Dear Monks I have 6 files in which there is two columns per line. I want to compare the first column and each file filed by field, and get the maximum one, retrieve the second column value corresponding to the max value. for example if I have in my 6 files like this:
file1: 2 3 file2: 4 2 file3: -1 2 file4: -4 4 file5: 0 -1 file6: 0 -1
I want to retrive 2, since 2 is the value corresponding to 4 which is the max value of the first column and each file. Any idea what is the best way to do it?
