How to make Powershell to output the result to a csv - powershell

Question

I am trying to output to a csv file the result that I am getting from "Get-ChildItem"
I need to save only the LastWriteTime and the Name.
This is the Get-ChildItem output
I am trying something like
$pc = Get-WmiObject Win32_ComputerSystem
$file = Get-ChildItem -Path S:\Docker\RCT\repo\*xml -Recurse -Force
$DeviceObj = New-Object PSObject -Property #{
DeviceName = $pc.Name
FileName = $file.Name
FileDate = $file.LastWriteTime
}
$DeviceObjList += $DeviceObj
$DeviceObjList | Export-Csv -Path "$current_path\FileStatus.csv" -NoTypeInformation -Encoding UTF8
But my csv is not saving the file name and also the timestamp

Answer 1

Use a ForEach-Object to loop though your $file object
$pc = Get-WmiObject Win32_ComputerSystem
$file = Get-ChildItem -Path S:\Docker\RCT\repo\*xml -Recurse -Force
$file | ForEach-Object {
$DeviceObj = New-Object PSObject -Property #{
DeviceName = $pc.Name
FileName = $_.Name
FileDate = $_.LastWriteTime
}
$DeviceObjList += $DeviceObj
}
$DeviceObjList | Export-Csv -Path "$current_path\FileStatus.csv" -NoTypeInformation -Encoding UTF8
..but in fact, this is more efficient:
$pc = Get-WmiObject Win32_ComputerSystem
$file = Get-ChildItem -Path S:\Docker\RCT\repo\*xml -Recurse -Force
$DeviceObjList = $file | ForEach-Object {
[pscustomobject]#{
DeviceName = $pc.Name
FileName = $_.Name
FileDate = $_.LastWriteTime
}
}
$DeviceObjList | Export-Csv -Path "$current_path\FileStatus.csv" -NoTypeInformation -Encoding UTF8

You Don't need WMI to get the computer name, use the built-in variable $env:COMPUTERNAME
Use Calculated Properties to add the Computer name to the results.
Iteration not required here, just add the Export-Csv to the pipeline
So you can do that:
$file = Get-ChildItem -Path S:\Docker\RCT\repo\*xml -Recurse -Force
$File | Select #{N="DeviceName";E={$env:COMPUTERNAME}},Name,LastWriteTime |
Export-Csv -Path "$current_path\FileStatus.csv" -NoTypeInformation -Encoding UTF8
And if you want to make it shorter, you can use aliases and don't define any variables
gci S:\Docker\RCT\repo\*xml -R -Fo |
select #{N="DeviceName";E={$env:COMPUTERNAME}},Name,LastWriteTime |
epcsv "$current_path\FileStatus.csv" -NoT -En UTF8
