问题描述

我正在尝试删除输出前后的空白行，但它不起作用.我尝试在第一个Write-Host之后添加-NoNewLine，但是到目前为止只删除了一个空白行.

I'm trying to remove blank lines before and after output but it's just not working. I tried Adding -NoNewLine after the very first Write-Host, but that only removes one blank line so far.

代码:

  $tag1 = "c91638"

    Write-Host "Operating System Information"


    $OSInfo = get-wmiobject -class win32_operatingsystem -computername $tag1

    $OSInfo `
        | Format-List `
            @{Name="OS Name";Expression={$_.Caption}},
            @{Name="OS Boot Time";Expression={$_.ConvertToDateTime($_.LastBootUpTime)}},
            @{Name="OS Install Date";Expression={$_.ConvertToDateTime($_.InstallDate)}};

    Write-Host "Line test.."

输出:

Operating System Information


OS Name         : Microsoft Windows 7 Enterprise
OS Boot Time    : 8/27/2015 2:05:35 AM
OS Install Date : 4/4/2014 11:39:15 AM



Line test..

我想做什么:

Operating System Information

OS Name         : Microsoft Windows 7 Enterprise
OS Boot Time    : 8/27/2015 2:05:35 AM
OS Install Date : 4/4/2014 11:39:15 AM

Line test..

推荐答案

尝试以下方法:

($OSInfo `
    | Format-List `
        @{Name="OS Name";Expression={$_.Caption}},
        @{Name="OS Boot Time";Expression={$_.ConvertToDateTime($_.LastBootUpTime)}},
        @{Name="OS Install Date";Expression={$_.ConvertToDateTime($_.InstallDate)}}  `
    | Out-String).Trim()

这将清除Format-List产生的所有多余的空白行.您可能需要插入一些自己要控制的东西.

That'll clean up all the extraneous blank lines produced by Format-List. You may need to insert a couple of your own that you get to control.
