Does this forum say “ruby on rails” anywhere? Or is it your
understanding that any forum that contains the words “ruby” or “rails”
could not possibly be related to precious gems or trains.
In the Ruby programming language, which is what this forum is about, you
could do something like this:
fnames = [“somefile.csv”, “anotherfile.jpg”]
fnames.each do |fname|
pieces = fname.split(".")
if pieces[-1] != “csv”
print "bad file: ", fname
puts
end
end

This is a rather weak check as it only tests the file name. Note, that
you can do this more easily:
ok = /.csv$/i =~ file_name
