powershell - Powershell获取服务-forgroundcolor

Question

我正在尝试更改get-service输出的颜色。它似乎不允许我在get-service之后使用write-host -forgroundcolor参数。有没有办法解决？

我尝试了以下配置:

get-service write-host -foregroundcolor "green"
get-service -foregroundcolor "green"

如果将get-service保存到一个变量中，然后将write-host放在前面，就可以使它正常工作:

$var = get-service

write-host $var -foregroundcolor "green"

问题是输出格式不正确，变成一行。

Answer 1

Get-Service | Out-String [-Stream] | Write-Host -ForegroundColor Green

根据 Out-String的帮助主题:

The Out-String cmdlet converts the objects that Windows PowerShell manages into an
array of strings. By default, Out-String accumulates the strings and returns them as
a single string, but you can use the stream parameter to direct Out-String to return 
one string at a time. This cmdlet lets you search and manipulate string output as 
you would in traditional shells when object manipulation is less convenient.

通过使用 -Stream参数，您无需等待 Get-Service完成执行，但它会在获取输入时接受输入。
