I am running the below bash loop on all the files of a specific type (highlighted in bold) in a directory. There are 4 awk commands that use the input files to search another and look for a match. The input files range from 27 - 259 and are a list of names. The file that is searched is 11,137,660 lines. The loop does run, however, it takes ~20 hours to complete on a computer with 64GB and a xeon 8 core processor. Is this normal and can it be made faster (more efficient)? Thank you .
