ITerm 2 now offers deep tmux integration

Discussion on this from yesterday: http://news.ycombinator.com/item?id=3498163

This feature list is getting bookmarked as one of those "EXACTLY WHAT I NEEDED" moments. I hope the iTerm folks had as much joy writing it as I see imagining my new fabulous and easy life managing remote shells..

explain tmux for the noobs?

like screen but better

I don't know tmux, but I know Screen, and they're supposedly very alike.

Simply put, it's a persistent shell. If you SSH into a server, kick off a long running job, and get disconnected, it depends on a lot of factors whether or not that job completes. Generally though, you can consider yourself screwed.

Instead, if you connect to a server via SSH, then launch screen, the session is pushed or persisted to the server. You get disconnected, and you can log back in to the server via SSH and reattach to the screen. Any jobs you kicked off are still running, and you're returned exactly to where you were before you were disconnected.
