This is the script used for the May 19 (day 8) data collection:
files=`ls *.gps | cut -d. -f1` files=`ls *.gps | cut -d. -f1` for file in $files do awk -f awkhold $file.gps $file >> day8gps.txt doneThe script not only parses the GPS navigation, but concatenates the results into a single file. This script was repeated for days 9, 10, and 11 (May 20, May 21 and May 22 respectively) with the output directed to day9gps.txt, day10gps.txt, and day11gps.txt. For the September cruise, the output files were sept2208gps.txt, sept2308gps.txt, sept2408gps.txt and sept2508gps.txt.
