I had to reboot my box today. I had several program running in tmux sessions. They seem to be still alive, how can I reattach to them? I tried tmux a processID but it didn't work.

When you detached from tmux and want to reattach to it again you use the tmux attach command. Without any argument this command reattaches tmux session that was the latest one to be detached. attach is a shorthand actually for attach-session , but both do the same thing so you can use them interchangeably.
Detach From A Session To detach (meaning exit the window to come back to later) from the tmux session, use CTRL + b then d (hold ctrl, press b, let go of both of the keys, and press d). Whatever program(s) you are running in the tmux session will continue going without you.
First, you press Ctrl+B to get tmux 's attention. You then quickly press the next key to send a command to tmux . Commands are given by pressing letters, numbers, punctuation marks, or arrow keys. It's the same in screen , except you press Ctrl+A to get its attention.
You can not re-attach a process id. You need to reattach the corresponding tmux session.
So do tmux ls. Pick whatever session you want to re-attach. Then do tmux attach -d -t <session id> to re-attach it to a new tmux instance and release it from the old one.

If you only have one session detached you can just do
tmux attach also if you're going to be working in multiple sessions it might be a good idea to name your sessions
tmux new -s ssh-to-staging Ctrl b, d # Detach from session tmux new -s ssh-to-s3 Ctrl b, d Detach from session now when you do tmux ls you can reattach more easily without guessing.
tmux attach -d -t ssh-to-s3 You also might wanna bookmark this cheat sheet
