Script splits a large directory with many files into subdirectories, and makes soft links from the original files to the new split directories (for batch processing in parallel)

#!/bin/bash

i=0;
for f in /media/GTCoutput/*;
do
        d=split_$(printf %03d $((i % 5+1)));
        mkdir -p $d;
        bn=$(basename "$f");
        ln -s "$f" "$PWD/$d/$bn";
        i=$((i+1));
