This is the built-in help made by Microsoft for the command 'Get-Host', in PowerShell version 5 - as retrieved from Windows version 'Microsoft Windows Server 2012 R2 Standard' PowerShell help files on 2016-06-23.

For PowerShell version 3 and up, where you have Update-Help, this command was run just before creating the web pages from the help files.


Gets an object that represents the current host program.


Get-Host [-InformationAction {SilentlyContinue | Stop | Continue | Inquire | Ignore | Suspend}] [-InformationVariable [<System.String>]] [<CommonParameters>]

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.

-------------------------- EXAMPLE 1 --------------------------

PS C:\>get-host

Name : ConsoleHost
Version : 2.0
InstanceId : e4e0ab54-cc5e-4261-9117-4081f20ce7a2
UI : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture : en-US
CurrentUICulture : en-US
PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
IsRunspacePushed : False
Runspace : System.Management.Automation.Runspaces.LocalRunspace

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

-------------------------- EXAMPLE 2 --------------------------

PS C:\>$h = get-host
PS C:\>$win = $h.ui.rawui.windowsize
PS C:\>$win.height = 10
PS C:\>$win.width = 10
PS C:\>$h.ui.rawui.set_windowsize($win)

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

-------------------------- EXAMPLE 3 --------------------------

PS C:\>(get-host).version | format-list -property *
Major : 2
Minor : 0
Build : -1
Revision : -1
MajorRevision : -1
MinorRevision : -1

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 --------------------------

PS C:\>(get-host).currentculture | format-list -property *

Parent : en
LCID : 1033
KeyboardLayoutId : 1033
Name : en-US
IetfLanguageTag : en-US
DisplayName : English (United States)
NativeName : English (United States)
EnglishName : English (United States)
TwoLetterISOLanguageName : en
ThreeLetterISOLanguageName : eng
ThreeLetterWindowsLanguageName : ENU
CompareInfo : CompareInfo - 1033
TextInfo : TextInfo - 1033
IsNeutralCulture : False
CultureTypes : SpecificCultures, InstalledWin32Cultures, FrameworkCultures
NumberFormat : System.Globalization.NumberFormatInfo
DateTimeFormat : System.Globalization.DateTimeFormatInfo
Calendar : System.Globalization.GregorianCalendar
OptionalCalendars : {System.Globalization.GregorianCalendar, System.Globalization.GregorianCalendar}
UseUserOverride : True
IsReadOnly : False

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.

-------------------------- EXAMPLE 5 --------------------------

PS C:\>(get-host).currentculture.DateTimeFormat | format-list -property *

AMDesignator : AM
Calendar : System.Globalization.GregorianCalendar
DateSeparator : /
FirstDayOfWeek : Sunday
CalendarWeekRule : FirstDay
FullDateTimePattern : dddd, MMMM dd, yyyy h:mm:ss tt
LongDatePattern : dddd, MMMM dd, yyyy
LongTimePattern : h:mm:ss tt
MonthDayPattern : MMMM dd
PMDesignator : PM
RFC1123Pattern : ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
ShortDatePattern : M/d/yyyy
ShortTimePattern : h:mm tt
SortableDateTimePattern : yyyy'-'MM'-'dd'T'HH':'mm':'ss
TimeSeparator : :
UniversalSortableDateTimePattern : yyyy'-'MM'-'dd HH':'mm':'ss'Z'
YearMonthPattern : MMMM, yyyy
AbbreviatedDayNames : {Sun, Mon, Tue, Wed...}
ShortestDayNames : {Su, Mo, Tu, We...}
DayNames : {Sunday, Monday, Tuesday, Wednesday...}
AbbreviatedMonthNames : {Jan, Feb, Mar, Apr...}
MonthNames : {January, February, March, April...}
IsReadOnly : False
NativeCalendarName : Gregorian Calendar
AbbreviatedMonthGenitiveNames : {Jan, Feb, Mar, Apr...}
MonthGenitiveNames : {January, February, March, April...}

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 --------------------------

PS C:\>(get-host).ui.rawui | format-list -property *

ForegroundColor : DarkYellow
BackgroundColor : DarkBlue
CursorPosition : 0,390
WindowPosition : 0,341
CursorSize : 25
BufferSize : 120,3000
WindowSize : 120,50
MaxWindowSize : 120,81
MaxPhysicalWindowSize : 182,81
KeyAvailable : False
WindowTitle : Windows PowerShell 2.0 (04/11/2008 00:08:14)

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 --------------------------

PS C:\>(get-host).ui.rawui.backgroundcolor = "Black"
PS C:\>cls

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 --------------------------

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

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 * ".
