Check for files affected by Dropbox bug

dropbox_empty_files.sh

#!/usr/bin/env bash

# Dropbox apparently has a potential bug where files can be zeroed out.
# Description here:
# http://konklone.com/post/dropbox-bug-can-permanently-lose-your-files
#
# The script in that article to detect zero-byte files is pretty naive about
# files that normally would be zero bytes, so here's an improved version that
# ignores some common cases:
#   - Mac OS icons
#   - .gitkeep files
#   - lock files
#   - iOS thumbnail cache files
#   - Anything with a resource fork (old Mac OS PostScript fonts, AppleScripts,
#     etc.)
#
# DO NOT COPY AND PASTE THIS!!! There is a control character that probably
# won't come through correctly. Instead save the file and run:
#    bash dropbox_empty_files.sh
find ~/Dropbox -size 0 -not -name 'Icon
' -not -name '.gitkeep' -not -name '*-lock' -not -name '*.ithmb' -not -xattrname com.apple.ResourceFork
