[求助] 关于crontab文件命令不能执行的问题?

bst

47  17 * * * /root/bin/a.sh

这个是我的crontab文件的内容 a.sh 只有一句 clear

到时间后a.sh 不自己执行而是通过crond 发了个邮件给我a.sh在邮件里边打开执行了.

郁闷! 谢谢了.

The clear command is used to clear screen from your working console or terminal, more precisely, your standard output.

I suspect the std-out is not defined so that even when a.sh is executed, you are not noticeable but only alert by crond.

Try to replace the clear command with others and see if it works.
