Add Message of the day to RPI

Recently I wanted to add a message of the day (MOTD) to my RPI. Basically every time I login i want to see the some info as shown in the picture.

The way how to do that is to add some code to the “~/bash_profile” file, so it is executed when an interactive  login shell is launched (like when you ssh into it).

I found one example on the RPI website, but was showing the temperatures in “Fahrenheit” degree!  So i quickly changed that to show the degree in “Celsius”. So I fixed few other things in the script (such as locations) but it was still failing to get the temperature! After some quick debugging, i discovered the the regex in the “SED” function was not parsing the minus sign in front of the weather forecast string (And in Oslo we are often below 0*C). So I fixed also that..  Here there is the final code.. Just append it to you “~/bash_profile” and should work…

let upSeconds="$(/usr/bin/cut -d. -f1 /proc/uptime)"
let secs=$((${upSeconds}%60))
let mins=$((${upSeconds}/60%60))
let hours=$((${upSeconds}/3600%24))
let days=$((${upSeconds}/86400))
UPTIME=`printf "%d days, %02dh%02dm%02ds" "$days" "$hours" "$mins" "$secs"`

# get the load averages
read one five fifteen rest < /proc/loadavg
