I am having a strange problem about ubuntu crontab here.
If I add the following line to system crontab(/etc/crontab), it works well
*/1 * * * * root /bin/date >> /root/text
but if I edit root crontab by using
crontab -e with root user, and add
*/1 * * * * /bin/date >> /root/text
it does not work at all.
Can you please help me on this?
update and answer
I got my answer after searching server fault, the reason is explained in this post.
The reason is that crontab file need a newline in the end, otherwise it will not work.
