Cron工作由邪魔处理命名 crond. 当增加，删除或者crontab时修改cron日程表，所有变动由crond邪魔立法。 Crond恒定邪魔奔跑在背景和检查中，一旦一分钟看见其中任一个预定的工作是否需要被执行。 若有的话， crond将执行命令。 如果crond过程不跑， cron工作不会被执行。

    I have cron daemon running and I added an entry using crontab -e command. When the exact time reached, the script that is specified is the crontab did not get executed.

    But, if I restart the cron daemon (using the command /etc/init.d/crond restart) after adding the cron entry (using crontab -e command), then the script gets executed at the specified time.

    When I looked at the man page of crond, they have clearly mentioned that, it is not required to restart cron daemon everytime the cron entries are updated. Am not sure whether I need to start the cron daemon with specific parameters so that it does not need to be restarted every time I update the cron entries.

    Any help is appreciated.
    Thanks & Regards
