Ja, es ist wirklich -14 in Edmonton und fühlt sich an wie -23. Eine gute Zeit, um das lange Wochenende im Inneren zu verbringen und den neu angekommenen Tomb Raider 2013 zu spielen! Vielleicht den Lebenslauf auffrischen, um nach Vancouver oder Montreal zu ziehen ...

Um die Ubuntu-Informationen anzuzeigen, die Sie benötigen screenfetch:
sudo apt install screenfetch
Es gibt ähnliche Ausstellungspakete, screenfetchum sich umzuschauen!
Wenn Sie dieselbe Eingabeaufforderung mit der Trennlinie "─────────" zwischen Befehlen wünschen, ändern Sie diese Zeilen:
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
Beachten Sie, dass die Länge der Trennlinie mit der Breite der screenfetchAusgabe übereinstimmt . In diesem Fall ist es 92 Zeichen breit und gnome-terminaldie Einstellungen werden entsprechend festgelegt.
