list of file owners in folder on linux

I have a folder with many files. The files have been created by many different users. I do not know about shell scripting.

I need to get the list of the username (only) of the owners of the files.

I may save the output of ls -l and then parse it using perl python etc...

But how can i do this using shell scripting?

The two solutions so far are good, but have their limitations.

This should guarantee you properly and recursively search every file in a directory tree.

sudo find /some/dir/ -exec stat -c "%U" {} + | sort | uniq

In other words, recursively search for files in /some/dir, and execute stat -c "%U" (print username) on the files, in as few invocations of stat as possible (-exec <cmd> {} + syntax), then of course sort the list of usernames, and in turn cull them to just the unique set of usernames.

To limit the search to just regular files, then add the -type f clause:

sudo find /some/dir/ -type f -exec stat -c "%U" {} + | sort | uniq
                     _______

A simple one is

ls -l /some/dir/some/where | awk '{print $3}' | sort | uniq

which gets you a unique and sorted list of owners.
