Ignore node_modules/bower_components folders in your Dropbox

DropboxIgnore.md

This script scans your Dropbox (or any given folder) for folders stored in the ignore array and excludes them from syncing. Makes use of the official Dropbox CLI

I'm a beginner at bash, so all improvements are welcome!

#!/bin/bash

set -e

# SETTINGS

dropbox_script="~/bin/dropbox.py"
