隐藏写入主机输出 [英] Hide Write-Host outputs

问题描述

我正在编辑一个需要转换为 exe 的脚本.它有几个 Write-Host 输出脚本运行时的状态.这会导致脚本的 exe 向用户显示对话框，迫使他们在脚本完成之前单击 3 或 4 次.

I am editing a script which I need to convert to exe. It has a few Write-Host outputs of the status of the script when running. This causing the exe of the script to show up dialog boxes to the user forcing them to click OK 3 or 4 times before the script finishes.

我想保留 Write-Host 输出但只是在最终用户从 exe 执行它时隐藏它们(对话框).

I'd like to keep the Write-Host output but just hide them (the dialog boxes) when the end user executes it from the exe.

这可能吗?我查看了代码不喜欢的 [void] .我可以开始工作的唯一其他方法就是用 # 注释掉它，但我相信有更好的方法.

Is this possible? I have looked into [void] which the code doesn't like. The only other way I can get to work is just commenting it out with #, but I'm sure there's a better way.

我想要隐藏/抑制的示例:

Example of what I want hidden/suppressed:

Write-Host "Current Status = " $status

推荐答案

根据评论你应该使用 Write-Verbose 而不是 Write-Host 因为这会给你只需很少的努力即可获得您想要的功能.但是，要使用 Write-Verbose，您还需要进行一些其他更改:

Per the comments you should use Write-Verbose instead of Write-Host as this will give you the functionality you want with very little effort. However to use Write-Verbose there's a couple of other changes you'll need to make:

首先，您需要将其添加到脚本的顶部:

First you'll need to add this to the top of your script:

 [cmdletbinding()]
 Param()

这为您的脚本提供了一组默认参数，其中一个包括 -Verbose，它可以在使用时显示任何 Write-Verbose 消息.

This gives your script a set of default parameters one of which includes -Verbose which enables any Write-Verbose messages to be displayed when used.

其次(基于您提供的示例)您可能需要稍微重写一些(现在)Write-Verbose 字符串语句.例如:

Secondly (based on the example you gave) you might need to slightly rewrite some of your (now) Write-Verbose string statements. For example:

write-host "Current Status = " $status

与 Write-Host 一起使用，因为它需要一个字符串数组作为输入.Write-Verbose 不一样，它只需要一个字符串，所以上面的例子需要改为:

Works with Write-Host because it takes an array of strings as input. The same is not true of Write-Verbose, it only takes a single string, so the above example would need to be changed to:

Write-Verbose "Current Status =  $status"

请注意，通过使用双引号字符串，变量仍将被扩展.

Note that by using double quote strings the variable will still be expanded.
