Update: now uses -L (not -v) as that'll do the right thing (thanks to nite_man) 
# use -r if you want to process recursively
grep -L 'N\+' your_directory | xargs cp --target-directory wherever

Or a not-quite-one-liner in perl 
perl -MFile::Find::Rule -le 'print for find(file =>
grep => qr/(?!N\+)/, in => @ARGV)' sourcedir | xargs \
cp --target-directory wherever

They're untested and assume *nix-esque command-line tools (which should be fine since you're running linux) but that should get you started.
