Linux 使用mtime查找不'；行不通

我在家里做了一个文件夹，里面有一个文件。现在我正在执行

find /home -mtime 1

但它什么也没找到。这正常吗？

您需要使用：

find /home -mtime -1

根据

人工查找

：

-mtime n[smhdw]
    If no units are specified, this primary evaluates to true if the difference between 
    the file last modification time and the time find was started, rounded up to the next 
    full 24-hour period, is n 24-hour periods.

    If units are specified, this primary evaluates to true if the difference between the 
    file last modification time and the time find was started is exactly n units.

您必须根据需要将

+

或

-

添加到整数值中。系统无法理解默认情况下

1

是

+1

1

表示修改时间正好等于1天，而

+1

表示修改时间大于1天。linux中的1天是根据当前时间的24小时持续时间，而不是根据日期的差异。
