用mtime查找不起作用

Question

我在家里制作了一个文件夹，我触摸了里面的文件。现在我正在执行

find /home -mtime 1

但它没有找到任何东西。这是正常的吗？

Answer 1

您需要使用：

find /home -mtime -1

根据man find：

-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. 

Answer 2

您必须根据需要将+或-添加到整数值。系统无法理解1默认为+1
