How do I get the current username in Windows PowerShell?

Retrieving the current username in Windows PowerShell can be achieved through several methods. Here are two common approaches:

1. Using the $env:USERNAME environment variable PowerShell includes several built-in environment variables, where $env:USERNAME directly stores the username of the currently logged-in user. Using this variable allows you to quickly retrieve the username. For example:

powershell
# Get the current username
$username = $env:USERNAME
Write-Host "Current user is: $username"

This script outputs the currently logged-in username.

1. Using the whoami command whoami is a commonly used command-line tool that displays detailed information about the currently active user. In PowerShell, you can directly use it to retrieve the current user's username. For example:

powershell
# Get and display the current username
$username = whoami
Write-Host "Current user is: $username"

This will directly display the current user's username.

Both methods are simple and effective. In practical applications, you can choose either method based on your needs.
