mustachify.sh

if [ -z $1 ] || [ ! -f $1 ]
then
	echo "Usage: ./cmds [location of gif]"
	exit 1
else
	output=/tmp/mustache
	rm -rf $output
	mkdir $output

	echo "Extracting gif..."
	convert "$1" -coalesce $output/frame_%03d.png
	echo "...done."
	mv $output/* ~/Dropbox/Public/mustache/
	echo "Uploading to dropbox"
	#sleep 60
	read -p "Press [Enter] key to continue..."
	echo "Starting to mustachify..."
	for frame in ~/Dropbox/Public/mustache/*.png
	do
		name=$(basename "$frame")
		url="http://dl.dropboxusercontent.com/u/170196/mustache/$name" # My public Dropbox URL
		wget "http://mustachify.me/?src=$url" -O "$frame-stache" --tries=3 
		mv "$frame-stache" "$frame"
	done
	echo "... and done!"
	mv ~/Dropbox/Public/mustache/* $output/
