如何调试“术语”X“不被识别为cmdlet，函数，脚本文件或可操作程序的名称”？

Question

代码：

G$Folders = Get-childItem C:\permissiontest\ 
$InheritanceFlag = [System.Security.AccessControl.InheritanceFlags]::ContainerInherit -bor [System.Security.AccessControl.InheritanceFlags]::ObjectInherit 
$PropagationFlag = [System.Security.AccessControl.PropagationFlags]::InheritOnly 
$objType = [System.Security.AccessControl.AccessControlType]::Allow 

foreach ($TempFolder in $Folders) 
{ 
echo "Loop Iteration" 
$Folder = $TempFolder.FullName 

$acl = Get-Acl $Folder 
$permission = "MRGROUP\ro","Read", $InheritanceFlag, $PropagationFlag, $objType 
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission 

$acl.SetAccessRule($accessRule) 
Set-Acl $Folder $acl 
} 

错误：

G$Folders : The term 'G$Folders' is not recognized as the name of a cmdlet, function, script file, or 
operable program. Check the spelling of the name, or if a path was included, verify that the path is correct 
and try again. 
At C:\script\aclper.ps1:1 char:1 
+ G$Folders = Get-childItem C:\permissiontest\ 
+ ~~~~~~~~~ 
    + CategoryInfo   : ObjectNotFound: (G$Folders:String) [], CommandNotFoundException 
    + FullyQualifiedErrorId : CommandNotFoundException 

Answer 1

替换：

G$Folders = Get-childItem C:\permissiontest\ 

有：

$Folders = Get-childItem C:\permissiontest\ 

这将摆脱这种错误
