    原来是因为crontab无法直接执行bashrc中的环境变量...

    写法没错的

    个人碰到过crontab唯一坑的地方是
    day of month 和 day of week都指定的话,是任意一个满足就会执行,而不是两个都满足才执行。

    Note: The day of a command's execution can be specified by two fields —
    day of month, and day of week. If both fields are restricted (ie, are
    not *), the command will be run when either field matches the current
    time. For example, ``30 4 1,15 * 5'' would cause a command to be run at
    4:30 am on the 1st and 15th of each month, plus every Friday.

    楼主运行crontab的时候最好把log输出到一个文件中....用于调试和记录--
