when running "heroku logs", the logs id changed dractically.I want to show both old id and new log id – May 15 '12 at 08:03
I'm not sure of what you mean by the id changed but this might be due to new errors, if you want to see old logs see http://stackoverflow.com/questions/2671454/heroku-how-to-see-all-the-logs – Seb Cesbron May 15 '12 at 09:15

Try this command (select lines which starts with exception id):

heroku logs | grep -i "\(\@6ac06o8ho\)\|\(\@4bc06o8ho\)"

or try less specific (select lines which contain id):

heroku logs | grep -i "\(6ac06o8ho\)\|\(4bc06o8ho\)"

or this(same as above but filter through maximum of 1500 lines):

heroku logs -n 1500 | grep -i "\(6ac06o8ho\)\|\(4bc06o8ho\)"

Also i was suprised that it's possible to combine grep with --tail to filter logs in realtime:

heroku logs | grep -i "\@[a-z0-9]\{9\}"
