock value specified for a pipeline bound parameter. The Value parameter is not pipeline bound. If it were you would be able to do this:
$obj | Add-Member -MemberType NoteProperty -Name IdNumber -value {$_.Column1} -PassThru
As it stands, the easiest way to do what you want is:
$obj | ForEach-Object { Add-Member -Inp $_ NoteProperty -Name IdNumber -Value $_.Column1 -PassThru } | Format-Table
