# this script looks into /etc/cron.{hourly,daily,weekly,monthly} for
|
|
# scripts to be executed. The info about last run is stored in
|
|
# /var/spool/cron/lastrun
|
|
#
|
|
# concept similar to debian and redhat
|
|
#
|
|
# Changes:
|
|
# 1998 - Burchard Steinbild <bs@suse.de>, 1998
|
|
# initial version
|
|
# before 2001 - va@org.chemie.uni-frankfurt.de
|
|
# send an email with name of date-script instead of cron entry
|
|
# "Subject: cronjob@www - daily - FAILURE"
|
|
# (better one script for each date-sub-script)
|
|
# requires changes to /etc/crontab
|
|
# append > /dev/null 2>&1 to the line calling run-cons
|
|
# 2001-09-11
|
|
# updated to Suse 7.2 merged
|
|
# 2001-09-12
|
|
# changed FAILURE detection, until now all scripts with output
|
|
# had "failed", now only scripts with error status != 0
|
|
# have failed.
|
|
# 2001-09-13 - ro@suse.de
|
|
# merged with 7.3: call logger with exit value for scripts
|
|
# respect MAILTO as cron does
|
|
# use mktemp -d for all tmpfiles
|
|
# add variable to disable mail if all jobs returned 0
|
|
#
|
|
|
|
#
|
|
# Don't run jobs on laptops, that are AC-offline
