Question

我是PowerShell的新手。现在的任务是将某些程序固定到任务栏。这个Tutorial很棒，并且在我的一个Win7 32位Vmware中运行良好。但是同样的脚本无法在Vmware的Win10 32bit中运行。所以我修改了代码，最后发现它是因为找不到一些动词。我的测试代码如下：

CLS
$cmd = 'C:\Windows\System32\cmd.exe'
Test-Path $cmd
$Shell = New-Object -ComObject Shell.Application
$Desktop = $Shell.NameSpace(0X0)
$itemLnk = $Desktop.ParseName($cmd)
$itemVerbs = $itemLnk.Verbs()
Foreach($v in $itemVerbs)
{
    write-host $v.Name
}

ISE以管理员身份运行，结果以及通过右键单击cmd.exe找到的“动词”如下所示：

所以请告诉我为什么以及如何解决这个问题，谢谢！

Answer 1

可能是因为cmd.exe中没有C:\Windows\，请改用：

$cmd = Join-Path $env:SystemRoot 'System32\cmd.exe'

注意：我使用Join-Path cmdlet组合路径和$env:SystemRoot来检索系统根目录（例如C:\Windows）

您只能在第一个分隔符和属性上方使用动词。您的程序必须继续运行才能显示属性。

这是一个列出并执行动词的VBScript。 ShVerb.vbs /?阅读上述内容。

HelpMsg = vbcrlf & "  ShVerb" & vbcrlf & vbcrlf & "  2014" & vbcrlf & vbcrlf & "  Lists or runs an explorer verb (right click menu) on a file or folder" & vbcrlf  & vbcrlf & "    ShVerb <filename> [verb]" & vbcrlf & vbcrlf & "  Used without a verb it lists the verbs available for the file or folder" & vbcrlf & vbcrlf
HelpMsg = HelpMsg & "  The program lists most verbs but only ones above the first separator" & vbcrlf & "  of the menu work when used this way" & vbcrlf & vbcrlf 
HelpMsg = HelpMsg & "  The Properties verb can be used. However the program has to keep running" & vbcrlf & "  to hold the properties dialog open. It keeps running by displaying" & vbcrlf & "  a message box." 
Set objShell = CreateObject("Shell.Application")
Set Ag = WScript.Arguments 
set WshShell = WScript.CreateObject("WScript.Shell") 
Set fso = CreateObject("Scripting.FileSystemObject")

    If Ag.count = 0 then 
        wscript.echo "  ShVerb - No file specified"
        wscript.echo HelpMsg 
        wscript.quit
    Else If Ag.count = 1 then 
        If LCase(Replace(Ag(0),"-", "/")) = "/h" or Replace(Ag(0),"-", "/") = "/?" then 
            wscript.echo HelpMsg 
            wscript.quit
        End If
    ElseIf Ag.count > 2 then 
        wscript.echo vbcrlf & "  ShVerb - To many parameters" & vbcrlf & "  Use quotes around filenames and verbs containing spaces"  & vbcrlf
        wscript.echo HelpMsg 
        wscript.quit
    End If

    If fso.DriveExists(Ag(0)) = True then
        Set objFolder = objShell.Namespace(fso.GetFileName(Ag(0)))
'       Set objFolderItem = objFolder.ParseName(fso.GetFileName(Ag(0)))
        Set objFolderItem = objFolder.self
        msgbox ag(0)
    ElseIf fso.FolderExists(Ag(0)) = True then
        Set objFolder = objShell.Namespace(fso.GetParentFolderName(Ag(0)))
        Set objFolderItem = objFolder.ParseName(fso.GetFileName(Ag(0)))
    ElseIf fso.fileExists(Ag(0)) = True then
        Set objFolder = objShell.Namespace(fso.GetParentFolderName(Ag(0)))
        Set objFolderItem = objFolder.ParseName(fso.GetFileName(Ag(0)))
    Else
        wscript.echo "  ShVerb - " & Ag(0) & " not found"
        wscript.echo HelpMsg 
        wscript.quit
    End If

    Set objVerbs = objFolderItem.Verbs

    'If only one argument list verbs for that item

    If Ag.count = 1 then
        For Each cmd in objFolderItem.Verbs
            If len(cmd) <> 0 then CmdList = CmdList & vbcrlf & replace(cmd.name, "&", "") 
        Next
        wscript.echo mid(CmdList, 2)

    'If two arguments do verbs for that item

    ElseIf Ag.count = 2 then
        For Each cmd in objFolderItem.Verbs
            If lcase(replace(cmd, "&", "")) = LCase(Ag(1)) then 
                wscript.echo(Cmd.doit)
                Exit For
            End If
        Next
    'Properties is special cased. Script has to stay running for Properties dialog to show.
        If Lcase(Ag(1)) = "properties" then
            WSHShell.AppActivate(ObjFolderItem.Name & " Properties")
            msgbox "This message box has to stay open to keep the " & ObjFolderItem.Name & " Properties dialog open."
        End If  
    End If
End If

PowerShell找不到一些可执行的动词
