Écran de démarrage du terminal avec météo, calendrier, heure et Sysinfo?

J'ai vu un Ubuntu Bash sous l'écran de démarrage du terminal Windows 10 ici: Sous-système Windows pour Linux afficher la distribution Linux?

WSL Bash screeny

Comment puis-je changer mon ~/.bashrc pour obtenir un écran de démarrage similaire sous Ubuntu classique, ressemblant à ceci ?:

Oui, c’est vraiment -14 à Edmonton et on se croirait à -23. Un bon moment pour passer le long week-end à l'intérieur du tout nouveau Tomb Raider 2013! Peut-être rafraîchir votre CV pour déménager à Vancouver ou à Montréal ...

Enregistrez les modifications du fichier `~/.bashrc".

Pour afficher les informations Ubuntu, vous avez besoin de screenfetch:

Sudo apt install screenfetch

Il existe des packages d'affichage similaires à screenfetch alors magasinez!

Si vous voulez la même commande Invite avec "─────────" ligne de séparation entre les commandes, modifiez ces lignes:

if [ "$color_Prompt" = yes ]; then
    PS1='───────────────────────────────────────────────────────────────────────────────────────────
${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='───────────────────────────────────────────────────────────────────────────────────────────
${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_Prompt force_color_Prompt

Notez que la longueur de la ligne de séparation coïncide avec la largeur de la sortie screenfetch. Dans ce cas, la largeur est de 92 caractères et les préférences gnome-terminal sont définies en conséquence.
