在资源管理器中的选定文件上执行PowerShell命令 [英] Execute PowerShell command on selected files in Explorer

问题描述

如何在PowerShell中仅对资源管理器中的选定文件执行重命名命令?我有PS命令，但是我不知道将它放在Windows注册表中的什么位置，以便在资源管理器的右键单击上下文菜单中可以访问.

How to execute a rename command in PowerShell only on selected files in Explorer? I have the PS command but I don't know where to put it in the Windows registry to be accessible in the right-click context menu in Explorer.

推荐答案

使用Powershell的

It is fairly easy to add a context-menu command to selected files in File Explorer using Powershell's New-Item cmdlet to write a command line to the registry:

# Add a context-menu item named 'Foo' to the context menu of files 
# that executes a PowerShell command that - in this simple demonstration - 
# simply *echoes* the file path given, using Write-Output.
$null = New-Item -Force "HKCU:\Software\Classes\*\shell\Foo\command" | 
        New-ItemProperty -Name '(Default)' -Value `
         "$PSHOME\powershell.exe -NoProfile -NoExit -Command Write-Output \`"%1\`""

^{以上内容针对HKCU:\Software\Classes\*\shell(HKEY_CURRENT_USER\Software\Classes\*\shell)，因此仅适用于文件；仅文件夹位置为HKCU:\Software\Classes\Folder\shell， 文件和文件夹的位置均为HKCU:\Software\Classes\AllFileSystemObjects\shell.
还要注意上面的-LiteralPath的使用，这对于防止将HKCU:\Software\Classes\*中的*解释为通配符至关重要.
请注意，写入等效的HKEY_LOCAL_MACHINE键以使该命令对所有用户可用，将需要 elevation (以管理员身份运行).}

^{The above targets HKCU:\Software\Classes\*\shell (HKEY_CURRENT_USER\Software\Classes\*\shell) and therefore applies to files only; the folder-only location is HKCU:\Software\Classes\Folder\shell, and the location for both files and folders is HKCU:\Software\Classes\AllFileSystemObjects\shell.
Also note the use of -LiteralPath above, which is crucial to prevent interpretation of the * in HKCU:\Software\Classes\* as a wildcard.
Note that writing to the equivalent HKEY_LOCAL_MACHINE keys so as to make the command available to all users would require elevation (running as administrator).}

腔是通过这种方法，对于每个选定文件 ，该命令将被多个文件调用被选中.

The caveat is that with this approach the command is invoked for each selected file, should multiple files be selected.

换句话说:如果您打算重命名文件的组，并且您的重命名逻辑要求将该组视为整体 ，则上述方法将不会工作.

In other words: if your intent is to rename a group of files and your renaming logic requires that the group be considered as a whole, the above approach won't work.

您可以尝试在脚本本身中解决该问题，但这并不容易.

You could try to work around that in the script itself, but that would be nontrivial.

另一种健壮的解决方案是创建上下文菜单处理程序，该方法需要编写正在实现为DLL的进程内组件对象模型(COM)对象 "(来自文档).

A more robust solution is to create context-menu handlers, which requires writing "in-process Component Object Model (COM) objects implemented as DLLs" (from the docs).
