shell script for logout on OSX?

[Terry Judd]

I have a situation where I want to logout the current user after an 
idle period. At the moment I'm invoking the Finder/System Events logout 
routine via Applescript but this throws up a standard answer style 
dialog that gives the user two minutes to cancel the logout before it 
proceeds. For various reasons (including the need to occasionally kill 
processes that fail to quit during an automated logout) I'd prefer to 
'bypass' this two minute warning if at all possible and initiate the 
logout immediately I have completed my 'cleanup' procedures (I already 
have a custom dialog that gives the user plenty of warning prior to 
issuing the logout call). Anyone have any ideas on if this is possible 
and how it might be done?

Cheers,

Terry...
