![尝试让 PowerShell 函数中的第二个参数起作用](https://linux22.com/image/663888/%E5%B0%9D%E8%AF%95%E8%AE%A9%20PowerShell%20%E5%87%BD%E6%95%B0%E4%B8%AD%E7%9A%84%E7%AC%AC%E4%BA%8C%E4%B8%AA%E5%8F%82%E6%95%B0%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
我正在开发一个函数,用于从远程计算机的注册表中提取 DisplayName 和 UninstallStrings。如果我只使用“$software”参数,它在我的本地 PC 上工作正常。但是,如果我添加“$compname”变量并尝试使用调用命令来让远程 PC 执行相同的操作,它会中断。以下是我目前的情况:
Function Get-Uninstallers {
param (
[parameter(mandatory)]
[string]$compName,
[parameter(mandatory)]
[string]$software,
$soft = ('"' + ("*" + $software + "*") + '"')
)
Invoke-Command -ComputerName $compname {
Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall |
Get-ItemProperty | Where-Object {$_.DisplayName -like $soft} |
Select-Object DisplayName, UninstallString
}
}
我尝试了各种不同的 $soft 变量组合,带/不带引号、单引号、不带 * 和不带 *。我知道我做错了什么,但我无论如何也想不通。我尝试在命令行上为参数添加引号,然后又去掉它们。
下面是我填写变量时得到的输出示例:
PS C:\> Invoke-Command -ComputerName 61966 {
Get-ChildItem -Path HKLM: \SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall,
HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall |
Get-ItemProperty | Where-Object {$_.DisplayName -like "*calabrio*"} |
Select-Object DisplayName, UninstallString
}

答案1
我试过你的函数,结果也是空的。问题在于你对软件参数做了什么:你不必将其转换为变量$soft
,你可以直接$software
在 Where-Object 子句中使用带有星号的 -Variable。只需使用:
Get-ItemProperty | Where-Object {$_.DisplayName -like "*$software*"} | Select-Object DisplayName,UninstallString
这在我的系统上运行良好,通配符也运行良好。
编辑:这是在我的计算机上运行的完整函数 - 将变量转换$software
为的行$soft
只是被禁用,因为您不需要它:
Function Get-Uninstallers {
param(
[parameter(mandatory=$true)][string]$compName,
[parameter(mandatory=$true)][string]$software
#$soft = ('"' + ("*" + $software + "*") + '"')
)
Invoke-Command -ComputerName $compname {
Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | `
Get-ItemProperty | Where-Object {$_.DisplayName -like "*$using:software*"} | Select-Object DisplayName,UninstallString
}
}
当我使用该功能时,例如
Get-Uninstallers -compname my-pc -software VMWare
我得到一个包含所有软件的列表,其中 DisplayName 包含“VMware“,仅此而已。
