我在目录Eric Clapton - Nothing But The Blues - Full Concert (1994) [HQ].URL
中有一个名为C:\Hans\Hans4\
的文件。
创建此代码的代码如下(尽管无论文件内容如何都会发生错误)
$fileContents = @"
[{000214A0-0000-0000-C000-000000000046}]
Prop3=19,2
[InternetShortcut]
URL=http://example.com/
IDList=
"@
New-Item -Path "C:\Hans\Hans4" `
-Name "Eric Clapton - Nothing But The Blues - Full Concert (1994) [HQ].URL" `
-ItemType "file" `
-Value $fileContents `
-Force
当我运行以下内容时出现错误
Get-ChildItem 'C:\Hans' -Recurse | Resolve-ShortcutFile > Output.txt
代码引用下面的函数
function Resolve-ShortcutFile {
param(
[Parameter(
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
Position = 0)]
[Alias("FullName")]
[string]$fileName
)
process {
if ($fileName -like "*.url") {
Get-Content $fileName | Where-Object {
$_ -like "url=*"
} |
Select-Object @{
Name='ShortcutFile'
Expression = {Get-Item $fileName}
}, @{
Name='Url'
Expression = {$_.Substring($_.IndexOf("=") + 1 )}
}
}
}
}
这是错误消息
Get-Content : An object at the specified path C:\Hans\Hans4\Eric Clapton - Nothing But The Blues - Full Concert (1994) [HQ].URL does not exist, or has been filtered by the -Include or -Exclude parameter. At line:33 char:28 + Get-Content $fileName | Where-Object { + ~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (System.String[]:String[]) [Get-Content], Exception + FullyQualifiedErrorId : ItemNotFound,Microsoft.PowerShell.Commands.GetContentCommand
为什么我会收到此错误?
答案 0 :(得分:15)
问题是传递给函数并传递给Get-Content
C:\ Hans \ Hans4 \ Eric Clapton - Nothing But The Blues - Full Concert (1994) [HQ] .URL
您遇到了here所描述的问题。
它包含方括号,解释为range operator with the set H and Q
因此该模式意味着它尝试使用以下任一名称来读取文件的内容......
...但与
中的文字[HQ]
不匹配
您可以使用-literalPath
参数来避免此问题,并按字面意思处理文件名。
function Resolve-ShortcutFile {
param(
[Parameter(
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
Position = 0)]
[Alias("FullName")]
[string]$fileName
)
process {
if ($fileName -like "*.url") {
Get-Content -literalPath $fileName | Where-Object {
$_ -like "url=*"
} |
Select-Object @{
Name='ShortcutFile'
Expression = {Get-Item -literalPath $fileName}
}, @{
Name='Url'
Expression = {$_.Substring($_.IndexOf("=") + 1 )}
}
}
}
}
