Datetime 如何向PowerShell&；的各行添加时间戳；输出？

如果可能的话，如何将时间戳添加到由

&

PowerShell操作符生成的输出的每一行

例如：

PS H:\> $result = & ping 192.168.1.1
PS H:\> echo $result

Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.1: bytes=32 time=104ms TTL=250
Reply from 192.168.1.1: bytes=32 time=106ms TTL=250
Reply from 192.168.1.1: bytes=32 time=102ms TTL=250

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 102ms, Maximum = 106ms, Average = 103ms

预期结果：

PS H:\> echo $result

我知道如何拆分/加入PowerShell阵列，但这只能在

&

操作符完成后发生。我正在寻找更像实时性的解决方案，在&operator运行时将时间戳添加到输出中

---

顺便说一下，时间戳本身是

$（$（Get Date-Format o）+“：”）

您可以使用一个过滤器：

filter timestamp {"$(Get-Date -Format o): $_"}
$result = & ping 192.168.1.1 | timestamp

来自

$result

的示例输出：

2014-12-08T11:42:59.2827202-05:00: 
2014-12-08T11:42:59.2857205-05:00: Pinging 192.168.1.1 with 32 bytes of data:

您可以将Start-Transcript cmdlet与配置文件中的自定义提示结合使用：

# Configure PS prompt to show date and time
function prompt
{ 
    $promptStringStart = "PS:" + (Get-Date -format MM/dd/yy` hh:mm:ss)
    $promptStringEnd += ">"
    Write-Host $promptStringStart -NoNewline -ForegroundColor Yellow
    Write-Host $promptStringEnd -NoNewline -ForegroundColor Yellow
    return " "
}

这在我的Windows7工作站上非常有效。然而，在一些较新的服务器上，2012 R2安装的开始记录似乎有点破损。这修复了其中的一部分：

。。。但它仍然无法解决自定义提示的问题

例如，我在控制台上看到：

PS:02/14/17 08:28:20> hostname
server463

这是写入日志的内容：

PS:02/14/17 08:28:20
>

PS>hostname
server463

对于正在查找有关

过滤器的详细信息的任何人，

。搜索“过滤器”和“powershell”这两个词的任何组合都会给出一百万个示例，而没有任何文档，这让人感到惊讶。此外，powershell中的

帮助过滤器

也没有提供明显的帮助

mjolinor提供的答案是做类似事情的最佳方式，但我想进一步说明

filter timestamp {"$(Get-Date): $_"}

这是打电话的捷径

function timestamp { Process{"$(Get-Date): $_"} }

这两个函数都创建了接受管道输入的命名函数。在powershell中运行帮助行以了解更多信息。管道一次将在单个对象上运行，该对象可以使用

$\uu

引用。因此，每个函数都将使用

|

管道字符迭代管道中的每个项目

这与普通函数的行为不同，因为它在对象到达时处理对象，而不是一次处理所有对象。比如跑步

function timestamp {
        "$(Get-Date): $input"
}
$result = & ping 127.0.0.1
$result | timestamp

将整个

$result

对象转储到一行上，并生成如下所示的响应

我的问题是如何首先将时间戳添加到输出中，而不是如何随后过滤它们，这就是过滤器所做的。PowerShell筛选器是一个脚本块，它接受来自管道的输入，并对从管道获取的每个对象运行一次。它在功能上与只有进程块的函数相同。该过滤器会将时间戳添加到可执行文件的每一行输出中。啊，事实上，它的工作方式与您描述的完全相同。谢谢，问题解决了！谢谢，这是一个非常有趣的方法，我相信它在某些场景中是有用的。我坚持使用时间戳过滤器的方法，尽管根据mjolinor上面的回答。更适合我的需要。这可能是最短的代码，可以让事情顺利完成。我坚持使用mjolinor的解决方案，因为它更适合我（更大的代码库、多个脚本等，所以代码的可重用性对我来说很重要）
