Restore Tmux Sessions After Reboot

OK, we see how we save and restore our sessions in tmux. Look at this article: Restore Tmux Sessions

But after rebooting the system how can we start the saved sessions? Here what I was doing before:

• To restore sessions after reboot I run:

  $ tmux new-session

• Then I hit prefix + ctrl-r

This restores all of my sessions and windows, but it also leaves me with the
"extra" session that was created with new-session.

• I kill this new session. This drops me out of tmux and back to the default terminal. Then I have to run:

  $ tmux attach

Now I'm finally in my restored session without the "extra new-session".

You see it is a real pain. For every reboot. For. Every. Reboot.

For lazy developers like us, there is always a "one-line" or "one-click" or "one command" solution. Thanks for github there were some alternatives and found mine: github solution.

alias mux='pgrep -vxq tmux && tmux new -d -s delete-me && tmux run-shell ~/.tmux/plugins/tmux-resurrect/scripts/restore.sh && tmux kill-session -t delete-me && tmux attach || tmux attach'

I had to tweak this code a little bit since -q flag throws an error. Also I
made it more readable.

alias mux='pgrep -vx tmux > /dev/null && \
        tmux new -d -s delete-me && \
        tmux run-shell ~/.tmux/plugins/tmux-resurrect/scripts/restore.sh && \
        tmux kill-session -t delete-me && \
        tmux attach || tmux attach'

OK, now it is a "one command" solution.

Hello Serhat, good stuff!
However I am getting an error when I use "mux" as command.
"~/.../tmux-resurrect/scripts/restore.sh" returned 127

I am using Fish shell, not sure if that's an additional problem for tmux.
