What this script does:

Update repos

sudo apt-get update && sudo apt-get -y upgrade

Install additional packages like Figlet, Lolcat and Neofetch

sudo apt-get install -y figlet lolcat neofetch

Figlet is an application which can gegerate ascii-art-like logo's from text_ Lolcat will add rainbow colors to your output Neofetch generates a nice ascii sysinfo

Download additional Figlet fonts

git clone https://github.com/xero/figlet-fonts
mv figlet-fonts/* /usr/share/figlet/ && rm -rf figlet-fonts

Generate Wortell Enterprise Security ascii logo with Figlet and add some color with Lolcat

/usr/bin/figlet "Wortell" -f larry3d -w 140 | /usr/games/lolcat -f -p 6 -S 47 >> wortell-figlet.txt
/usr/bin/figlet "           Enterprise Security" -f small -w 140 | /usr/games/lolcat -f -p 6 -S 47 >> wortell-figlet.txt

Notice how two different fonts are used. The logo is stored in ~/wortell-figlet.txt

We won't be needing these MOTD modules anymore...

sudo rm /etc/update-motd.d/00-header
sudo rm /etc/update-motd.d/10-help-text
sudo rm /etc/update-motd.d/50-landscape-sysinfo
sudo rm /etc/update-motd.d/50-motd-news
sudo rm /etc/update-motd.d/80-livepatch

...we're building new ones

Create new 00-header file with the ascii logo

Set HOME variable because that's where the ansi art resides

HOME=~

And add the appropriate lines to the 00-header

echo '#!/bin/bash' >> 00-header
echo 'cat '"$HOME"'/wortell-figlet.txt | /usr/games/lolcat -f -p 6 -S 47' >> 00-header
echo 'printf "\n"' >> 00-header

Create 01-neofetch for sysinfo

Nothing special just disabling Neofetch color blocks because it looks better IMHO

echo '#!/bin/bash' >> 01-neofetch
echo '/usr/bin/neofetch --color_blocks off' >> 01-neofetch

Create 02-weather for real-time weather report

We want a weather report based on the location of the server. So let's first find the local city

First we found our public IP then we find the local city based of that IP

CITYquoted=$(curl -s https://ipvigilante.com/$(curl -s https://ipinfo.io/ip) | jq '.data.city_name')

The string contains leading and trailing double quotes, we need to remove these

CITY="${CITYquoted%\"}"
CITY="${CITY#\"}"

And create 02-weather file

Note that the "m" make sure we get our results in metric. Check https://wttr.in/:help for more info

echo '#!/bin/bash' >> 02-weather
echo 'printf "\n"' >> 02-weather
echo 'curl wttr.in/'"$CITY"'?m0 --silent --max-time 3' >> 02-weather

Move the MOTD modules to their correct location

sudo mv -t /etc/update-motd.d/ 00-header 01-neofetch 02-weather

And make sure these new modules can be executed

sudo chmod +x /etc/update-motd.d/00-header
sudo chmod +x /etc/update-motd.d/01-neofetch
sudo chmod +x /etc/update-motd.d/02-weather
sudo chown root:root /etc/update-motd.d/*
