tmux

I'm switching from using gnu-screen to tmux, and I'm still trying to wrap my head around changes.

One thing I'd like to be able to do is start tmux and have it automatically connect to a session if one exists, and otherwise create a new session.

tmux attach attaches to an automatically existing session - but errors out if no session exists
tmux new creates a new session - but it does so every time, so I can't leave it in my .tmux.conf
tmux has-session tests whether a session exists - but I don't know how to stitch it together with the other commands

Can anyone give me some configure file advice?

Is there a way to create identifiable Byobu sessions so that when I've got multiple sessions running, the byobu-select-session menu gives me a list of sessions I can recognize, as opposed to non-descript tmux port numbers? In an ideal world, it would be great to be able to both start a session giving… >>> More

I'm not really clear with my question here, let me rephrase it : I've setup a launch_workspace.sh to launch directly tmux with 5 different commands loaded. Here is my current content : #!/bin/sh tmux new-session -d -s scube -n 'vim' "vim" tmux new-window -t scube:2 -n 'server' "$SHELL -c 'script/rails… >>> More
