How can I delete every third AND fourth line in a file?
cat test.nmea|awk 'NR%3!=0'
This deletes the 3rd line, or I can delete the fourth but I can't figure out how to delete the 3rd and 4th together. I'm looking for a quick way to make a GPS log half its size.
Also how do I pipe the output to another file?
Hope someone can help!
