相当于bash的“期望”在 powershell 中

发布于 2024-12-10 04:03:36 字数 144 浏览 1 评论 0原文

我正在使用 powershell 运行另一个 powershell 脚本，在某些时候另一个脚本要求一些输入，我希望能够读取另一个脚本的输出并基于向其提供的输入。类似于您可以在 bash 上使用 Expect 执行的操作。

有什么想法吗？

谢谢

只是发布我的解决方案，以便它可以帮助别人。我在运行其他一些需要答案的脚本时遇到了同样的问题。首先创建一个文件“inputFileLocation.txt”，其中每行中按顺序包含每个问题的答案。然后按以下语法运行脚本。它会完成工作。

`cmd.exe /c "script.bat < inputFileLocation.txt"`

Just posting my solution so that it can help someone. I faced the same problem while running some other script that will ask for answers. First create a file "inputFileLocation.txt" with answers to each question in each line in sequence. Then run the script in below syntax. And it will do the work.

`cmd.exe /c "script.bat < inputFileLocation.txt"`

解决部分问题的示例

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
Start-Process -FilePath C:\myexecbatchfile.bat

# Wait the application start for 2 sec 
Start-Sleep -m 2000

# Send keys
[System.Windows.Forms.SendKeys]::SendWait("input1")
[System.Windows.Forms.SendKeys]::SendWait("{ENTER}")
Start-Sleep -m 3000

[System.Windows.Forms.SendKeys]::SendWait("input2")
[System.Windows.Forms.SendKeys]::SendWait("{ENTER}")

Sample to solve part of the problem

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
Start-Process -FilePath C:\myexecbatchfile.bat

# Wait the application start for 2 sec 
Start-Sleep -m 2000

# Send keys
[System.Windows.Forms.SendKeys]::SendWait("input1")
[System.Windows.Forms.SendKeys]::SendWait("{ENTER}")
Start-Sleep -m 3000

[System.Windows.Forms.SendKeys]::SendWait("input2")
[System.Windows.Forms.SendKeys]::SendWait("{ENTER}")

您只需在 powershell 中使用 Expect 程序即可。有用。 Powershell也是一个shell，你可以运行powershell编写的代码，它调用bash代码，bash代码再次调用powershell。

贝娄是一个测试，它通过了。

It "can work with tcl expect" {
    $bs = @'
    echo "Do you wish to install this program?"
    select yn in "Yes" "No"; do
    case $yn in
        Yes ) echo "install"; break;;
        No ) exit;;
    esac
done
'@

$bsf = New-TemporaryFile
$bs | Set-Content -Path $bsf

$tcls = @'
#!/bin/sh
# exp.tcl \
exec tclsh "$0" ${1+"$@"}

package require Expect
set timeout 100000
spawn {spawn-command}
expect {
    "Enter password: $" {
        exp_send "$password\r"
        exp_continue
    }
    "#\? $" {
            exp_send "1"
    }
    eof {}
    timeout {}
}
'@

$tclf = New-TemporaryFile
$tcls -replace "{spawn-command}",("bash",$bsf -join " ") | Set-Content -Path $tclf
"bash", $tclf -join " " | Invoke-Expression

Remove-Item $bsf
Remove-Item $tclf
}

让我解释一下测试。

创建一个需要输入的 bash 文件。
创建一个 tcl 文件，该文件调用在第一步中创建的 bash。
从powershell调用tcl程序，它可以工作，不会等待输入。

You just use Expect program in your powershell. It works. Powershell is a shell too, you can run code wrote by powershell, which call bash code, which call powershell again.

Bellow is a test, it passed.

It "can work with tcl expect" {
    $bs = @'
    echo "Do you wish to install this program?"
    select yn in "Yes" "No"; do
    case $yn in
        Yes ) echo "install"; break;;
        No ) exit;;
    esac
done
'@

$bsf = New-TemporaryFile
$bs | Set-Content -Path $bsf

$tcls = @'
#!/bin/sh
# exp.tcl \
exec tclsh "$0" ${1+"$@"}

package require Expect
set timeout 100000
spawn {spawn-command}
expect {
    "Enter password: $" {
        exp_send "$password\r"
        exp_continue
    }
    "#\? $" {
            exp_send "1"
    }
    eof {}
    timeout {}
}
'@

$tclf = New-TemporaryFile
$tcls -replace "{spawn-command}",("bash",$bsf -join " ") | Set-Content -Path $tclf
"bash", $tclf -join " " | Invoke-Expression

Remove-Item $bsf
Remove-Item $tclf
}

Let me explain the test.
