DOM

  • ¿Qué es el DOM? Document Object Model

  • ¿Qué es un selector? Nos permite encontrar uno o más elementos HTML

  • ¿Cuál es la diferencia entre document.getElementById y document.getElementsByClassName? Además de que regresan elementos por distinto selector, el Elements regresa especificamente un arreglo, así devuelva un sólo elemento dentro.

Takes all jpgs from the source folder and copies only the jpgs that present a significant difference, used to remove repeated frames from webcams output.
#/bin/bash
#We only allow empty destination folders.
if [ -d "$2" ]; then
echo "Directory already exists"
exit
fi
#If it doesn't exists create it.
if [ ! -d "$2" ]; then
mkdir $2
fi
