create a hash which has the keywords to watch for as its keys
foreach file (probably using File::Find) do
    open file (error check)
    foreach line in file
        split the line into fields
        is the first field from this line in my hash of important keywords?
            if yes, are there empty or dash fields in this line?
                if yes, report this file
                           (and keyword and/or line number, optionally)
                    and move on to next file
    end of lines
    close file
end of files
