How to Determine the file owner's username

I've read the following post here and I get no output from the command. I've tried changing the '$3' to $5, 7, 10...and still nothing. Ultimately what I'd like to is determine who owns the file and rename it to file_name_$USERNAME.

$ uname -a
SunOS sun001 5.10 Generic_118833-33 sun4u sparc SUNW,Sun-Blade-1500

Thanks! (in advance)

$ ls -l myfile
-rw-rw-rw-   1 myuser mygroup       43 Jun  4 19:40 myfile
$ ls -l myfile | awk '{print $3}'

Assming there is only one file. The technique would be different for multiple files.

USERNAME=`ls -ld "file_name"|awk '{print $3}'`
mv file_name file_name_${USERNAME}

Thanks to all whom replied, the other posting simply had the layout transposed.
