PowerShell的 - 响应命令响应 [英] PowerShell - Respond to a Command response

问题描述

我试图写一个简单的脚本，将执行在Windows控制台命令，它会一直询问覆盖现有数据的确认。我觉得下面有点像会的工作，但现在看来我错了（没有惊喜，写主机不使用命令行交互，我相信这只是把文字在屏幕上）。任何人都可以提供关于如何处理这一一些建议吗？我需要能够执行没有任何交互每周通过任务调度的脚本。

脚本：

 开始处理-NoNewWindow -FilePath PW -ArgumentList @
    门槛检查站打造WeeklyBackupWeeklyBackup
@
睡眠-Seconds 3
$确认=选择字符串-pattern关于过度写现有的CheckPoint'WeeklyBackup'。 -安静如果（$确认）
{
   写主机Y`r
}
 

我希望在控制台中看到：

  D：\\ BMC_Software \\ ProactiveNet＆GT; PW门槛检查站打造WeeklyBackup周
lyBackup
即将覆写现存的CheckPoint'WeeklyBackup。你想继续吗？
（Y / N）
 

然后，用户将达到Y和回车和过程将完成。但我想这个自动的。

在此先感谢您的任何建议。

解决方案

 回声Y`r| PW
 

这通常是从批处理文件中使用，但通常效果一样好，从PowerShell中。

I am trying to write a simple script that will execute a console command in Windows, which will always ask for a confirmation for overwriting the existing data. I thought something like the below would work, but it appears I was mistaken (and no surprise, write-host doesn't interact with the command line, I believe it simply puts text on screen). Can anyone provide some advice on how to handle this? I need to be able to execute the script through task scheduler on a weekly basis with no interaction.

Script:

Start-Process -NoNewWindow -FilePath pw -ArgumentList @"
    threshold checkpoint create "WeeklyBackup" "WeeklyBackup"
"@
sleep -Seconds 3
$confirm = Select-String -pattern "About to over-write existing CheckPoint 'WeeklyBackup'." -Quiet

if ($confirm)
{
   Write-Host "Y`r" 
}

What I expect to see in the console:

D:\BMC_Software\ProactiveNet>pw threshold checkpoint create "WeeklyBackup" "Week
lyBackup"
About to over-write existing CheckPoint 'WeeklyBackup'. Do you want to proceed?
(y/n)

Then a user would hit Y and carriage-return and the process would be done. But I want this automated.

Thanks in advance for any advice.

解决方案

echo "Y`r" | pw

This is typically used from batch files but it usually works just as well from PowerShell.
