I have many files.
Files format as follows
- cccedddh.yyi
where
- ddd: 3-digit the day of the year
- yy : 2-digit year
Example: jplg0010.19i
The files consist of two fields. I want to print output as yyyy-mm-dd(or yyyy-mm-ddT00:00:00) mean (average 2nd values from files)
For example for file of jplg0010.19i
2019-01-01T00:00:00 5 (let's say mean value is 5)
or
01-01-2019 5
I could calculate mean.
awk '{ sum += $2; count++ } END { print sum/count }'
However, I didn't convert values into date format from filename.
How do I do it for each files and then print in one file?
