You may have to be more specific in stating your question if this doesn't satisfy your requirements.
If it's about filename, like Greg thinks, then I'd suggest
find . -type f -not -name \*.\*
command instead.
perl -MFile::Find -le 'find sub { print if -f and /[^.]/ }, "."'
This will look in the current directory and all subdirectories for files that don't have a period in them.
