Question

我有几个cron作业每天从我的cPanel运行。这意味着99％的时间我收到每日电子邮件说一切正常 - 备份没问题，xml导入正常等等。

但我需要的是当cron的结果不正常时的通知 - 即不正常。我已尝试在Outlook中制定规则，但我无法使其发挥作用。

这是我的一个朋友：

30 2 * * * /usr/local/bin/php /home/xx/public_html/administrator/xx/xx/backup.php -profile=1  -description="Backup"

我知道'Bash'有可能，但不是如何实际使用它。

任何人都有好主意吗？

您可以在作业周围编写一个包装器，并从cron中调用包装器。

示例：

#!/usr/bin/env ksh

#
# Wrapper around a backup script.
#
# Redirecting all output to a log file
# In this case to /home/xx/public_html/administrator/xx/xx/backup_job.log

#
# Lets log the start date of the job in a log file
#
echo "Starting backup job at `/bin/date`" >> /home/xx/public_html/administrator/xx/xx/backup_job.log

#
# start the backup
#
/home/xx/public_html/administrator/xx/xx/backup.php >> /home/xx/public_html/administrator/xx/xx/backup_job.log

#
# The backup job should have set a return value (0 or non-zero).
#
# If it is non-zero then there was an error. Lets send a warning mail about it
# 
#
if [[ $? -ne 0 ]]; then
 /bin/mail admin > /var/adm/backup_log

#
# Exit with a 0 value. That should indictate that this job (the wrapper) worked fine
# Usually this means cron does not have to send a mail. (But then, we already took care 
# of warning mails on our won if there was an error
#
exit 0
