Re: [CentOS] ls --author ?

I want a script to determine the owner of a particular file and then "sudo -u <thatuserid> <somecomand>". I ran across the --author option of ls but that does not seem to give me anything useful. It prints a short form of the filename without any other information at all. In fact, the output of ls --author is indistinguishable from that of ls by itself:

...

# ls --author htdocs/* htdocs/hlllogo.png # ls htdocs/* htdocs/hlllogo.png #

Is there a linux command that will return just the userid in a form that can be passed to sudo or do I have to parse ls -l <filename>?

stat -c %U filename

The stat(1) man page has format details; it's part of the coreutils rpm.
