Read-Host

Module:: Microsoft.PowerShell.Utility

Reads a line of input from the console.

Syntax

Read-Host
    [[-Prompt] <Object>]
    [-AsSecureString]
    [<CommonParameters>]

Description

The Read-Host cmdlet reads a line of input from the console. You can use it to prompt a user for input. Because you can save the input as a secure string, you can use this cmdlet to prompt users for secure data, such as passwords, as well as shared data.

Examples

Example 1: Save console input to a variable

PS C:\> $Age = Read-Host "Please enter your age"

This command displays the string "Please enter your age:" as a prompt. When a value is entered and the Enter key is pressed, the value is stored in the $Age variable.

Example 2: Save console input as a secure string

PS C:\> $pwd_secure_string = Read-Host "Enter a Password" -AsSecureString

This command displays the string "Enter a Password:" as a prompt. As a value is being entered, asterisks ( ) appear on the console in place of the input. When the Enter key is pressed, the value is stored as a **SecureString * object in the $pwd_secure_string variable.

Optional Parameters

-AsSecureString

Indicates that the cmdlet displays asterisks (*) in place of the characters that the user types as input.

When you use this parameter, the output of the Read-Host cmdlet is a SecureString object ( System.Security.SecureString ).
