I need to match column 2 from both file, and if they match, append the value of column 1 from file b to file a so it becomes like this
file c
I have tried the following but to no avail
as I understand it, it should read column 2 of file b and store column 1 into the associated array of a, and then match with column 2 of file a, and if match was found, print the row of column a, and also append the array a value to the end of row. I now think I am definitely wrong . Sorry really newbie here. There is no error but as I tested it, it did print and append the output but it appends at the middle of the row and overriding the row value and also for all line in a.csv, it appends the same value, as if it did not match at all.
Many thanks for the kind helps gents!
