Question

我有下面的csv

  Total Devices Affected      Comments 
          5                 Host1.Domain
                            Host2.Domain
                            Host3.Domain
                            Host4.Domain
                            Host5.Domain

          4                 Host1.Domain
                            Host2.Domain
                            Host3.Domain
                            Host4.Domain

我希望能够从每个单元格中删除条目Host2.Domain和Host3.Domain而不删除整个单元格。我只使用Windows PowerShell。这可能吗？

$data = Import-Csv .\acas.csv

 foreach($title in $data)

{
$totaldevices = $title."Total Devices Affected"
$comments = $title."Comments"
}

假设csv中的Comments字段是一个多行字符串，请按照以下简单for循环执行此操作：

# Define the host names we want to remove
$PendingRemoval = "Host2.Domain","Host3.Domain"

# Import the original data set
$Data = Import-Csv .\original.csv

for($i = 0; $i -lt $data.Count; $i++)
{
    # Grab all hostnames from the comments field
    $Comments = $Data[$i].Comments -split "`r?`n"

    # Filter out unwanted ones
    $Comments = $Comments |Where-Object {$_ -notin $PendingRemoval}

    # Update original row
    $Data[$i].Comments = $Comments -join [System.Environment]::NewLine
}

# Export it to a new csv
$Data |Export-Csv .\updated.csv

删除CSV单元格中的多个条目
