使用 powershell 删除多个应用程序?
我想创建一个脚本来删除一堆应用程序。我希望在启动脚本后无需用户交互即可执行此操作。
这是我到目前为止的脚本;它不起作用,但希望您能看到我正在尝试做的事情:
$App = Get-Content "C:\ListOFApps.txt" #get a list of apps
$args= '/quiet /norestart' # stores arguments for start-process
#gwmi gets the list of applications
# where selects just the apps im interested in removing
# start-process removes each app using msiexec with quiet and norestart options
gwmi win32_product | where { $App -contains $_.Name } | foreach {Start-Process 'msicexec /uninstall ' $_.IdentifyingNumber -ArgumentList $args -wait}'
这是发生的错误:
ForEach-Object : Cannot process command because of one or more missing mandatory parameters: Process.
At C:\Users\username\AppData\Local\Temp\406f96a1-19b4-4e0d-af1b-b1ac2e32a6ba.ps1:3 char:62
+ gwmi win32_product| where { $App -contains $_.Name }| foreach <<<<
+ CategoryInfo : InvalidArgument: (:) [ForEach-Object], ParameterBindingException
+ FullyQualifiedErrorId : MissingMandatoryParameter,Microsoft.PowerShell.Commands.ForEachObjectCommand
$_.IdentifyingNumber
Start-Process 'msicexec /uninstall $_.IdentifyingNumber' -ArgumentList $args -wait
I want to create a script to remove a bunch of apps. I want to do this without user interaction once I've started the script.
This is the script I have so far; it doesn't work but hopefully you can see what I'm trying to do:
$App = Get-Content "C:\ListOFApps.txt" #get a list of apps
$args= '/quiet /norestart' # stores arguments for start-process
#gwmi gets the list of applications
# where selects just the apps im interested in removing
# start-process removes each app using msiexec with quiet and norestart options
gwmi win32_product | where { $App -contains $_.Name } | foreach {Start-Process 'msicexec /uninstall ' $_.IdentifyingNumber -ArgumentList $args -wait}'
This is the error that occurred:
ForEach-Object : Cannot process command because of one or more missing mandatory parameters: Process.

在“foreach”行的末尾有一个不平衡的单引号。我怀疑解决这个问题只是你问题的开始。祝你好运。
You have an unbalanced single quote on the end of the line with the "foreach." I suspect fixing that is only the start of your problems. Good luck.
另外,您的流程拼写错误。应该是“msiexec”而不是“micexec”
Also you have the Process misspelled. Should be "msiexec" not "msicexec"
