Get-Item

Get a file/registry object (or any other namespace object)

Syntax
      Get-Item { [-path] string[] | [-literalPath] string[] }
         [-include string[]] [-exclude string[]]
            [-filter string] [-force] [-credential PSCredential] 
               [-UseTransaction] [CommonParameters]

Key
   -path string
       The path(s) to the items. Wildcards are permitted.
       Use a dot (.) to specify the current location. 
       Use the wildcard (*) to specify all items in the current location.

   -literalPath string
       Like Path above, only the value is used exactly as typed.
       No characters are interpreted as wildcards. If the path includes any
       escape characters then enclose the path in single quotation marks.

   -include string
       Include only the specified items from the Path. e.g. "May*"
       this only works when the path includes a wildcard character.

   -exclude string
       Omit the specified items from the Path e.g. "*SS64*"
       this only works when the path includes a wildcard character.

   -filter string
       A filter in the provider's format or language. 
       The exact syntax of the filter (wildcard support etc) depends on the provider.
       Filters are more efficient than -include/-exclude, because the provider
       applies the filter when retrieving the objects, rather than having 
       PowerShell filter the objects after they are retrieved.

   -force
       Override restrictions that prevent the command from succeeding, apart
       from security settings. e.g. Force will create file path directories 
       or override a files read-only attribute, but will not change file permissions.

   -credential PSCredential
       Use a credential to validate access to the file. Credential represents
       a user-name, such as "User01" or "Domain01\User01", or a PSCredential
       object, such as the one retrieved by using the Get-Credential cmdlet.
       If you type a user name, you will be prompted for a password.
       This parameter is not supported by any PowerShell core cmdlets or providers.
 
   -UseTransaction
       Include the command in the active transaction.

   CommonParameters:
       -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable,
       -OutBuffer -OutVariable.

Examples

Get the current directory. This represents the item at the current location (not its contents).
PS C:\>get-item .

Get the root directory of the C: drive. This represents only the directory, not its contents:
PS C:\>get-item C:\

Get all items in the current directory. :
PS C:\>get-item *

Get all items in the C: drive:
PS C:\>get-item C:\*

List all properties of C:\Windows:
PS C:\>(Get-Item C:\Windows) | Get-Member"

Get the LastAccessTime property of C:\Windows:
PS C:\>(get-item C:\Windows).LastAccessTime

Get a registry key.:
PS C:\>get-item hklm:\software\microsoft\exchange

Get-Item will get registry keys and subkeys, but you must use Get-ItemProperty to get the registry values and data.

In PowerShell, use a single asterisk (*) to get contents, instead of the traditional *.*
The format is interpreted literally, so *.* would not retrieve directories or file names without a dot.

#If you want it, here it is, come and get it, but you better hurry 'cos it's going fast# ~ Paul McCartney
