如何在输出 csv 中添加空行？
How to add empty rows in output csv?
我正在使用以下脚本生成磁盘 space 利用率报告，但输出的 csv 文件在不同服务器之间没有任何 spaces/blank 行，那么我如何添加 spaces/blank 行以提高可读性 ??
$LogDate = get-date -f yyyyMMddhhmm
$File = Get-Content -Path C:\StorageReport\Servers.txt
$DiskReport = ForEach ($Servernames in ($File))
{Get-WmiObject win32_logicaldisk <#-Credential $RunAccount#> `
-ComputerName $Servernames -Filter "Drivetype=3" `
-ErrorAction SilentlyContinue
}
$DiskReport |
Select-Object @{Label = "Server Name";Expression = {$_.SystemName}},
@{Label = "Drive Letter";Expression = {$_.DeviceID}},
@{Label = "Total Capacity (GB)";Expression = {"{0:N1}" -f( $_.Size / 1gb)}},
@{Label = "Free Space (GB)";Expression = {"{0:N1}" -f( $_.Freespace / 1gb ) }},
@{Label = 'Free Space (%)'; Expression = {"{0:P0}" -f ($_.freespace/$_.size)}} |
Export-Csv -path "C:\StorageReport\DiskReport_$logDate.csv" -NoTypeInformation
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn;
$messageParameters = @{
Subject = "Weekly Server Storage Report"
Body = "Attached is Weekly Server Storage Report.All reports are located in C:\StorageReport\, but the
most recent is sent weekly"
From = "Email name1 <Email.name1@domainname.com>"
To = "Email name1 <Email.name1@domainname.com>"
CC = "Email name2 <Email.name2@domainname.com>"
Attachments = (Get-ChildItem C:\StorageReport\*.* | sort LastWriteTime | select -last 1)
SmtpServer = "SMTPServerName.com"

尽管我的 Excel (2016) 版本接受（并显示）输入 csv 中的空行，但我不能保证其他版本也会如此，所以我认为最好在 csv 中包含仅包含逗号的行，有效地添加了所有字段为空的行。
为此，您可以在 循环中输出 Csv 文件 ，在循环中您使用添加的 -Append 开关迭代不同的服务器。
$LogDate = Get-Date -Format 'yyyyMMddHHmm'
$File = Get-Content -Path C:\StorageReport\Servers.txt
$OutFile = Join-Path -Path 'C:\StorageReport' -ChildPath "DiskReport_$LogDate.csv"
# because we now are Appending to the csv, we must make sure we start off with a new file
if (Test-Path -Path $OutFile -PathType Leaf) {
Remove-Item -Path $OutFile -Force
}
foreach ($Server in $File) {
Get-WmiObject Win32_LogicalDisk -ComputerName $Server -Credential $RunAccount -Filter "Drivetype=3" -ErrorAction SilentlyContinue |
Select-Object @{Label = 'Server Name';Expression = {$_.SystemName}},
@{Label = 'Drive Letter';Expression = {$_.DeviceID}},
@{Label = 'Total Capacity (GB)';Expression = {'{0:N1}' -f ( $_.Size / 1gb)}},
@{Label = 'Free Space (GB)';Expression = {'{0:N1}' -f ( $_.Freespace / 1gb ) }},
@{Label = 'Free Space (%)'; Expression = {'{0:P0}' -f ($_.freespace/$_.size)}} |
Export-Csv -Path $OutFile -NoTypeInformation -Append
# add a line with just commas (empty fields) below this server info to the file
Add-Content -Path $OutFile -Value (',' * 4)
}
接下来，继续发送电子邮件。我对此的评论是简单地做
Attachments = $OutFile

查看您在评论中显示的错误，我怀疑您读取服务器名称的输入文件以空行开头，或者服务器名称周围有空格，这会导致 Get-WmiObject 命令失败。
当此 returns $null 时，将没有属性可写入 CSV 文件，并且由于 -ErrorAction SilentlyContinue 无论如何都无法阻止脚本将 zilch 写入文件.
下面的代码在这方面做了大量的 error-checking，包括读取文件和去除空行和空格，预先测试服务器是否 on-line 现在它使用 try{..} catch{..}块。
$LogDate = Get-Date -Format 'yyyyMMddHHmm'
# make sure you skip empty or whitespaace only lines and trime the values
$File = (Get-Content -Path 'C:\StorageReport\Servers.txt' | Where-Object { $_ -match '\S' }).Trim()
$OutFile = Join-Path -Path 'C:\StorageReport' -ChildPath "DiskReport_$LogDate.csv"
# because we now are Appending to the csv, we must make sure we start off with a new file
