A quick script to clean up image file names by removing blank spaces, capitals, redundancies, and adding authorship. It then creates thumbnails and xml entries for later use

make_lazy.sh

#!/bin/bash
# Super lazy way to get all the thing together to add
# more wallpapers to the SwagPapers (or similar) apps.
#
# USAGE: ./make_lazy $AUTHORS_NAME $FIELD_TO_REMOVE
# FIELD_TO_REMOVE is useful when the original author has
# added an aokp prefix to the image. We already know this
# will be an aokp related image, and is unneeded.
# Currently supported formats are .png and .jpg.
#
# In addition to most normal linux apps, this script will
# require the ImageMagick suit for thumbnail creation.
# You can find it here http://www.imagemagick.org/script/index.php

# first, make sure there is an author being added. If not, things
# break
if [ ! "$1" ]; then
    echo "author prefix not defined."
	echo "this is necessary for the script to run. Exiting..."
	exit 0

# nuke blank spaces
rename 'y/ /_/' *

# make all folders and filenames lowercase
# first, rename all folders (lazy kang from another one of my scripts)
