Question

我正在创建一个脚本，以便从文本文件中读取一组PC的正常运行时间/最后一次重启。

我可以将结果输出到文件，但它会不断重复我不想要的列标题。基本上我想要的是输出标题的第一行，然后输出数据后面的数据。下面的代码将列标题重复到输出文件，并且行之间有很多空格。输出到CSV会更容易处理吗？

这是我的代码。第一个Out-File命令用于覆盖文件（如果存在），实际上是清除文件。

$computers = Get-Content "c:\temp\ps\pc.txt"

out-file -FilePath "C:\temp\ps\output.txt"
foreach ($computer in $computers) 
{
    $Computerobj = "" | select ComputerName, Uptime, LastReboot
    $wmi = Get-WmiObject -ComputerName $computer -Query "SELECT LastBootUpTime     FROM Win32_OperatingSystem"
    $now = Get-Date
    $boottime = $wmi.ConvertToDateTime($wmi.LastBootUpTime)
    $uptime = $now - $boottime
    $d =$uptime.days
    $h =$uptime.hours
    $m =$uptime.Minutes
    $s = $uptime.Seconds
    $Computerobj.ComputerName = $computer
    $Computerobj.Uptime = "$d Days $h Hours $m Min $s Sec"
    $Computerobj.LastReboot = $boottime
    $Computerobj
    out-file -FilePath "C:\temp\ps\output.txt" -in $computerobj -append
}

Answer 1

使用<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="fill" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.joker.charsoo.Main" > <view android:id="@+id/view1" android:layout_width="match_parent" android:layout_height="match_parent" class="ScrollView" /> <LinearLayout android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_centerHorizontal="true" android:orientation="vertical" > <ImageView android:id="@+id/main" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="117dp" android:layout_marginTop="88dp" android:src="@drawable/ic_launcher" /> </LinearLayout>和ForEach-Object的管道是更好的方法：

Export-Csv

如果您需要文件和控制台上的数据，可以使用$now = Get-Date Get-Content -Path 'C:\temp\ps\pc.txt' | ForEach-Object { $wmi = Get-WmiObject -ComputerName $_ -Class Win32_OperatingSystem $boottime = $wmi.ConvertToDateTime($wmi.LastBootUpTime) $uptime = $now - $boottime New-Object -Type PSObject -Property @{ 'ComputerName' = $_ 'Uptime' = '{0} Days {1} Hours {2} Min {3} Sec' -f $uptime.Days, $uptime.Hours, $uptime.Minutes, $uptime.Seconds 'LastReboot' = $boottime } } | Export-Csv -Path 'C:\temp\ps\output.txt' -NoType和ConvertTo-Csv：

Tee-Object

Answer 2

试试这个：

$computers = Get-Content "c:\temp\ps\pc.txt"

#Create a report variable as an array to hold all our data
$report = @();

#No longer necessary
#out-file -FilePath "C:\temp\ps\output.txt"

foreach ($computer in $computers) 
{
    $Computerobj = "" | select ComputerName, Uptime, LastReboot
    $wmi = Get-WmiObject -ComputerName $computer -Query "SELECT LastBootUpTime     FROM Win32_OperatingSystem"
    $now = Get-Date
    $boottime = $wmi.ConvertToDateTime($wmi.LastBootUpTime)
    $uptime = $now - $boottime
    $d =$uptime.days
    $h =$uptime.hours
    $m =$uptime.Minutes
    $s = $uptime.Seconds
    $Computerobj.ComputerName = $computer
    $Computerobj.Uptime = "$d Days $h Hours $m Min $s Sec"
    $Computerobj.LastReboot = $boottime

    #Add the computer to the report array
    $report += $Computerobj
}

#Uncomment this if you need to see the report as well as write it to a file
#Write-Output $report

out-file -FilePath "C:\temp\ps\output.txt" -in $report

现在，您可以整体处理报告，因此您甚至可以在最后添加内容，例如$report = $report | Sort-Object -Property ComputerName，以便按计算机名称对报告进行排序，或者使用Where-Object过滤报告。
