Read-Host

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

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

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

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).
