There is a tmux plugin for this.
Check out tmux-resurrect
Restore tmux environment after system restart.
Tmux is great, except when you have to restart the computer. You lose all the running programs, working directories, pane layouts etc. There are helpful management tools out there, but they require initial configuration and continuous updates as your workflow evolves or you start new projects.
tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart (or when you feel like it). No configuration is required. You should feel like you never quit tmux.
Features:
- continuous saving of tmux environment
- automatic tmux start when computer/server is turned on
- automatic restore when tmux is started
