I made a mistake when writing an awk script that inserts the time of an observation with its value. I had 16:00 twice in a row rather than 16:00 and 17:00. This holds for every day in the year, and I have about 12 year's in which to make the correction. Specifically, changing the second 16:00 to 17:00. A sample:
2012-10-01,16:00,297.94 2012-10-01,16:00,297.94 I'm stuck trying to find a way to make the change using sed, awk, or grep. How do I ignore the first instance and change only the second instance? If there's a perl script to do this, please share it with me as I'm not a perl coder. I'm looking forward to learning how to do this job.
