As far as I can see you need both because File.stat only returns the numeric ID.

irb(main):008:0> st = File.stat "."
=> #<File::Stat dev=0x50a951b9, ino=6755399441101867, mode=040755,
nlink=9, uid=14366, gid=10513, rdev=0x50a951b9, size=0, blksize=65536,
blocks=0, atime=2009-06-09 17:44:07 +0100, mtime=2009-06-09 17:35:03
+0100, ctime=2009-06-09 17:35:03 +0100>
irb(main):009:0> st.owned?
=> true
irb(main):010:0> st.uid
=> 14366
irb(main):011:0>

Kind regards
