Sorry, but that number difference is because:<br>- when root is logged in, you have used "su root", so there are two users: 1) root 2) (already open) me<br>- when "me" is logged in, there are only 1 user which is "me".
<br><br>I hope it's clear enough. <br>So is this all problem? or is it only a sample?<br><br>Summary: To see which users are logged in, you can use command "w" as a sample:<br><span style="background-color: rgb(192, 192, 192); font-family: courier new,monospace;">
