I have a tab-delimited txt file that contains my data with many columns and lines. Here, to explain my problem I'm using a dummy file.
This file has some columns. I want to perform the following action serially;
-
Sort data file based on the value of columns A and B. This step may generate two sorted copies of my original data but, these files are not mandatory.
-
Then I want to extract the top five data from each sorted copy and generated two files (as for example; TopA, TopB).
-
You may notice, these files contain some common numbers in the first (Pos.) column. Here, in the example number 302, 941 and 699 are common in Pos. column of all files (TopA, TopB). Thus, my target is to extract only those data which contain a common number in Pos. column in all files and save them in result.txt file.
Table of Contents
Would anyone please help me with a bash/perl/python code to get this result?
Thanks in advance.
