Get-Location

NAME
    Get-Location

SYNOPSIS
    Gets information about the current working location.

SYNTAX
    Get-Location [-PSDrive <string[]>] [-PSProvider <string[]>] [-UseTransaction] [<CommonParameters>]

    Get-Location [-Stack] [-StackName <string[]>] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Get-Location cmdlet gets an object that represents the current directory, much like the pwd (print working directory) command.

    When you move between Windows PowerShell drives, Windows PowerShell retains your location in each drive. You can use Get-Location to find your location in each drive.

    You can also use Get-Location to get the current directory at run time and use it in Functions and scripts, such as in a Function that displays the current directory in the Windows PowerShell prompt.

    If you use the Push-Location cmdlet to add locations to a path stack, you can use the Stack parameter of Get-Location to display the current stack.

PARAMETERS
    -PSDrive <string[]>
        Gets the current location in the specified Windows PowerShell drive.

        For example, if you are in the Certificate: drive, you can use this parameter to find your current location in the C: drive.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -PSProvider <string[]>
        Gets the current location in the drive supported by the specified Windows PowerShell provider.

        If the specified provider supports more than one drive, Get-Location returns the location on the most recently accessed drive.

        For example, if you are in the C: drive, you can use this parameter to find your current location in the drives of the Windows PowerShell Registry provider.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Stack [<SwitchParameter>]
        Displays the locations in the default path stack.

        To add paths to the default stack, use the Push-Location cmdlet.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -StackName <string[]>
        Displays the locations in the specified path stacks.

        To create path stacks, use the Push-Location cmdlet.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    PathInfo objects or StackInfo objects
        If you use the Stack or StackName parameters, Get-Location returns a StackInfo object. Otherwise, it returns a PathInfo object.

NOTES

        Locations can be stored on a stack. The Push-Location cmdlet adds a location to the top of the stack. The Pop-Location cmdlet gets the location at the top of the stack.

        The ways that the PSProvider, PSDrive, Stack, and StackName parameters interact depends on the provider. Some combinations will result in errors, such as specifying both a drive and a provider that does not expose that drive. If no parameters are specified, Get-Location returns the PathInfo object for the provider that contains the current working location.

        The Get-Location cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-Location

    Path
    —-
    C:\WINDOWS

    Description
    ———–
    This command displays your location in the current Windows PowerShell drive.

    For example, if you are in the Windows directory of the C: drive, it displays the path to that directory.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Set-Location

    Description
    ———–
    These commands demonstrate the use of Get-Location to display your current location in different Windows PowerShell drives.

    The first command uses the Set-Location cmdlet to set the current location to the Windows subdirectory of the C: drive.

        C:\PS> Set-Location C:\Windows

    The second command uses the Set-Location cmdlet to change the location to the HKLM:\Software\Microsoft Registry key. When you change to a location in the HKLM: drive, Windows PowerShell retains your location in the C: drive.

        PS C:\WINDOWS> Set-Location HKLM:\Software\Microsoft
        PS HKLM:\Software\Microsoft>

    The third command uses the Set-Location cmdlet to change the location to the “HKCU:\Control Panel\Input Method” Registry key.

        PS HKLM:\Software\Microsoft> Set-Location ‘HKCU:\Control Panel\Input Method’
        PS HKCU:\Control Panel\Input Method>

    The fourth command uses the Get-Location cmdlet to find the current location on the C: drive. It uses the PSDrive parameter to specify the drive.

        PS HKCU:\Control Panel\Input Method> Get-Location -PSDrive c
        Path
        —-
        C:\WINDOWS

    The fifth command uses the Set-Location cmdlet to return to the C: drive. Even though the command does not specify a subdirectory, Windows PowerShell returns you to the saved location.

        PS HKCU:\Control Panel\Input Method> Set-Location C:
        PS C:\WINDOWS>

    The sixth command uses the Get-Location cmdlet to find the current location in the drives supported by the Windows PowerShell Registry provider. Get-Location returns the location of the most recently accessed Registry drive, HKCU:.

        PS C:\WINDOWS> Get-Location -PSProvider Registry
        Path
        —-
        HKCU:\Control Panel\Input Method

    To see the current location in the HKLM: drive, you need to use the PSDrive parameter to specify the drive. The seventh command does just this:

        PS C:\WINDOWS> Get-Location -PSDrive HKLM
        Path
        —-
        HKLM:\Software\Microsoft

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-Location

    Description
    ———–
    These commands show how to use the Stack and StackName parameters of Get-Location to list the paths in the default and alternate path stacks.

    The first command sets the current location to the Windows directory on the C: drive.

        C:\PS> Set-Location C:\Windows

    The second command uses the Push-Location cmdlet to push the current location (C:\Windows) onto the path stack and change to the System32 subdirectory. Because no stack is specified, the current location is pushed onto the default stack.
        C:\WINDOWS>Push-Location System32

    The third command pushes the current location (C:\Windows\System32) onto the Stack2 stack and changes the location to the WindowsPowerShell subirectory.

        C:\Windows\System32>Push-Location WindowsPowerShell -stack Stack2

    The fourth command uses the Get-Location cmdlet to get the paths on the default path stack.

        C:\WINDOWS\system32\WindowsPowerShell>Get-Location -stack

        Path
        —-
        C:\WINDOWS

    The last command uses the StackName parameter of Get-Location to get the paths on the Stack2 stack.

        C:\WINDOWS\system32\WindowsPowerShell>Get-Location -stackname Stack2

        Path
        —-
        C:\WINDOWS\system32

    ————————– EXAMPLE 4 ————————–

    C:\PS>function prompt { ‘PowerShell: ‘ + (Get-Location) + ‘> ‘}

    PowerShell: C:\WINDOWS>

    Description
    ———–
    This example shows how to customize the Windows PowerShell prompt. The Function that defines the prompt includes a Get-Location command, which is run whenever the prompt appears in the console.

    The format of the default Windows PowerShell prompt is defined by a special Function called “prompt”. You can change the prompt in your console by creating a new Function called “prompt”.

    To see the current prompt Function, type the following command:

        Get-Content Function:prompt

    The command begins with the “function” keyword followed by the Function name, “prompt”. The Function body appears within braces ( {} ).

    This command defines a new prompt that begins with the string “PowerShell: “. To append the current location, it uses a Get-Location command, which runs when the prompt Function is called. The prompt ends with the string “> “.

cmdlet, Get, Member

Get-Member

NAME
    Get-Member

SYNOPSIS
    Gets the properties and methods of objects.

SYNTAX
    Get-Member [[-Name] <string[]>] [-Force] [-InputObject <psobject>] [-MemberType {AliasProperty | CodeProperty | Property | NoteProperty | ScriptProperty | Properties | PropertySet | Method | CodeMethod | ScriptMethod | Methods | ParameterizedProperty | MemberSet | Event | All}] [-Static] [-View {Extended | Adapted | Base | All}] [<CommonParameters>]

DESCRIPTION
    The Get-Member cmdlet gets the “members” (properties and methods) of objects.

    To specify the object, use the InputObject parameter or pipe an object to Get-Member. To retrieve information about static members (members of the class, not of the instance), use the Static parameter. To get only certain types of members, such as NoteProperties, use the MemberType parameter.

PARAMETERS
    -Force [<SwitchParameter>]
        Adds the intrinsic members (PSBase, PSAdapted, PSObject, PSTypeNames) and the compiler-generated get_ and set_ methods to the display. By default, Get-Member gets these properties in all views other than “Base” and “Adapted,” but it does not display them.

        The following list describes the properties that are added when you use the Force parameter:

        — PSBase: The original properties of the .NET Framework object without extension or adaptation. These are the properties defined for the object class and listed in MSDN.
        — PSAdapted: The properties and methods defined in the Windows PowerShell extended type system.
        — PSExtended: The properties and methods that were added in the Types.ps1xml files or by using the Add-Member cmdlet.
        — PSObject: The adapter that converts the base object to a Windows PowerShell PSObject object.
        — PSTypeNames: A list of object types that describe the object, in order of specificity. When formatting the object, Windows PowerShell searches for the types in the Format.ps1xml files in the Windows PowerShell installation directory ($pshome). It uses the formatting definition for the first type that it finds.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -InputObject <psobject>
        Specifies the object whose members are retrieved.

        Using the InputObject parameter is not the same as piping an object to Get-Member. The differences are as follows:

        — When you pipe a collection of objects to Get-Member, Get-Member gets the members of the individual objects in the collection, such as the properties of the integers in an array of integers.

        — When you use InputObject to submit a collection of objects, Get-Member gets the members of the collection, such as the properties of the array in an array of integers.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByValue)
        Accept wildcard characters? false

    -MemberType <PSMemberTypes>
        Gets only members with the specified member type. The default is All.

        The valid values for this parameter are:

        — AliasProperty: A property that defines a new name for an existing property.
        — CodeMethod: A method that references a static method of a .NET Framework class.
        — CodeProperty: A property that references a static property of a .NET Framework class.
        — Event: Indicates that the object sends a message to indicate an action or a change in state.
        — MemberSet: A predefined collection of properties and methods, such as PSBase, PSObject, and PSTypeNames.
        — Method: A method of the underlying .NET Framework object.
        — NoteProperty: A property with a static value.
        — ParameterizedProperty: A property that takes parameters and parameter values.
        — Property: A property of the underlying .NET Framework object.
        — PropertySet: A predefined collection of object properties.
        — ScriptMethod: A method whose value is the output of a script.
        — ScriptProperty: A property whose value is the output of a script.

        — All: Gets all member types.
        — Methods: Gets all types of methods of the object (for example, Method, CodeMethod, ScriptMethod).
        — Properties: Gets all types of properties of the object (for example, Property, CodeProperty, AliasProperty, ScriptProperty).

        Not all objects have every type of member. If you specify a member type that the object does not have, Windows PowerShell returns a null value.

        To get related types of members, such as all extended members, use the View parameter. If you use the MemberType parameter with the Static or View parameters, Get-Member gets the members that belong to both sets.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Name <string[]>
        Specifies the names of one or more properties or methods of the object. Get-Member gets only the specified properties and methods.

        If you use the Name parameter with the MemberType, View, or Static parameters, Get-Member gets only the members that satisfy the criteria of all parameters.

        To get a static member by name, use the Static parameter with the Name parameter.

        Required?                    false
        Position?                    1
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Static [<SwitchParameter>]
        Gets only the static properties and methods of the object.

        Static properties and methods are defined on the class of objects, not on any particular instance of the class.

        If you use the Static parameter with the View parameter, the View parameter is ignored. If you use the Static parameter with the MemberType parameter, Get-Member gets only the members that belong to both sets.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -View <PSMemberViewTypes>
        Gets only particular types of members (properties and methods). Specify one or more of the values. The default is “Adapted, Extended”.

        Valid values are:
        — Base: Gets only the original properties and methods of the .NET Framework object (without extension or adaptation).
        — Adapted: Gets only the properties and methods defined in the Windows PowerShell extended type system.
        — Extended: Gets only the properties and methods that were added in the Types.ps1xml files or by using the Add-Member cmdlet.
        — All: Gets the members in the Base, Adapted, and Extended views.

        The View parameter determines the members retrieved, not just the display of those members.

        To get particular member types, such as script properties, use the MemberType parameter. If you use the MemberType and View parameters in the same command, Get-Member gets the members that belong to both sets. If you use the Static and View parameters in the same command, the View parameter is ignored.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.Management.Automation.PSObject
        You can pipe any object to Get-Member

OUTPUTS
    Microsoft.PowerShell.Commands.MemberDefinition
        Get-Member returns an object for each property or method that its gets.

NOTES

        You can retrieve information about a collection object either by using the InputObject parameter or by piping the object, preceded by a comma, to Get-Member.

    Description
    ———–
    This command displays the properties and methods of the process objects (System.ServiceProcess.ServiceController) that are generated by the Get-Service cmdlet.

    The command uses the pipeline operator (|) to send the output of a Get-Service command to Get-Member.

    Because the Get-Member part of the command does not have any parameters, it uses all of the default values. As such, it gets all member types, but it does not get static members and does not display intrinsic members.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Service | Get-Member -Force

    C:\PS> (Get-Service -schedule).psbase

    Description
    ———–
    This example gets all of the members (properties and methods) of the service objects (System.ServiceProcess.ServiceController) retrieved by the Get-Service cmdlet, including the intrinsic members, such as PSBase and PSObject, and the get_ and set_ methods.

    The first command uses the Get-Service cmdlet to get objects that represent the services on the system. It uses a pipeline operator (|) to pass the service objects to the Get-Member cmdlet.

    The Get-Member command uses the Force parameter to add the intrinsic members and compiler-generated members of the objects to the display. Get-Member gets these members, but it hides them by default.

    You can use these properties and methods in the same way that you would use an adapted method of the object. The second command shows how to display the value of the PSBase property of the Schedule service.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-Service    | Get-Member -View extended

     TypeName: System.ServiceProcess.ServiceController

    Name MemberType    Definition
    —- ———-    ———-
    Name AliasProperty Name = ServiceName

    Description
    ———–
    This command gets the methods and properties of service objects that were extended by using the Types.ps1xml file or the Add-Member cmdlet.

    The Get-Member command uses the View parameter to get only the extended members of the service objects. In this case, the extended member is the Name property, which is an Alias property of the ServiceName property.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-Eventlog -log system | gm -MemberType scriptproperty

     TypeName: System.Diagnostics.EventLogEntry

    Name    MemberType     Definition
    —-    ———-     ———-
    EventID ScriptProperty System.Object EventID {get=$this.get_EventID() -band 0xFFFF;}

    Description
    ———–
    This command gets the script properties of event log objects in the System log in Event Viewer. In this case, the only script property is the EventID.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-Eventlog -log system | Get-Member -MemberType scriptproperty

    EventID ScriptProperty System.Object EventID {get=$this.get_EventID() -band 0xFFFF;}

    Description
    ———–
    This command gets the script properties of event log objects in the System log in Event Viewer.

    The command uses the MemberType parameter to get only objects with a value of AliasProperty for their MemberType property.

    The command returns the EventID property of the EventLog object.

    ————————– EXAMPLE 6 ————————–

    C:\PS>$a = “Get-Process“, “Get-Service“, “Get-Culture“, “Get-PSDrive“, “Get-ExecutionPolicy”

    C:\PS> foreach ($cmdlet in $a) {Invoke-Expression $cmdlet | Get-Member -Name machinename}

     TypeName: System.ServiceProcess.ServiceController

    Name        MemberType Definition
    —-        ———- ———-
    MachineName Property System.String MachineName {get;set;}

    Description
    ———–
    This command gets objects that have a MachineName property from a list of cmdlets.

    The first command stores the names of several cmdlets in the $a Variable.

    The second command uses a ForEach statement to invoke each command, send the results to Get-Member, and limit the results from Get-Member to members that have the name “MachineName.”

    The results show that only process objects (System.Diagnostics.Process) and service objects (System.ServiceProcess.ServiceController) have a MachineName property.

    ————————– EXAMPLE 7 ————————–

    C:\PS>$a = Get-Member -InputObject @(1)

    Description
    ———–
    This example demonstrates how to find the properties and methods of an array of objects when you have only one object of the given type.

    Because the goal of the command is to find the properties of an array, the first command uses the InputObject parameter. It uses the “at” symbol (@) to indicate an array. In this case, the array contains only one object, the integer 1.

    The third command uses the Get-Member cmdlet to get the properties and methods of an array of integers, and the command saves them in the $a Variable.

    The fourth command uses the Count property of the array to find the number of objects in the $a Variable.

cmdlet, Get, Item

Get-Item

NAME
    Get-Item

SYNOPSIS
    Gets the item at the specified location.

SYNTAX
    Get-Item [-LiteralPath] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-UseTransaction] [<CommonParameters>]

    Get-Item [-Path] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Get-Item cmdlet gets the item at the specified location. It does not get the contents of the item at the location unless you use a wildcard character (*) to request all the contents of the item.

    The Get-Item cmdlet is used by Windows PowerShell providers to enable you to navigate through different types of data stores.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user-name, such as “User01” or “Domain01\User01”, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

        This parameter is not supported by any providers installed with Windows PowerShell.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Exclude <string[]>
        Omits the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        The Exclude parameter is effective only when the command includes the contents of an item, such as C:\Windows\*, where the wildcard character specifies the contents of the C:\Windows directory.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Filter <string>
        Specifies a filter in the provider’s format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects, rather than having Windows PowerShell filter the objects after they are retrieved.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Allows the cmdlet to get items that cannot otherwise be accessed, such as hidden items. Implementation varies from provider to provider. For more information, see about_providers. Even using the Force parameter, the cmdlet cannot override security restrictions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Include <string[]>
        Retrieves only the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        The Include parameter is effective only when the command includes the contents of an item, such as C:\Windows\*, where the wildcard character specifies the contents of the C:\Windows directory.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -LiteralPath <string[]>
        Specifies a path to the item. Unlike Path, the value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Path <string[]>
        Specifies the path to an item. Get-Item gets the item at the specified location. Wildcards are permitted. This parameter is required, but the parameter name (“Path”) is optional.

        Use a dot (.) to specify the current location. Use the wildcard character (*) to specify all the items in the current location.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.String
        You can pipe a string that contains a path to Get-Item.

OUTPUTS
    Object
        Get-Item returns the objects that it gets. The type is determined by the type of objects in the path.

NOTES

        You can also refer to Get-Item by its built-in Alias, “gi”. For more information, see about_aliases.

        Get-Item does not have a Recurse parameter, because it gets only an item, not its contents. To get the contents of an item recursively, use Get-ChildItem.

        To navigate through the Registry, use Get-Item to get Registry keys and Get-ItemProperty to get Registry values and data. The Registry values are considered to be properties of the Registry key.

        The Get-Item cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-Item C:\

    Description
    ———–
    This command gets the current directory of the C: drive. The object that is retrieved represents only the directory, not its contents.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-Item C:\*

    Description
    ———–
    This command gets the items in the C: drive. The wildcard character (*) represents all the items in the container, not just the container.

    In Windows 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.

    ————————– EXAMPLE 5 ————————–

    C:\PS>(Get-Item C:\Windows).LastAccessTime

    Description
    ———–
    This command gets the LastAccessTime property of the C:\Windows directory. LastAccessTime is just one property of file system directories. To see all of the properties of a directory, type “(Get-Item <directory-name>) | Get-Member“.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Get-Item hklm:\software\microsoft\powershell\1\shellids\microsoft.powershell\*

    Description
    ———–
    This command shows the contents of the Microsoft.PowerShell Registry key. You can use Get-Item with the Windows PowerShell Registry provider to get Registry keys and subkeys, but you must use Get-ItemProperty to get the Registry values and data.

    ————————– EXAMPLE 7 ————————–

    C:\PS>Get-Item c:\Windows\* -Include *.* -Exclude w*

    Description
    ———–
    This command gets items in the Windows directory with names that include a dot (.), but do not begin with w*. This command works only when the path includes a wildcard character (*) to specify the contents of the item.

cmdlet, Get, ItemProperty

Get-ItemProperty

NAME
    Get-ItemProperty

SYNOPSIS
    Gets the properties of a specified item.

SYNTAX
    Get-ItemProperty [-LiteralPath] <string[]> [[-Name] <string[]>] [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Include <string[]>] [-UseTransaction] [<CommonParameters>]

    Get-ItemProperty [-Path] <string[]> [[-Name] <string[]>] [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Include <string[]>] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Get-ItemProperty cmdlet gets the properties of the specified items. For example, you can use Get-ItemProperty to get the value of the LastAccessTime property of a file object. You can also use Get-ItemProperty to view Registry entries and their values.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user name, such as “User01” or “Domain01\User01”, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

        This parameter is not supported by any providers installed with Windows PowerShell.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Exclude <string[]>
        Omits the specified items. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Filter <string>
        Specifies a filter in the provider’s format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects rather than having Windows PowerShell filter the objects after they are retrieved.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Include <string[]>
        Includes the specified items.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -LiteralPath <string[]>
        Specifies a path to the item property. The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Name <string[]>
        Specifies the name of the property or properties to retrieve.

        Required?                    false
        Position?                    2
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Path <string[]>
        Specifies the path to the item or items.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.String
        You can pipe a string that contains a path to Get-ItemProperty.

OUTPUTS
    Object
        Get-ItemProperty returns an object for each item property that it gets. The object type depends on the object that is retrieved.

NOTES

        The Get-ItemProperty cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-Itemproperty C:\Windows

    Description
    ———–
    This command gets information about the C:\Windows directory.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Itemproperty C:\Test\Weather.xls | Format-List

    Description
    ———–
    This command gets the properties of the C:\Test\Weather.xls file. The result is piped to the Format-List cmdlet to display the output as a list.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-Itemproperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion

    Description
    ———–
    This command displays the value name and data of each of the Registry entries contained in the CurrentVersion Registry subkey. Note that the command requires that there is a Windows PowerShell drive named HKLM: that is mapped to the HKEY_LOCAL_MACHINE hive of the Registry. A drive with that name and mapping is available in Windows PowerShell by default. Alternatively, the path to this Registry subkey can be specified by using the following alternative path that begins with the provider name followed by two colons:
    Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-Itemproperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion `
    -Name “ProgramFilesDir”

    Description
    ———–
    This command gets the value name and data of the ProgramFilesDir Registry entry in the CurrentVersion Registry subkey. The command uses the Path parameter to specify the subkey and the Name parameter to specify the value name of the entry.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-Itemproperty -Path HKLM:\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine

    ApplicationBase         : C:\Windows\system32\WindowsPowerShell\v1.0\

    PSCompatibleVersion     : 1.0,2.0

    Description
    ———–
    This command gets the value names and data of the Registry entries in the PowerShellEngine Registry key. The results are shown in the following sample output.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Get-Itemproperty -Path HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell

    PSProvider     : Microsoft.PowerShell.Core\Registry
    Path            : C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe
    ExecutionPolicy : RemoteSigned

    Description
    ———–
    This example shows how to format the output of a Get-ItemProperty command in a list to make it easy to see the Registry values and data and to make it easy to interpret the results.

    The first command uses the Get-ItemProperty cmdlet to get the Registry entries in the Microsoft.PowerShell subkey. This subkey stores options for the default shell for Windows PowerShell. The results are shown in the following sample output.

    The output shows that there are two Registry entries, Path and ExecutionPolicy. When a Registry key contains fewer than five entries, by default it is displayed in a table, but it is often easier to view in a list.

    The second command uses the same Get-ItemProperty command. However, this time, the command uses a pipeline operator (|) to send the results of the command to the Format-List cmdlet. The Format-List command uses the Property parameter with a value of * (all) to display all of the properties of the objects in a list. The results are shown in the following sample output.

    The resulting display shows the Path and ExecutionPolicy Registry entries, along with several less familiar properties of the Registry key object. The other properties, prefixed with “PS”, are properties of Windows PowerShell custom objects, such as the objects that represent the Registry keys.

cmdlet, Get, History

Get-History

NAME
    Get-History

SYNOPSIS
    Gets a list of the commands entered during the current session.

SYNTAX
    Get-History [[-Id] <Int64[]>] [[-Count] <int>] [<CommonParameters>]

DESCRIPTION
    The Get-History cmdlet gets the session history, that is, the list of commands entered during the current session. Windows PowerShell automatically maintains a history of each session. You can save the session history in XML or CSV format. By default, history files are saved in the home directory, but you can save the file in any location.

PARAMETERS
    -Count <int>
        Displays the specified number of the most recent history entries. The default is 32. If you use both the Count and Id parameters in a command, the display ends with the command specified by the Id parameter.

        Required?                    false
        Position?                    2
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Id <Int64[]>
        Specifies the ID number of a command in the session history. Get-History gets only the specified command. If you use Id and Count, Get-History gets the most recent commands ending with the command specified by the Id parameter.

        Required?                    false
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue)
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    Int64
        You can pipe a history ID to Get-History.

OUTPUTS
    Microsoft.PowerShell.Commands.HistoryInfo
        Get-History returns a history object for each history item that it gets.

NOTES

        The session history is a list of the commands entered during the session along with the ID. The session history represents the order of execution, the status, and the start and end times of the command. As you enter each command, Windows PowerShell adds it to the history so that you can reuse it. For more information about the command history, see about_History.

        You can also refer to Get-History by its built-in Aliases, “h”, “history”, and “ghy”. For more information, see about_aliases.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-History

    Description
    ———–
    This command gets the 32 most recently submitted commands. The default display shows each command and its ID, which indicates the order of execution.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-History | Where-Object {$_.commandLine -like “*service*”}

    Description
    ———–
    This command gets entries from the command history that include the word, “service”. The first command gets the 32 most recent entries in the session history. The pipeline operator (|) passes the results to the Where-Object cmdlet, which selects only the commands that include “service”.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-History -Id 7 -Count 5 | Export-Csv history.csv

    Description
    ———–
    This command gets the five most recent history entries ending with entry 7. The pipeline operator (|) passes the result to the Export-Csv cmdlet, which formats the history as comma-separated text and saves it in the History.csv file. The file includes the data that is displayed when you format the history as a list, including the status and start and end times of the command.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-History -Count 1

    Description
    ———–
    This command gets the last (most recently entered) command in the command history. It uses the Count parameter to display just one command. By default, Get-History displays the most recent commands. This command can be abbreviated to “h -c 1” and is equivalent to pressing the up-arrow key.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-History -Count $MaximumHistoryCount

    Description
    ———–
    This command displays all of the commands saved in the session history. By default, $MaximumHistoryCount is 64, so this command can be abbreviated as “h -c 64”.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Get-History | Format-List

    Description
    ———–
    This command displays all of the properties of entries in the session history. The pipeline operator (|) passes the result to the Format-List cmdlet, which displays all of the properties of each history entry, including the ID, status, and start and end times of the command.

cmdlet, Get, Host

Get-Host

NAME
    Get-Host

SYNOPSIS
    Gets an object that represents the current host program. And, displays Windows PowerShell version and regional information by default.

SYNTAX
    Get-Host [<CommonParameters>]

DESCRIPTION
    The Get-Host cmdlet gets an object that represents the program that is hosting Windows PowerShell.

    The default display includes the Windows PowerShell version number and the current region and language settings that the host is using, but the host object contains a wealth of information, including detailed information about the version of Windows PowerShell that is currently running and the current culture and UI culture of Windows PowerShell. You can also use this cmdlet to customize features of the host program user interface, such as the text and background colors.

PARAMETERS
    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    System.Management.Automation.Internal.Host.InternalHost
        Get-Host returns a System.Management.Automation.Internal.Host.InternalHost object.

NOTES

        The $host automatic Variable contains the same object that Get-Host returns, and you can use it in the same way. Similarly, the $PSCulture and $PSUICulture automatic Variables contain the same objects that the CurrentCulture and CurrentUICulture properties of the host object contain. You can use these features interchangeably.

        For more information, see about_Automatic_Variables.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-Host

    Name             : ConsoleHost
    Version         : 2.0
    InstanceId     : e4e0ab54-cc5e-4261-9117-4081f20ce7a2

    CurrentUICulture : en-US
    PrivateData     : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
    IsRunspacePushed : False
    Runspace         : System.Management.Automation.Runspaces.LocalRunspace

    Description
    ———–
    This command displays information about the Windows PowerShell console, which is the current host program for Windows PowerShell in this example. It includes the name of the host, the version of Windows PowerShell that is running in the host, and current culture and UI culture.

    The Version, UI, CurrentCulture, CurrentUICulture, PrivateData, and Runspace properties each contain an object with very useful properties. Later examples examine these properties.

    ————————– EXAMPLE 2 ————————–

    C:\PS>$h = Get-Host

    C:\PS> $win = $h.ui.rawui.windowsize

    C:\PS> $win.height = 10

    C:\PS> $win.width = 10

    C:\PS> $h.ui.rawui.set_windowsize($win)

    Description
    ———–
    This command resizes the Windows PowerShell window to 10 pixels by 10 pixels.

    ————————– EXAMPLE 3 ————————–

    Revision     : -1
    MajorRevision : -1
    MinorRevision : -1

    Description
    ———–
    This command gets detailed information about the version of Windows PowerShell running in the host. You can view, but not change, these values.

    The Version property of Get-Host contains a System.Version object. This command uses a pipeline operator (|) to send the version object to the Format-List cmdlet. The Format-List command uses the Property parameter with a value of all (*) to display all of the properties and property values of the version object.

    ————————– EXAMPLE 4 ————————–

    UseUserOverride                : True
    IsReadOnly                     : False

    Description
    ———–
    This command gets detailed information about the current culture set for Windows PowerShell running in the host. This is the same information that is returned by the Get-Culture cmdlet.

    (Similarly, the CurrentUICulture property returns the same object that Get-UICulture returns.)

    The CurrentCulture property of the host object contains a System.Globalization.CultureInfo object. This command uses a pipeline operator (|) to send the CultureInfo object to the Format-List cmdlet. The Format-List command uses the Property parameter with a value of all (*) to display all of the properties and property values of the CultureInfo object.

    AbbreviatedMonthGenitiveNames    : {Jan, Feb, Mar, Apr…}
    MonthGenitiveNames             : {January, February, March, April…}

    Description
    ———–
    This command returns detailed information about the DateTimeFormat of the current culture that is being used for Windows PowerShell.

    The CurrentCulture property of the host object contains a CultureInfo object that, in turn, has many useful properties. Among them, the DateTimeFormat property contains a DateTimeFormatInfo object with many useful properties.

    To find the type of an object that is stored in an object property, use the Get-Member cmdlet. To display the property values of the object, use the Format-List cmdlet.

    ————————– EXAMPLE 6 ————————–

    C:\PS>(Get-Host).ui.rawui | Format-List -property *

    MaxPhysicalWindowSize : 182,81
    KeyAvailable         : False
    WindowTitle         : Windows PowerShell 2.0 (04/11/2008 00:08:14)

    Description
    ———–
    This command displays the properties of the RawUI property of the host object. By changing these values, you can change the appearance of the host program.

    ————————– EXAMPLE 7 ————————–

    C:\PS>(Get-Host).ui.rawui.backgroundcolor = “Black”

    C:\PS> cls

    Description
    ———–
    These commands change the background color of the Windows PowerShell console to black. The “cls” command is an Alias for the Clear-Host Function, which clears the screen and changes the whole screen to the new color.

    This change is effective only in the current session. To change the background color of the console for all sessions, add the command to your Windows PowerShell profile.

    ————————– EXAMPLE 8 ————————–

    C:\PS>$host.privatedata.errorbackgroundcolor = “white”

    Description
    ———–
    This command changes the background color of error messages to white.

    This command uses the $host automatic Variable, which contains the host object for the current host program. Get-Host returns the same object that $host contains, so you can use them interchangeably.

    This command uses the PrivateData property of $host as its ErrorBackgroundColor property. To see all of the properties of the object in the $host.privatedata property, type “$host.privatedata | Format-List * “.

    Get-Help [-Parameter <string>] [[-Name] <string>] [-Category <string[]>] [-Component <string[]>] [-Functionality <string[]>] [-Online] [-Path <string>] [-Role <string[]>] [<CommonParameters>]

DESCRIPTION
    The Get-Help cmdlet displays information about Windows PowerShell concepts and commands, including cmdlets, providers, Functions and scripts. To get a list of all cmdlet help topic titles, type “Get-Help *”.

    If you type “Get-Help” followed by the exact name of a help topic, or by a word unique to a help topic, Get-Help displays the topic contents. If you enter a word or word pattern that appears in several help topic titles, Get-Help displays a list of the matching titles. If you enter a word that does not appear in any help topic titles, Get-Help displays a list of topics that include that word in their contents.

    In addition to “Get-Help“, you can also type “help” or “man”, which displays one screen of text at a time, or “<cmdlet-Name> -?”, which is identical to Get-Help but works only for cmdlets.

    You can display the entire help file or selected parts of the file, such as the syntax, parameters, or examples. You can also use the Online parameter to display an online version of a help file in your Internet browser. These parameters have no effect on conceptual help topics.

    Conceptual help topics in Windows PowerShell begin with “about_”, such as “about_Comparison_Operators”. To see all “about_” topics, type “Get-Help about_*”. To see a particular topic, type “Get-Help about_<topic-Name>”, such as “Get-Help about_Comparison_Operators“.

NOTES

        Without parameters, “Get-Help” displays information about the Windows PowerShell help system.

        The full view of help (-Full) includes a table of information about the parameters. The table includes the following fields:

        — Required: Indicates whether the parameter is required (true) or optional (false).

        — Position: Indicates whether the parameter is named or positional (numbered). Positional parameters must appear in a specified place in the command.

        — “Named” indicates that the parameter name is required, but that the parameter can appear anywhere in the command.

        — <Number> indicates that the parameter name is optional, but when the name is omitted, the parameter must be in the place specified by the number. For example, “2” indicates that when the parameter name is omitted, the parameter must be the second (2) or only unnamed parameter in the command. When the parameter name is used, the parameter can appear anywhere in the command.

        — Default value: The parameter value that Windows PowerShell uses if you do not include the parameter in the command.

        — Accepts pipeline input: Indicates whether you can (true) or cannot (false) send objects to the parameter through a pipeline. “By Property Name” means that the pipelined object must have a property with the same name as the parameter name.

        — Accepts wildcard characters: Indicates whether the value of a parameter can include wildcard characters, such as * and ?.

    …

    Description
    ———–
    This example shows how to get help for the Get-Item cmdlet that explains how to use the cmdlet in the DataCollection node of the Windows PowerShell SQL Server provider.

    The example shows two ways of getting the custom help for Get-Item.

    The first command uses the Path parameter of Get-Help to specify the provider path. This command can be entered at any path location.

    The second command uses the Set-Location cmdlet (alias = “cd”) to go to the provider path. From that location, even without the Path parameter, the Get-Help command gets the custom help for the provider path.

    The third command shows that a Get-Help command in a file system path, and without the Path parameter, gets the standard help for the Get-Item cmdlet.

    ————————– EXAMPLE 15 ————————–

    C:\PS>Get-Help c:\ps-test\MyScript.ps1

    Description
    ———–
    This command gets help for the MyScript.ps1 script. For information about writing help for your Functions and scripts, see about_Comment_Based_Help.

Get-ExecutionPolicy

NAME
    Get-ExecutionPolicy

SYNOPSIS
    Gets the execution policies for the current session.

SYNTAX
    Get-ExecutionPolicy [[-Scope] {Process | CurrentUser | LocalMachine | UserPolicy | MachinePolicy}] [-List] [<CommonParameters>]

DESCRIPTION
    The Get-ExecutionPolicy cmdlet gets the execution policies for the current session.

    The execution policy is determined by execution policies that you set by using Set-ExecutionPolicy and the Group Policy settings for the Windows PowerShell execution policy. The default value is “Restricted.”

    Without parameters, Get-ExecutionPolicy gets the execution policy that is effective in the session. You can use the List parameter to get all execution policies that affect the session or the Scope parameter to get the execution policy for a particular scope.

    For more information, see about_execution_policies.

PARAMETERS
    -List [<SwitchParameter>]
        Gets all execution policy values for the session listed in precedence order. By default, Get-ExecutionPolicy gets only the effective execution policy.

        Required?                    false
        Position?                    named
        Default value                False
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Scope <ExecutionPolicyScope>
        Gets the execution policy in the specified scope. By default, Get-ExecutionPolicy gets the effective execution policy for the current session.

        Valid values are:

        — MachinePolicy: The execution policy set by a Group Policy for all users of the computer.
        — UserPolicy: The execution policy set by a Group Policy for the current user of the computer.
        — Process: The execution policy that is set for the current Windows PowerShell process.
        — CurrentUser: The execution policy that is set for the current user.
        — LocalMachine: The execution policy that is set for all users of the computer.

        Required?                    false
        Position?                    1
        Default value                Effective execution policy
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    Microsoft.PowerShell.ExecutionPolicy
        Get-ExecutionPolicy returns an object for each execution policy that it gets.

NOTES

        You cannot use Get-ExecutionPolicy to get particular execution policies set for a particular scope or to get the execution policy set by a Group Policy. Get-ExecutionPolicy only gets the effective execution policy that results from applying all precedence rules.

        The execution policy is part of the security strategy of Windows PowerShell. It determines whether you can load configuration files (including your Windows PowerShell profile) and run scripts, and it determines which scripts, if any, must be digitally signed before they will run.

        The effective execution policy is determined by the policies that you set by using Set-ExecutionPolicy and the “Turn on Script Execution” group policies for computers and users. The precedence order is Computer Group Policy > User Group Policy > Process (session) execution policy > User execution policy > Computer execution policy.

        For more information about Windows PowerShell execution policy, including definitions of the Windows PowerShell policies, see about_execution_policies.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-ExecutionPolicy

    Restricted

    Description
    ———–
    This command gets the current execution policy for the shell.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Set-ExecutionPolicy RemoteSigned; Get-ExecutionPolicy

    RemoteSigned

    Description
    ———–
    These commands set a new user preference for the shell execution policy and then display the effective execution policy. The commands are separated by a semicolon (;). In this example, because there is no Group Policy setting, the user preference is the effective policy for the shell.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-ExecutionPolicy -List

            Scope ExecutionPolicy
            —– —————
    MachinePolicy Undefined
     UserPolicy Undefined

     CurrentUser AllSigned
     LocalMachine RemoteSigned

    C:\PS> Get-ExecutionPolicy
    AllSigned

    Description
    ———–
    These commands get all execution policies in the current session and the effective execution policy.

    The first command gets all execution policies that affect the current session. The policies are listed in precedence order.

    The second command gets only the effective execution policy, which is the one set in the CurrentUser scope.

    Description
    ———–
    This example shows how to use Get-FormatData and Export-FormatData to export the formatting data that is added by a module.

    The first four commands use the Get-FormatData, Import-Module, and Compare-Object cmdlets to identify the format type that the BitsTransfer module adds to the session.

    The fifth command uses the Get-FormatData cmdlet to get the format type that the BitsTransfer module adds. It uses a pipeline operator (|) to send the format type object to the Export-FormatData cmdlet, which converts it back to XML and saves it in the specified format.ps1xml file.

    The final command shows an excerpt of the format.ps1xml file content.
