<p><br />Doesn't check properly... I tried your code in the place I usually put it (the find function) and it didn't do anything when logging in as guest, but forcing an echo of firefox still works fine and prevents a window manager.</p>
<p>I've tried $user $USER and $USERNAME... any other variables I might be able to try?</p>

<p>Hi Shima,</p>
<p>Using this method allows someone to start a window manager like Gnome and then do other things. If the user logging in is 'guest' I need them to be able to run absolutely nothing no matter what they have chosen except for the given command.</p>
<p>I'll try putting your code elsewhere to see if it can work better to get around this.</p>
<p>Thanks!</p>
