# Script to locate world writable files.
# The find command ignores /proc files, /dev files
# (hundreds of these are correctly world writable),
# Symbolic (soft) links (which should have mode 777),
# directories with the sticky (save text) bit on, and
# sockets, as that is relatively safe. Note that
#/dev should be cleaned out so that this script can
#look there too.
