# Usage: radacct-rotate [options]
#
# Compress and later remove old FreeRADIUS' radacct log files with "-YYYYMMDD"
# suffix. This script is provided by the freeradius package in Alpine Linux.
#
# Options:
# -C FILE Location of radacct-rotate config file (defaults to
# /etc/raddb/radacct-rotate.conf).
#
# -c DAYS Compress files older than DAYS (overrides option
# compress_after_days from the config).
#
# -r DAYS Remove compressed files older than DAYS (overrides
# option remove_after_days from the config).
#
# -d Run in dry-run mode (only print what would be done).
#
# -h Show this message and exit.
