Anyone got a quick code snippet I can add to my crontab? Since Rails doesn''t do any housekeeping, my /tmp directory just keeps getting fatter and fatter. I found this useless snippet in the Agile book: find /tmp/ -name ''ruby_sess*'' -ctime +12h -delete Fedora Linux complains about the ''h'' in 12h, then if you remove the ''h'' he complains about the ''-delete'' part too which doesn''t even seem to exist in the man page for find. Anyone got a snippet that actually works? ;-) Sean -- Posted via http://www.ruby-forum.com/.

Both snippets seem to work just fine. Thank you! Sean -- Posted via http://www.ruby-forum.com/.

Makes perfect sense, too. Time to file a bug report on GNU find to add the multiplier suffixes. <grin> - Matt

(access vs. created) In other words, you probably want to delete stale session files that haven''t been used in a while rather than just deleting files that were created a while ago. Otherwise you risk dumping people''s sessions who frequent the site out from under them while they are in use. -- Posted via http://www.ruby-forum.com/.

Hi, I probably should have made this post a new topic. But is there a good way to clear sessions in general? Should one always rely on a cron job?

works for me:
class Cronjobs
def self.clear_sessions
Session.delete_all(["updated_at <= ?",
Time.now.yesterday.strftime(''%Y-%m-%d'')])
end
end
and then in your crontab:
20 0 * * *
/path/to/rails/app/current/script/runner
''Cronjobs.clear_sessions;'' -e
production
