# This file is Copyright (C) 1990 by Bill Aten
# Thanks to Bill Aten for this script.
# Run it AFTER MIDNIGHT so that date is correct!
# On our system, we have the following in our crontab:
# 02 00 * * * /usr/local/adm/remind-all >/dev/null 2>&1
# This script must be run by root. The -u option MUST be supplied
# to Remind, or a severe security hole will exist. Note that Remind
# must be compiled to support the -u option for this script to work.
# Also, the -r and -q options must be used.
# The following line gets a list of users for systems using SUN's
# NIS service:
# USERS=`ypcat passwd | awk -F: '{print $1}'`
# The following line gets a list of users by examining /etc/passwd:
USERS=`awk -F: '{print $1}' /etc/passwd`
# If neither of the above methods works, you must come up with some
# way of getting a list of users on the system
# Set the following variables as appropriate for your system
REMIND=/usr/local/bin/remind
MAIL=/usr/bin/mail
RM="/bin/rm -f"
REMFILE=/tmp/RemFile.$$
# Scan each user's directory for a .reminders file
for i in $USERS
do
HOME=`grep \^$i: /etc/passwd | awk -F: '{print $6}'`
if [ -r $HOME/.reminders ]; then
# echo "$i has a .reminders file." DEBUGGING PURPOSES ONLY
$REMIND -u$i -h -r -q -iremind_all=1 $HOME/.reminders < /dev/null > $REMFILE
