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
More interesting jq examples:
"plateCoordinates":[898, 210, 144, 44] "plateCoordinatesRelative":[898, 210, 144, 44],
jq ".plateCoordinates | .[1]" upload_test/2023-05-12_12:08:07.txt
Tiff info parsing
