Power best practice please
I have a data file that I tail and dump the data into a new file at midnight.
To work I had to use tail -n2 livefile.csv >> storefile.csv. This is ging me 2 or 3 entries at a time into the storefile.csv.
if I continue this then I will have to run a second pass on the file to remove the duplicates from the csv file. all the files start with the date.
I only need one entry per night.

What is the best way to do this ? I have 6 files to do this to each night.

Thank you

Mike
