Listing 2: maxsize.rc -- Configuration file for maxsize.sh

######################################################
# maxsize.rc - this is the configuration file
# used by cron to keep files at a certain size.  If
# the file is greater than max lines, then lines are
# removed from the beginning of the file.  This is
# useful for mail outboxes and log files that
# otherwise grow over time.
#
# owner must have permission to edit the file.
