使用 Powershell 替换方括号
如果您有一个文件名，例如“委员会会议纪要 [2010 年 10 月] - hq.doc”，如何让 Powershell 替换方括号？以下不起作用：
ls -filter *`[*`]* | foreach -Process { Rename-Item $_ -NewName ($_.Name -replace '\[', '\(') | Rename-Item $_ -NewName ($_.Name -replace '\]', '\)')}
我收到错误：
Rename-Item : Cannot rename because item at 'Committee minutes [October 2010] - hq.doc' does not exist.
At line:1 char:53
+ ls -filter *`[*`]* | foreach -Process { Rename-Item <<<< $_ -NewName ($_.Name -replace '\['
]', '\)')}
+ CategoryInfo : InvalidOperation: (:) [Rename-Item], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RenameItemCommand
If you have a filename such as "Committee minutes [October 2010] - hq.doc", how do you get Powershell to replace the square brackets? The following doesn't work:
ls -filter *`[*`]* | foreach -Process { Rename-Item $_ -NewName ($_.Name -replace '\[', '\(') | Rename-Item $_ -NewName ($_.Name -replace '\]', '\)')}
I get the error:
Rename-Item : Cannot rename because item at 'Committee minutes [October 2010] - hq.doc' does not exist.
At line:1 char:53
+ ls -filter *`[*`]* | foreach -Process { Rename-Item <<<< $_ -NewName ($_.Name -replace '\['
]', '\)')}
+ CategoryInfo : InvalidOperation: (:) [Rename-Item], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RenameItemCommand

不幸的是，这是 PowerShell 的一个已知错误/限制。一个合适且实际上不错的解决方法是使用
Move-Item重命名项目：它具有-LiteralPath参数，而Rename-Item中缺少该参数>。请参阅报告的问题：

Unfortunately this is a known bug/limitation of PowerShell. A suitable and actually not bad workaround is to use
Move-Itemfor renaming items: it has the-LiteralPathparameter which is missing inRename-Item.See reported issues:
