B4J Code Snippet Raspberry Pi run Bash Script

An example of running a Bash Script on a Raspberry Pi using the jShell Library.
The Bash Script runs several commands which create output files. The content of these files are send to Home Automation solution.

#Bash Script rpiinfo.sh

#/bin/bash
#Note:
#do not forget to x after change: sudo chmod a+x rpiinfo.sh. Then run ./rpiinfo.sh (to test prior using jShell Library)

#Get CPU Temperature - divide by 1000 in the B4J application
cat /sys/class/thermal/thermal_zone0/temp > rpicputemp.inf

#Get Disc space used
df -H | grep 'root' | awk '{ print $5 }' > rpidiscspaceused.inf

#Get RAM used
free -o -h | head -n2 | tail -n1 | awk '{print $3}' | tr -d [=M=] > rpimemused.inf

#Get RAM free
free -o -h | head -n2 | tail -n1 | awk '{print $4}' | tr -d [=M=] > rpimemfree.inf
