How to save current tmux session

To preserve your tmux session across reboots, you can use a combination of tmux and a tool called tmux-resurrect. tmux-resurrect allows you to save and restore tmux sessions, including the state of each pane and window.

Here are the steps to install and use tmux-resurrect:

1. Install tmux-resurrect:

   First, you need to install tmux-resurrect. You can do this by cloning the repository and adding it to your tmux configuration.

   git clone https://github.com/tmux-plugins/tmux-resurrect ~/tmux-resurrect
   

2. Configure tmux to use tmux-resurrect:

   Add the following lines to your ~/.tmux.conf file to enable tmux-resurrect:

   set -g @plugin 'tmux-plugins/tmux-resurrect'
   run-shell ~/tmux-resurrect/resurrect.tmux
   

   If you don't have a ~/.tmux.conf file, you can create one.

3. Reload tmux configuration:

   After updating your ~/.tmux.conf, reload the tmux configuration by running the following command inside a tmux session:

   tmux source-file ~/.tmux.conf
   

4. Save the tmux session:

   Before rebooting, save your tmux session by pressing the following key combination inside a tmux session:

   Prefix + Ctrl-s
   

   The default Prefix key is Ctrl-b. So, you would press Ctrl-b followed by Ctrl-s.

5. Reboot your system:

   You can now safely reboot your system.

   sudo reboot
   

6. Restore the tmux session:

   After the system reboots, start a new tmux session and restore the saved session by pressing the following key combination inside the new tmux session:

   Prefix + Ctrl-r
   

   Again, the default Prefix key is Ctrl-b. So, you would press Ctrl-b followed by Ctrl-r.

By following these steps, you can save and restore your tmux sessions across reboots, ensuring that you don't lose your work.
