SYNOPSIS

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.

PARAMETERS

-AsSecureString

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