鑒于...
HKLM\Software\
KeyName

Property_2
Property_[0-1]
Key*Name

Property_2
Property_[0-1]
Key@Name
Property_1
Property_2
Property_[0-1]
我可以用
Get-Item -path:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name"
這將回傳KeyName,Key*Name和Key@Name, 而
Get-Item -literalPath:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name"
只會回傳Key*Name。到現在為止還挺好。我可以根據需要使用 -path 或 -literalPath 來搜索帶通配符或不帶通配符的鍵。但是屬性帶來了問題。
Get-ItemProperty -path:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\KeyName" -name:"Prop_[0-9]"
按預期作業并從密鑰回傳Prop_1& 。和Prop_2KeyName
Get-ItemProperty -literalPath:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\KeyName" -name:"Prop_[0-9]"
按預期作業并且僅從Prop_[0-9]相同的鍵回傳。但是，當您需要使用通配符在包含通配符作為鍵路徑中的文字的路徑中查找屬性時，這一切都會失敗。所以...
Get-ItemProperty -path:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name" -name:"Prop_[0-9]"
從所有三個鍵回傳Prop_1& Prop_2。根本不是想要的行為。
我曾希望能夠過濾PSPath使用 -`literalPath' 但這
Get-ItemProperty -literalPath:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name" -name:"Prop_[0-9]" | where {$_.PSPath -match [RegEx]::Escape("Key*Name")}
does not return the correct properties. It seems that a -literalPath means a literal name also. So I tried filtering on PSPath and Name like so
Get-ItemProperty -literalPath:"Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name" -name:"Prop_[0-9]" | where {(($_.PSPath -match [RegEx]::Escape("Key*Name")) -and ($_.Name -match "Prop_[0-9]"))}
But that doesn't work because once you actually get real properties, they are no longer a .NET type, they have been shat into a PSCustomObject.
And that is starting to get so complicated I wonder if there is a better way to proceed. I should note that the ultimate goal here is to get both a literal path and a list of literal property names, so that I can move, copy or delete the properties. So, given a path of Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name and a name of Prop_[0-9] I will eventually want to, for example, delete
HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name\Prop_1
&
HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name\Prop_2
but not
HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name\Prop_[0-9]
EDIT: Based on the answer from @Tomalak I have simplified a bit, to simply get back a list of property names. That looks like this
$keyPath = "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name"
$propExpr = "Prop_[0-9]"
((Get-Item -literalPath:$keyPath | Get-ItemProperty).PSObject.Properties | Where-Object Name -Match $propExpr | ForEach-Object {$_.Name})
uj5u.com熱心網友回復：
這將通過文字路徑獲取注冊表項并通過正則運算式匹配過濾其屬性
$keyPath = "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Key*Name"
$propExpr = "Prop_[0-9]"
Get-Item -literalPath $keyPath -PipelineVariable key | Get-ItemProperty | ForEach-Object {
$_.PSObject.Properties | Where-Object Name -Match $propExpr | ForEach-Object {
[pscustomobject]@{
key = $key.Name
prop = $_.Name
value = $_.Value
}
}
}
如果這對您的任務更方便，您$key.Name當然可以回傳實際值而不是$key。
