    問下版主，atime，ctime，mtime有什么區(qū)別？

1. man find
   
2. -atime n
   
3.               File was last accessed n*24 hours ago.  When find figures out how many 24-hour periods ago the file was last accessed, any fractional part is ignored, so to match -atime +1, a file has to have been accessed at least two days ago.
   
4. -ctime n
   
5.               File's status was last changed n*24 hours ago.  See the comments for -atime to understand how rounding affects the interpretation of file status change times.
   
6. -mtime n
   
7.               File's data was last modified n*24 hours ago.  See the comments for -atime to understand how rounding affects the interpretation of file modification times.

@lddlww
modification time(mtime)
當(dāng)該文件的“內(nèi)容數(shù)據(jù)”更改時，就會更新這個時間。 內(nèi)容數(shù)據(jù)指的是文件的內(nèi)容，而不是文件的屬性或權(quán)限。

status time(ctime)
當(dāng)該文件的“狀態(tài)”(status)改變時，就會更新這個時間。舉例來說，像是權(quán)限與屬性被更改了，都會更新這個時間。

access time(atime)
當(dāng)“該文件的內(nèi)容被取用”時，就會更新這個讀取時間(access)。舉例來說，我們使用cat去讀取/etc/man.config，就會更新該文件的atime了。
