CentOS 7 Crontab 不执行，报错 /bin/sh: root: command no

使用CentOS7 执行定时脚本，结果提示报错：

/bin/sh: root: command not found

问题在于文件 /var/spool/cron/root ，中无需再写root。

修改之后的脚本：

[root@localhost cron]# crontab -l
*/10 * * * * perl /home/awstats/wwwroot/cgi-bin/awstats.pl -update -config=www.zbphp.com >> /sbin/null 2>&1

文件 /etc/crontab 全部内容：

[root@localhost ~]# nano /etc/crontab

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:

# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
