A Ruby script to extract WordPress uploads without resized images.

wpmediaexport.rb

#!/usr/local/bin/ruby -w

# A Ruby script to extract WordPress uploads, excluding resized images, into a single directory.
# File names will be prepended with the directory #string.

# RUN: ruby wpmediaexport.rb >> wpmediaexport.sh
# THEN REVIEW/RUN: ./wpmediaexport.sh

# Generated shell script will be in wpmediaexport.sh.
# Cd into the uploads directory in WordPress before running.
# Make sure you create an empty img directory prior to running wpmediaexport.sh
# wpmediaexport.sh needs permission to run, thus you might need to run chmod +x wpmediaexport.sh.
