I wonder what commands are supported by MB Pro firmware/bash.
I'm trying to download (with curl) json data and read it (with jq). Script works well with Linux. Any tutorial or alike available?

It's not bash here, it's ash
, sort of a "diet bash"
For commands, look (e.g.)

ash is rather close to bash. So when you are familiar with bash you should find a way.
curl and jp are not there. You can work with wget and awk for grabbing data from the stream.
Please don't have the idea to install additional packages. This will fill your flash storage and operation will stop.
Just a warning as some user thought they can install stuff as on their regular PC and had a hard stop after that

short and simple after some trial and error
Code: Select all
#!/bin/sh
#
#read solar and uv data from url file at json format
#download file from url
i=0
while true;
do
wget -q http://veikkola-saa.com/pws2/solardata.txt -O /tmp/mnt/data/scripts/solardata.txt
solar=$(awk -F, '{print $2}' /tmp/mnt/data/scripts/solardata.txt | cut -d':' -f 2)
uv=$(awk -F, '{print $3}' /tmp/mnt/data/scripts/solardata.txt | cut -d':' -f 2)
#awk -F tells to split with comma (,) take second/third dataset and then cut tells to take second part of string after :
#
echo "uv0 $uv"
sleep 2
echo "sol0 $solar"
sleep 180
done
