First, I don't see "," in your input file.
Second, Do you mean the big file has been sessioned or sorted by column 1
For example, if column 1 is VTLJ.J, and after I see BKLJ.J, there should be no line with VTLJ.J.
You need confirm it first.
If it is not, you have to wait until awk go through the whole file, then gzip the output files.
