1、crontab crontab文件用于在指定日期和时间周期性地执行作业 crontab 作业存放在/var/spool/cron/crontabs/$USER cron根据crontab文件项运行命令。如果用户不指定将cron作业的输出重定向到标准输出或标准错误。 cron将使用电子邮件向用户报告其输出或错误 要使用cron，用户必须建立crontab文件 cron进程将crontab文件驻留在内存中，所以用vi直接修改硬盘上的cron文件是没有效果的 必须使用crontab命令操作，它会告诉cron进程crontab文件已修改 语法： minute hour day month dayofweek command 分钟 小时 天数 月数 （0~6，0表示星期日） 示例1： 50 23 * * 6 /home/oracle/rman.sh 表示每月每天的23点50分，只要这一天星期六，就执行脚本 50：表示50分钟 23：23点 *：表示所有天 *：表示所有月 6：表示星期六 在AIX中，任务计划的使用授权控制在两个文件中： /var/adm/cron/cron.deny ：定义了不允许使用cron的用户 /var/adm/cron/cron.allow :定义了允许使用c'ron的用户 如果两个文件都存在，那么只有cron.allow文件有效，如果两个文件都不存在

Quite simply, I have node script that I want to execute once a month. 30 6 1 * * node /home/steve/example/script.js But this doesn't work, presumably because of path or the shell the command is being ran under.
