El uso de Powershell OUT-FILE cambia los datos

Aquí hay un código de muestra que muestra información del disco físico en la consola (con muchas gracias a guyc@computerperformance.co.uk):

Get-WmiObject Win32_DiskDrive | % {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | % {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | % {
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID
        DiskModel   = $disk.Model
        Partition   = $partition.Name
        DriveLetter = $_.DeviceID
        VolumeName  = $_.VolumeName
        Size        = "{0:N}" -f ($_.Size/1GB) -as [float]
            FreeSpace   = "{0:N}" -f ($_.FreeSpace/1GB) -as [float]
      }
    }
  }
}

Pero quiero que la salida de la consola vaya a un archivo TXT. Cuando presento "Out-File", no sale nada en la consola, pero el resultado es diferente. No se divide (en GB) y muestra campos diferentes a los que seleccioné. Esto es lo que cambié:

Get-WmiObject Win32_DiskDrive | % {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | % {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | **Out-File -filepath "d:\DiskInfo.txt" -append** | % {
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID
        DiskModel   = $disk.Model
        Partition   = $partition.Name
        DriveLetter = $_.DeviceID
        VolumeName  = $_.VolumeName
        Size        = "{0:N}" -f ($_.Size/1GB) -as [float]
        FreeSpace   = "{0:N}" -f ($_.FreeSpace/1GB) -as [float]
      }
    }
  }
}

Así que cambié la forma en que implementé el OUT-FILE (poniéndolo en cada línea de salida):

Get-WmiObject Win32_DiskDrive | % {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | % {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | % {
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID | Out-File -filepath "d:\DiskInfo.txt" -append  
        DiskModel   = $disk.Model | Out-File -filepath "d:\DiskInfo.txt" -append 
        Partition   = $partition.Name | Out-File -filepath "d:\DiskInfo.txt" -append 
        DriveLetter = $_.DeviceID | Out-File -filepath "d:\DiskInfo.txt" -append 
        VolumeName  = $_.VolumeName | Out-File -filepath "d:\DiskInfo.txt" -append 
        Size        = "{0:N}" -f ($_.Size/1GB) -as [float] | Out-File -filepath "d:\DiskInfo.txt" -append 
        FreeSpace   = "{0:N}" -f ($_.FreeSpace/1GB) -as [float] | Out-File -filepath "d:\DiskInfo.txt" -append 
      }
    }
  }
}

Ahora no solo se divide entre la consola (encabezados) y el archivo TXT (valores), sino que también muestra diferentes variables que antes, y no hace la división, solo muestra el número de bytes, no GB.

¿Alguien puede aclararme el uso de OUT-FILE, o una mejor opción?

¡Gracias!

¿Alguien me puede dejar de usar out-file? ¿hay otras opciones?

Simplemente puede usar el operador de redirección de PowerShell >>al final del script.

    } >> DiskInfo.txt

Si quiere usarlo out-file, póngalo también al final del guión.

    } | out-file Diskinfo.txt

Notas:

• Cambiar DiskInfo.txtsegún corresponda.
• La ventaja de usar out-filees que los parámetros se pueden agregar out-filepero no>>

Get-Disk.ps1:

Get-WmiObject Win32_DiskDrive | % {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | % {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | % {
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID
        DiskModel   = $disk.Model
        Partition   = $partition.Name
        DriveLetter = $_.DeviceID
        VolumeName  = $_.VolumeName
        Size        = "{0:N}" -f ($_.Size/1GB) -as [float]
            FreeSpace   = "{0:N}" -f ($_.FreeSpace/1GB) -as [float]
      }
    }
  }
} >> DiskInfo.txt

Salida de ejemplo:

PS F:\test> .\Get-Disk
