Using jq
Command to return the id number of the last scan:
cnt=$(jq '.lastVehicleRecord.scans | length' heartbeat)
Fancy way to find the scanId of a selected system via bash and jq
if [ -z $1 ]; then whichIE="uvx"; else whichIE=$1; fi
printf ".lastVehicleRecord.scans[] | select(.type | endswith(\""$whichIE"\"))\n" > parms.jq
wget -qO heartbeat http://$ip/heartbeat
cnt=$(jq '.lastVehicleRecord.scans | length' heartbeat)
id=$(jq -f parms.jq heartbeat | jq '.id')
if [ ! -z $id ]; then
wget -qO $id.orig.tiff http://$ip/requestImage/?scanId=$id
fi
