grep idnum logfile|tail -1

like this...
logfile has
12345 status1.true
12345 status2.true
12345 status3.false
12345 status4.true
23452 status5.true
23452 status6.true
23452 status7.false
65243 status9.true

$ grep 23452 logfile |tail -1

will give you the last occurance of 23452 only - you could further do your testing of true or false by pulling the true or false with awk

$ grep 23452 logfile |tail -1|awk -F. '{print $2}'

Jifty::Web::Session::None(3pm)				User Contributed Perl Documentation			    Jifty::Web::Session::None(3pm)

NAME
Jifty::Web::Session::None - A null session handler for jifty DESCRIPTION
Jifty depends on its sessions to keep users logged in, to store continuations and to allow developers to store user-specific data. In general, you don't want to disable them. But sometimes, the development benefits of Jifty lead you to build applications that genuinely don't want per-user sessions. That's where "Jifty::Web::Session::None" comes in. By specifying that you want to use "Jifty::Web::Session::None" as your Jifty session handler, you tell Jifty to avoid ever reading, writing or storing a user session. No cookies get set. Nothing gets stored in the database. USAGE
In your "etc/config.yml": --- framework: Web: SessionClass:: Jifty::Web::Session::None METHODS
All methods in this class are dummy methods which do no work. This class mocks the API provided by "Jifty::Web::Session". new Takes no arguments. Returns a Jifty::Web::Session::None. id Returns false. create Returns true. load Returns true. unload Returns true. loaded Returns true. get Returns false. set Returns false. remove Returns true. set_continuation Returns false. get_continuation Returns false. remove_continuation Returns false. continuations Returns false. set_cookie Returns false. cookie_name Returns false. expires Returns false. perl v5.14.2 2010-09-25 Jifty::Web::Session::None(3pm)
