What is noatime + nodiratime ?

I have tried searching google, the forums, etc... but I haven't really found out to much about what noatime and nodiratime do.

If someone could enlighten me that would be great!

Thanks!

man mount
/atime
n : next
N : prev
(btw you can use the same keybindings in vim)

Do you need to know more than this description?

Thank you. I did not think to look at mount, I did check fstab though

So that basically is saying that it doesn't update the file access time, correct?

I believe that's right. It's a bit overkill as I understand it though, since even cached adjustments get updated on the drive. This quote makes me laugh:

It's also perhaps the most stupid Unix design idea of all times. Unix is really nice and well done, but think about this a bit: 'For every file that is read from the disk, lets do a ... write to the disk! And, for every file that is already cached and which we read from the cache ... do a write to the disk!'

And yes, last time I checked, setting noatime gave you nodiratime too. But the reverse of that is not true.
