Folks, I was going through the tips section at extravirt.com ( http://www.xtravirt.com/index.php?option=com_content&task=view&id=53&Itemid=67) . Here they mention, how we can check the uptime of a machine.
When, I try to attempt the same command, echo $<uptime> I get a error message -bash: syntax error near unexpected token `newline'
Any ideas?
