rm all regex files in system

# WARNING: This script will attempt to delete all files containing the
# string given to it as an argument. Do not run unless you know what
# you're doing. You should have already located every file with this
# string and decided that it can be deleted. This can easily break your
# system, especially if run as root. It creates a backup at ~/rmbackup.
# If run as root, that is /root/rmbackup
#
# There is probably a more concise way to do this with only one loop, but
# I didn't feel like figuring out how to fix the directory structure
# problems for the backup when you combine the loops as is.
#
# sh choosename.sh [regexp]
