# Based on https://superuser.com/a/1598420
# Compared to original SO answer, changed [string]$command parameter to a [scriptblock]

function Watch-Command {

Set-Alias -Name watch -Value Watch-Command

Added a powershell equivalent to watch. Note, you have the command in script block curlies { }.

Watch-Command {<command>}

watch { <command> }
