Using a text file to sort another file
Hi,

I have two tab delimited text files where the first columns match. I want to sort the second file using the first file, such that the first column of the second file is in the same exact order as that of the first file. I want to keep the ordering of the first file intact in the process. How do I go about doing that? Thanks!

Thanks. How would I alter the code, if the input files had more than 2 columns?
