Get-Host
Gets an object that represents the current host program.
Syntax
Get-Host [] 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.
Examples
Example 1: Get information about the PowerShell console host
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.LocalRunspaceThis command displays information about the PowerShell console, which is the current host program for PowerShell in this example. It includes the name of the host, the version of 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 other useful properties. Later examples examine these properties.
Example 2: Resize the PowerShell window
$H = Get-Host
$Win = $H.UI.RawUI.WindowSize
$Win.Height = 10
$Win.Width = 10
$H.UI.RawUI.Set_WindowSize($Win)This command resizes the Windows PowerShell window to 10 lines by 10 characters.
Example 3: Get the PowerShell version for the host
(Get-Host).Version
Major Minor Build Revision
----- ----- ----- --------
5 1 22621 963This 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: Get the current culture for the host
(Get-Host).CurrentCulture | Format-List
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 - en-US
TextInfo : TextInfo - en-US
IsNeutralCulture : False
CultureTypes : SpecificCultures, InstalledWin32Cultures
NumberFormat : System.Globalization.NumberFormatInfo
DateTimeFormat : System.Globalization.DateTimeFormatInfo
Calendar : System.Globalization.GregorianCalendar
OptionalCalendars : {System.Globalization.GregorianCalendar}
UseUserOverride : True
IsReadOnly : TrueThis 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: Get the DateTimeFormat for the current culture
(Get-Host).CurrentCulture.DateTimeFormat | Format-List
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: Get the RawUI property for the host
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.
(Get-Host).UI.RawUI
ForegroundColor : Gray
BackgroundColor : Black
CursorPosition : 0,28
WindowPosition : 0,0
CursorSize : 25
BufferSize : 120,29
WindowSize : 120,29
MaxWindowSize : 120,29
MaxPhysicalWindowSize : 1904,69
KeyAvailable : True
WindowTitle : PowerShell 7.3.3Example 7: Set the background color for the PowerShell console
These commands change the background color of the Windows PowerShell console to black. The
Clear-Host command clears the screen to reset the console window to the new color.
(Get-Host).UI.RawUI.BackgroundColor = "Black"
Clear-HostThis change is effective only in the current session. To change the background color of the console for all sessions, add the command to your PowerShell profile.
Example 8: Set the background color for error messages
$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 *.
Inputs
None
You can't pipe objects to this cmdlet.
Outputs
System.Management.Automation.Internal.Host.InternalHost
This cmdlet returns an 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.
