crontab -u //设定某个用户的cron服务，一般root用户在执行这个命令的时候需要此参数
crontab -l //列出某个用户cron服务的详细内容
crontab -r //删除没个用户的cron服务
crontab -e //编辑某个用户的cron服务
基本用法:
1. crontab -l
列出当前的crontab任务
2. crontab -d
删除当前的crontab任务
3. crontab -e (solaris5.8上面是 crontab -r)
编辑一个crontab任务,ctrl_D结束
4. crontab filename
以filename做为crontab的任务列表文件并载入
/*以下是多启动一个进程进行服务*/
crond start //启动服务
crond stop //关闭服务
crond restart //重启服务
crond reload //重新载入配置
--openwrt设置/etc/crontabs/root:
* * * * * echo "hello" >> /cron.txt
--每次做修改时使用crontab /etc/crondtabs/root
--crontabs/root文件下写的定时任务是多线程运行，不按顺序执行
Sed命令：
sed -n '/hello/p' cron.txt 查询hello关键字，打印相应行
sed '/hello/d' cron.txt 删除含hello的行，输出到屏幕（原文件没删除）
sed -i '/hello/d' cron.txt 直接修改原文件
--[[non-repeat任务]]--
* * * * * echo "flag non-repeat">> /cron.txt; sed -i '/sed/d' /etc/crontabs/root
--[[repeat任务]]--
--添加定时任务exam
echo "* * * * * date >>/cron.txt">>/etc/crontabs/root;flag >/dev/null 2>/
--删除定时任务exam
sed -i '/hello/d' /etc/crontabs/root
--修改定时任务exam
