You might have seen
screenfetch or similar tools like
bginfo (winblows only) before. But how to install them so that they provide constant use to every user on a system. Here is how i did it for my virtual consoles (text based pre login environment). Thanks to cron it runs every minute and updates the /etc/issue file, which is then displayed on every console.
apt install screenfetch -y
echo '* * * * * root echo "\l\n$(screenfetch)" > /etc/issue' >> /etc/crontab
screenfetchto your system wide bashrc /etc/bash.bashrc :
echo "screenfetch" >> /etc/bash.bashrc
