David, The above prints only the unique lines. I, too, have used this after grep to remove duplicates. With the data referenced in this thread uniq will not do the job because either each line is unique as a whole (same date, same hour, different value) or considered a duplicate (same date, same hour, same value). The former removes nothing, the latter removes the value for 5:00 pm. The need is to replace only the second duplicated 16:00 hour with 17:00.
