Bash One-Liner for Getting Arduino Serial Data to Stdout

Have the data go directly to stdout, or you can send it to a file, and monitor it. Timestamping and triggers can be set within the `awk` portion

to stdout ```bash cat /dev/cu.usbmodem1421 | awk '{ for (i=0; i<NF; i++) printf $i + system("date +,%s")}' ```

this will say "ITS OVER 9000!" when the data increments. ``` cat /dev/cu.usbmodem1421 | awk '{ for (i=0; i<NF; i++) if($i == 9001) {system("say ITS OVER 9000\!")} printf $i + system("date +,%s")}' >> sensor_readings.dat ```

Just remember to change the `cu.usbmodem1421` to your arduino's serial port, and fire away!
