日志文件输出未捕获所有数据

Question

适用于 Powershell v2

我有以下代码（它只是我一直在处理的大量代码的一部分）。整个事情都有写主机，我被要求看看我是否可以把它放到一个日志文件中。使用此链接，我已按照步骤操作并尝试了许多其他操作，但我无法使所有输出正常工作：

Create Log File in Powershell

很多东西都没有出现在日志文件中 - 它在日志文件中只是空白，但在屏幕上显示了输出 - 即：

1. 任何 WMI 调用输出 - 即

   @(Get-WmiObject -Class Win32_OperatingSystem | 选择标题， BuildNumber、CountryCode、CSDVersion、CSName、InstallDate、 @{Name=”可用物理内存”;Expression={“{0:N1}GB” -f($.FreePhysicalMemory/1mb)}}, @{Name=”分页文件中的可用空间”;Expression={“{0:N1}GB” -f($.FreeSpaceInPagingFiles/1mb )}}, @{Name=”可用虚拟内存”;Expression={“{0:N1}GB” -f($_.FreeVirtualMemory/1mb)}} |格式列表）

2. 刚刚运行的任何命令：即net localgroup administrators

还有更多，但似乎大部分都是 WMI 调用。

这是有问题的代码部分：

网络部分：

$forward = nslookup $computername


$reverse = [System.Net.Dns]::GetHostByName($computername) | select -Expa AddressList | select -Expa ipaddresstostring | % { nslookup $_ }

LogWrite "Doing forward lookup: "
$forward
LogWrite `r`n
LogWrite "Doing reverse lookup: "
$reverse

#$computername = gc env:computername
#$serverName = SV180515

WMI 位：

Answer 1

run powershell.exe -file script.ps1 *> c:\log.txt 这应该在日志文件中写入所有输出和错误

您也可以使用 start-transcript ：

start-transcript -path c:\temp\mylog.txt
.\myscript.ps1
stop-transcript

Answer 2

您是否考虑过在函数中收集脚本？然后您可以使用Out-File -Append 运行脚本中的函数来记录它。将 Write-Host 替换为 Write-Output，因为 write-host 是交互式 cmdlet。然后在你的运行命令中提供 logpath。这是一个示例：

Untitled2.ps1

param($logpath)

function test {
$service = Get-Service | where {$_.status -eq "Running" } 
$service | ft name, status -auto
Write-output "hey"
ping 10.0.0.1

net localgroup
}

if($logpath) {
    #Run functions in script
    test | Out-File -Append $logpath
} else {
    #Run functions in script
    test
}

然后我在 cmd/bat 中使用以下命令运行它：

powershell.exe -noprofile -file Untitled2.ps1 -logpath "c:\users\graimer\desktop\testlog.txt"

或者在powershell中：

.\Untitled2.ps1 -logpath "c:\users\graimer\desktop\testlog.txt"

另一个答案可能是在脚本执行后捕获缓冲区内容。看这里：http://blogs.msdn.com/b/powershell/archive/2009/01/10/capture-console-screen.aspx
