What I saw how access times of a file and directories work.
1) For a file the access time is the time when I 1st access it after last modification of the file, i.e., if the file is modified at 10 AM and then I access it at 11 AM. After than whenever I access without modifying the file the access time remains same as 11 AM.
while copying a file also the access time doesn't change!! Am I right? What's then the significance?
2) For a directory I had the same experience.
If I don't get the latest time when I accessed, then what's the significance of this type of behavior.
What filesystem mount options are you using? "noatime" is a commonly used one to improve filesystem performance. It improves performance by not recording the access time.
I am attaching the output of the commands you have told.
notime command hasn't worked.
Also, how to understand from the output that the feature of updating access time on accessing a file is disabled.
