Bonus guide: System overview

Difficulty: easy

To get a quick overview over the system status, I created a shell script that is run as “message of the day” (motd) to be shown on login or on demand.

MotD system overview

This script will run as root, so please check it before blindly trusting me.

$ sudo apt-get install jq net-tools
$ cd /home/admin/download/
$ wget
# check script & exit
$ nano 20-raspibolt-welcome

# delete existing welcome scripts and install
$ sudo mv /etc/update-motd.d /etc/update-motd.d.bak
$ sudo mkdir /etc/update-motd.d
$ sudo cp 20-raspibolt-welcome /etc/update-motd.d/
$ sudo chmod +x /etc/update-motd.d/20-raspibolt-welcome
$ sudo ln -s /etc/update-motd.d/20-raspibolt-welcome /usr/local/bin/raspibolt

In case the script runs into problems, it could theoretically prevent you from logging in. We therefore disable all motd execution for the “root” user, so you will always be able to login as “root” to disable it.

$ sudo su 
$ touch /root/.hushlogin
$ exit

You can now start the script with sudo raspibolt and it is shown every time you log in.
