# listidle goes through all your users in your glftpd users directory,
#   and finds all the users that have not logged in for over $DAYS days.
# If you want to implement this as a script that can be run from inside
#   glftpd, for example SITE LISTIDLE, put these lines in glftpd.conf:
#       site_cmd LISTIDLE       EXEC    /bin/listidle.sh
#       custom-listidle         *

# Path to your userfiles. If using this program standalone, should be full
# path including rootpath. If you want to implement it as SITE LISTIDLE,
# should be relative to the glftpd rootpath.
USERPATH="/ftp-data/users"

# Warn about users who have been idle for more than this number of days.
DAYS="21"
