Ranking data points from multiple files
I need to rank a large number of data points that exist in multiple files. My data points (Column 3) are based on unique values in columns 1 and 2. I need to rank the values that are in File 1, Column 3.

For instance:

Input File 1
Code:
AAA BBB 10
CCC DDD 16
EEE FFF 20

Input File 2
Code:
AAA BBB 11
CCC DDD 14
EEE FFF 19

Input File 3
Code:
AAA BBB 12
CCC DDD 15
EEE FFF 19

Expected output
Code:
AAA BBB 1
CCC DDD 3
EEE FFF 3

Any ideas how to best perform this analysis? I am familiar with awk and bash.

what's the math to calculate the rank (given the samples)?

I was using this script for ranking 1 column of a single file - In this case i was ranking column 4.


Code:
sort -k4 -n  file | awk '$4 != prev { rank = NR }{ print $1, $4, rank ; prev = $4 }'

But this new script needs to rank multiple files based on the same data points that are in columns 1 and 2.

You've told us how you don't want them ranked.

What we need is how you actually do want them ranked.

I would think that the awk variable NR would be able to count the number of records and create the rank based on that.

There are 2 stumping blocks for me:
1) I dont know how to make File 1 be the data value that it is ranking.
2) Im not sure how to best search for each data point (columns 1 and 2) in all the files. What is the most efficient way in doing this?

NR is the line number, effectively. AAA BBB should have a rank of 1, CCC DDD should have a rank of 2, etc.

If that's not what you do want, you'll have to actually tell us what you want instead of showing something which gives you things you don't want.

I have the following script that will search for a data point and return the sorted values.

How would I:

1) Create a variable for each of the data points that are in File 1
2) Create an additional column with the ranking of the values

Code:
for year in "${test}"/{1900..2016}05.pnt 
do
cat "$year"
done |
grep "AAA BBB" $year | sort -k4 -n

Code:
 
 AAA BBB    24.48
 AAA BBB    24.70
 AAA BBB    24.95
 AAA BBB    25.10
 AAA BBB    25.28
 AAA BBB    25.36
 AAA BBB    25.57
