我认为在这种情况下，您将需要Write-Output。

如果你有一个脚本

Write-Output "test1";
Write-Host "test2";
"test3";

然后，如果你调用带有重定向输出的脚本，就像你的脚本。Ps1 > out.txt，你将得到屏幕上的test2 test1\ntest3\n在“out.txt”。

请注意，"test3"和Write-Output行总是会在你的文本中追加一个新行，在PowerShell中没有办法停止这一点(也就是说，echo -n在PowerShell的本机命令中是不可能的)。如果你想要echo -n的功能(在Bash中有点基本和简单)，请参阅samthebest的答案。

If a batch file runs a PowerShell command, it will most likely capture the Write-Output command. I have had "long discussions" with system administrators about what should be written to the console and what should not. We have now agreed that the only information if the script executed successfully or died has to be Write-Host'ed, and everything that is the script's author might need to know about the execution (what items were updated, what fields were set, et cetera) goes to Write-Output. This way, when you submit a script to the system administrator, he can easily runthescript.ps1 >someredirectedoutput.txt and see on the screen, if everything is OK. Then send the "someredirectedoutput.txt" back to the developers.

简单地输出一些东西就是PowerShell是一件美丽的事情——也是它最大的优势之一。例如，常见的Hello, World!应用程序简化为一行:

"Hello, World!"

它创建一个字符串对象，分配前面提到的值，作为命令管道上的最后一项，它调用. tostring()方法并将结果输出到STDOUT(默认情况下)。一件美丽的事情。

其他Write-*命令专门用于将文本输出到相关的流中，并具有相应的位置。

Write-Host "Found file - " + $File.FullName -ForegroundColor Magenta

洋红色可以是“系统”之一。ConsoleColor”枚举值-黑色，深蓝色，深绿色，暗青色，暗红色，暗品红，暗黄色，灰色，暗灰色，蓝色，绿色，青色，红色，品红，黄色，白色。

+ $文件。FullName是可选的，它显示了如何将变量放入字符串中。

您根本无法让PowerShell提交这些讨厌的换行符。没有脚本或cmdlet可以做到这一点。

当然Write-Host完全是胡说八道，因为你不能从它重定向/管道!你只需要自己写:

using System;

namespace WriteToStdout
{
    class Program
    {
        static void Main(string[] args)
        {
            if (args != null)
            {
                Console.Write(string.Join(" ", args));
            }
        }
    }
}

E.g.

PS C:\> writetostdout finally I can write to stdout like echo -n
finally I can write to stdout like echo -nPS C:\>

我认为下面是Echo vs. Write-Host的一个很好的展示。请注意test()实际上是如何返回一个整数数组，而不是一个整数，因为人们很容易相信。

function test {
    Write-Host 123
    echo 456 # AKA 'Write-Output'
    return 789
}

$x = test

Write-Host "x of type '$($x.GetType().name)' = $x"

Write-Host "`$x[0] = $($x[0])"
Write-Host "`$x[1] = $($x[1])"

上述终端输出:

123
x of type 'Object[]' = 456 789
$x[0] = 456
$x[1] = 789
