1) I have a requirement where in I need to find and sort files user wise in a folder. The files can be situated in any subfolder that may also be hidden.
The files then need to be sorted according to size and date of creation.

2) Can we find out files for users who's entry is not there in /etc/passwd.

You can use sort and ls command to do the task. Are you on solaris or linux? Then I can give you command

All users must have entry in /etc/passwd.. then users can login in and create files. So some sort of user always needed to create file ownership.

I am working on Solaris 9.0
Can I use sort for the any field.
I have seen many files that are situated somewhere on the system and are owned by users who's IDs are either deleted or suspended. Can we find out these files by comparing the user validity in /etc/passwd.

Oh ok I got it your question, here is what you need to do:
You can pass the -nouser -nogroup option to find command:

Display list of files/dirs where user/group does not exists in (user) /etc/passwd (group) /etc/group file
Or better find out all files/dirs and save all such files to nouser.txt file
Let us come to sorting question
Use ls command, under solaris the output is sorted alphabetically by default.
No UNIX and Linux OS stores the date of creation. They only stores the access/modification time so you cannot find out date of creation, however you can get the last accessed/modification date/time stamp via ls -c command.

If you have a GNU find command then you can also try following else use above command on Solaris:

thanks,
agreed...but can I sort ...say ...the output of ls -al, user wise and then save file entries for every user in a seperate file..so I can have disk usage status of every user in that folder.

this would be a great help....

ganesh.

cant u use ls command?

ls -al | sort -n +{FIELD}
