Having
UNIX Requirement as a thread title gives us no indication of what you are trying to do. In the future, please select a title that gives people scanning threads some idea of what topic is being discussed.
If you look at another thread that was started about a week ago (
Bash directory loop and order by creation date?), you'll see that this topic has already been discussed in detail. There is a high probability that what you want is not available on AIX, and since you still haven't told us what filesystem type you're using, there is no way for us to make any attempt to determine if the files on the filesystem you're using have a file creation date timestamp.
Our crystal balls cannot clearly see through your posts to determine the information we need to be able to tell you that the information you want is definitely not available; or if it is available, tell you how to get it. If you don't answer our questions or read the manuals on your own, there is no way for us to guess at how to satisfy your requirement or even if it is possible to satisfy your requirements.
