You shoul have a look to <a href="http://technet.microsoft.com/en-us/library/dd315326.aspx" rel="noreferrer">Advanced Functions</a> : With Advanced functions you can take advantage of the common -verbose parameter. Simply output your verbose output this way:

<pre><code>Write-Verbose "Text of debug"
</code></pre>

And when the shell's $VerbosePreference variable isn't set to "SilentlyContinue" ("Continue" will enable the output), you'll see your verbose output.

blocks|key|3134448|text|为了使用Verbose开关，您需要在脚本中指定CmdletBinding属性。要添加对Confirm和WhatIf开关的支持，请添加SupportsShouldProcess属性并在脚本中调用ShouldProcess方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3134449|##+content+of+.\ex01.ps1+##
[CmdletBinding(SupportsShouldProcess=$true)]
Param()
Write-Host+"line+1"

Write-Host+"line+3"

if($PSCmdlet.ShouldProcess($env:COMPUTERNAME,'Remove+X'))

In order to have the Verbose switch you need to specify the CmdletBinding attribute in your script. To add support for the Confirm and WhatIf switches, add the SupportsShouldProcess attribute and call the ShouldProcess method in the script:

<pre><code>## content of .\ex01.ps1 ##
[CmdletBinding(SupportsShouldProcess=$true)]
Param()
Write-Host "line 1"
Write-Verbose "line 2"
Write-Host "line 3"

if($PSCmdlet.ShouldProcess($env:COMPUTERNAME,'Remove X'))
{
 "do something"
}

PS &gt; .\ex01.ps1 -Verbose

i'm a powershell beginner but this just tripped me up:

if your script doesn't have any parameters the verbose switch won't be passed through. just put this at the top of your script:

<pre><code>[CmdletBinding()]
Param()
</code></pre>

so your script would be:

<pre><code>[CmdletBinding()]
Param()
Write-Host "line 1"
Write-Verbose "line 2"
Write-Host "line 3"
</code></pre>

I'm creating a .ps1 script which invokes <code>Write-Verbose</code>. I would like to be able to enable/disable these.

I was hoping that I could pass the <code>-Verbose</code> flag when invoking the script and everything would just work. Unfortunately this doesn't seem to be the case.

The verbose messages are not written out to the host. I looked around a bit and found <a href="http://blogs.msdn.com/b/powershell/archive/2007/02/25/supporting-whatif-confirm-verbose-in-scripts.aspx" rel="nofollow noreferrer">Supporting -Whatif, -Confirm, -Verbose – In SCRIPTS!</a>

But this is from 2007 and the PS team member stated that they were looking for built in support in PS v2.

Anybody have any updates on this or do we have to use the same technique described in that blog post?

Here is an example of the current behavior.

I created a simple script,ex01.ps1, with the following.

<pre><code>Write-Host "line 1"
Write-Verbose "line 2"
Write-Host "line 3"
</code></pre>

I first executed the script with <code>.\ex01.ps1</code>, and only 1 &amp; 2 were printed as expected. Then I executed it with <code>.\ex01.ps1 -verbose</code>, and got the same result. I was expecting all 3 lines to be printed the second time.

我正在创建一个调用Write-Verbose的.ps1脚本。我希望能够启用/禁用这些功能。我希望我可以在调用脚本时传递-Verbose标志，一切都会正常工作。不幸的是，情况似乎并非如此。详细消息不会写出到主机。我环顾了一下，发现了但这是在2007年，PS团队成员表示，他们正在寻找PS v2的内置支持。有人对此有任何更新...
