# Script to replace characters in filenames | September 2011 | r3dux
# Note: This script will work on files in the present working directory only.
# The script switches are:
#
# -t – turns on [T]esting mode, which displays what would happen if you ran the script, but makes absolutely no changes to filenames.
# -u – converts all [u]nderscores to spaces.
# -s – converts all [s]paces to underscores.
# -l – converts all filenames to [L]owercase.
# -p – converts all filenames to u[P]percase.
