Why do access dates change after mv'ing a file

[DarinGowan]

env: AIX 4.3.3
Alleged issue: Access dates change when I rename (mv) a file.

Question: Why does this happen? HP-UX does not do this. Is there an option, or fix that addresses this issue?

Problem: I want to maintain true "last update" date/time on files. I now have backup copies of files with the same date/time stamp as the newly updated file.

Does anyone else have this problem? I hope there is a fix for this...

Thank you kindly :?)

I never noticed that it behaves differently on HP, but you're right.

Here's what you have to do on AIX: cp -p <filename> /newpath/filename.

This preserves the timestamp and ownership. then you would have to do a rm <filename> to finish the &quot;mv&quot;.
