输出

期望的输出

Answer 1

"`r`n"

我相信需要双引号。

Answer 2

使用[System.Environment]::NewLine在您需要的任何地方添加新行。

说过为了清晰起见我格式化了代码并针对数组执行了

@("MECDEVAPP01","MECDEVAPP01")| % {
    $Comp = $_
    #write-output "server Information"
    If (Test-Connection $Comp -Quiet){
        $Luser = (Get-WmiObject -class win32_process -Filter "Name='Explorer.exe'" -ComputerName $Comp | % {$_.GetOwner().User} | Sort-Object -Unique) -join ","
        $Mem = GWMI -Class win32_operatingsystem -computername $COMP
        New-Object PSObject -Property @{
            "ServerInfo" = ""
            Server = $Comp
            "CPU usage" = "$((GWMI -ComputerName $COMP win32_processor | Measure-Object -property LoadPercentage -Average).Average) %"
            "Memory usage" = "$("{0:N2}" -f ((($Mem.TotalVisibleMemorySize - $Mem.FreePhysicalMemory)*100)/ $Mem.TotalVisibleMemorySize)) %"
            "Total FreeSpace" = "$("{0:N2}" -f ((Get-WmiObject -Class win32_logicaldisk -ComputerName $COMP -Filter "DriveType = '3'" | Measure-Object -property FreeSpace -Sum).Sum /1GB)) GB"
            "DiskSpace" = "$("{0:N2}" -f ((Get-WmiObject -Class win32_logicaldisk -ComputerName $COMP -Filter "DriveType = '3'" | Measure-Object -property Size -Sum).Sum /1GB)) GB"
            "Comment" =  ""
        "logged Users" = $Luser
      }
    }
    Else{
        "" | Select @{N="Server";E={$Comp}},"CPU usage","Memory usage","Total FreeSpace","logged Users","DiskSpace"
    }
}| Select "ServerInfo",Server,"logged Users","CPU usage","Memory usage","Total FreeSpace" ,"DiskSpace", "Comment"|
Export-Csv "C:\Users\asarafian\Downloads\Diskncpu.csv" -nti –Append

csv文件就像这样

"ServerInfo","Server","logged Users","CPU usage","Memory usage","Total FreeSpace","DiskSpace","Comment"
"","MECDEVAPP01","","7 %","70,24 %","203,97 GB","278,36 GB",""
"","MECDEVAPP01","","0 %","70,25 %","203,97 GB","278,36 GB",""

这是我对将记录集（即您使用所有这些管道构建的内容）转换为csv所期望的内容。

我想生成格式化文本然后你不能使用csv，或者你需要组合它的元素。

Answer 3

尝试使用`r`n换行。它需要新线和回车才能工作。

Answer 4

如果我理解正确的话，您希望一行显示一个换行符，但您得到的是 `r`n 字面字符或任何您试图抛出的字符。

我能想出的最小测试用例来重现这个问题：

> function paste ($separator = '`r`n') {$($input) -join $separator}
> & { echo foo; echo bar; echo baz; } | paste
foo`r`nbar`r`nbaz

预期的结果是

foo
bar
baz

你如何获得实际的换行符作为输出而不是文字`r`n？超级简单，使用建议的答案即可！

> function paste ($separator = "`r`n") {$($input) -join $separator}
> & { echo foo; echo bar; echo baz; } | paste
foo
bar
baz

或者，如果你不喜欢魔法字符串：

function paste ($separator = [System.Environment]::NewLine) {$($input) -join $separator}
PS D:\Temp\specs\ProRail.TrackChanges.Specs.Features> & { echo foo; echo bar; echo baz; } | paste
foo
bar
baz
