Indeed. Here's my two-liner. ARGV[0] is the base to be used, ARGV[1] is
the file to be processed.

p = /^[#{"0123456789abcdefghijklmnopqrstuvwxyz"[0...ARGV[0].to_i]}]+$/i
puts File.open(ARGV[1]).readlines.reject!{|l| l !~ p}

I do not reject words that contain digits. That would reject valid
Internet slang like "l8er" or "gn8", leetspeak like "1337" or "H4X0R",
and acronyms like I18N or L10N.
