Discovering Useful Console Commands

There are plenty of useful console commands such as ipconfig, whoami, and systeminfo. Most of these commands hide inside the Windows folder. Here's a clever function that lists all available commands with a short description of what they do in a window:

function Get-ConsoleCommand
{
$ext = $env:pathext -split '' -replace '\.','*.'
$desc = @{N='Description' E={$_.FileVersionInfo.FileDescription}}
Get-Command -Name $ext | 
   Select-Object Name, Extension, $desc |
   Out-GridView
}
PS> Get-ConsoleCommand
