Build the alexbot firmware from the CLI. First redirect stderr to stdout — pipe to less; then redirect stdout to /dev/null
while true; do ./arduino --verify --board espressif:esp32:featheresp32 '/home/alex/Downloads/alexbot_firmware/alexbot_firmware/alexbot_firmware.ino' 2>&1 >/dev/null | less -p 'warning|error' ; done
