linux ext2有4个mac time codes

> M – 修改
> A – 访问
> C – 创建
> B – 不适用

怎么可能是“不适用”?这是什么意思?

解决方法:

这只意味着没有b标志的等价物,例如无法为特定文件系统翻译它.

b可能代表记录文件创建时间的出生时间.Wikipedia article about MAC times提到了Windows和Unix之间的区别,并且还介绍了出生时间这个术语:

• Unix systems maintain the historical interpretation of ctime as
being the time when certain file metadata, not its contents, were
last changed, such as the file’s permissions or owner (e.g. ‘This
files metadata was changed on 05/05/02 12:15pm’).

• Windows systems use ctime to mean ‘creation time’ (also called
‘birth time’) (e.g. ‘This file was created on 05/05/02 12:15pm’).
