收集计算机分区信息，去除列中的重复值（Excel）（空行）

收集计算机分区信息

$servers = gc D:serverlist.txt
$result = $results = $null
$results = @() 
foreach ($server in $servers)
{
 If ($server -eq "10")
 $UserName = "administrator"
 $serverpass ="abcd"
 $Password = ConvertTo-SecureString $serverpass -AsPlainText –Force
 $cred = New-Object System.Management.Automation.PSCredential($UserName,$Password)
 
 $disks = Get-WmiObject -Class Win32_LogicalDisk -ComputerName $server -Credential $cred -Filter "DriveType=3" 
 foreach ($disk in $disks)
    {
     $result = ""|Select Server,DeviceID,FreeSize,TotalSize,Free_Percentage
     $result.Server = $server
     $result.DeviceID = $disk.deviceid
     $result.FreeSize = ($disk.freespace/1GB).tostring("f1")
     $result.TotalSize = ($disk.size/1GB).tostring("f1")
     $result.Free_Percentage = "{0:p}" -f ($disk.freespace / $disk.size)
     $results += $result
    }
}
 $results |export-csv  D:disks.csv -Encoding default -NoTypeInformation

收集结果如下图所示：

要求去除A列中的重复字段，去除后如下：

代码如下：

$dd = import-csv d:disks.csv
#通过倒序方法去除列中重复值
for ($i=$dd.count-1;$i -ge 0;$i--)
{
$previous = $dd[$i-1].Server
$current = $dd[$i].Server
If ($current -eq $previous)
   {
    $dd[$i].Server = "" 
   }
}
$dd|export-csv d:disks2.csv -Encoding default -NoTypeInformation
