#!/bin/sh

# parse.sh is a shell script for creating the input file in necessary
# format for the programs included in EmoDetect. This shell script
# recursively goes through all subdirectories, and lists all .jpg files
# along with a label to indicate the associated emotion. This file has been
# optimised to work with the MUG facial expressions data set mentioned in
# the README. This file may need to be changed if another data set is used.
#
# Shell script to find out all the files under a directory and its
# subdirectories. This also takes into consideration those files or
# directories which have spaces or newlines in their names
