if [[ -z "$TMUX" ]]; then
    tmux has-session &> /dev/null
    if [ $? -eq 1 ]; then
        shopt -q login_shell && exec tmux new
        exit
    else
        shopt -q login_shell && exec tmux attach
        exit
    fi
else
    TMUX_WINDOW=$(tmux display-message -p '#{session_windows}')
    if [ $TMUX_WINDOW == "1" ]; then
        shopt -q login_shell && run-parts /etc/update-motd.d/
    fi
fi

This script is designed to display an SSH banner when starting Tmux. It checks whether the TMUX environment variable is empty, which indicates that Tmux is not currently running. If Tmux is not running and the current shell is a login shell, it starts a new Tmux session. If Tmux is already running, it attaches to the existing session. If there’s only one window in the Tmux session, the script runs the /etc/update-motd.d/ script to show a message of the day for SSH sessions.
