Bash – Split Large Directory

If you have a directory with a lot of files/directories in it and need it to be smaller this block will help by grouping 400 files at a time into different sub-directories.

Bash

#!/bin/sh

# macOS
i=0; for f in *; do d=dir_$(printf %03d $((i/400+1))); mkdir -p $d; mv "$f" $d; let i++; done

#!/bin/sh

# macOS
i=0; for f in *; do d=dir_$(printf %03d $((i/400+1))); mkdir -p $d; mv "$f" $d; let i++; done
