Hi all,

How could I replace the blank lines in my .txt data file? It has many
empty lines between groups of "text". In truth, the file is not a
well-formated one, in strict sense. I would like to change blank lines
for "special caracter", for example "$". I supose this is easy to do,
but is taking my time in such a way that I'm thinking about to do
manually.

   sed? Easiest if you have access to sed:)
      sed 's/^[ \t]*$/$/p' <infile >outfile
will replace each blank line with $\n. :) :)
if no sed can you script your editor to do it? :) :)
  I don't have debugged boundary corner problem safe way
to do it handy but it involves using the free function std::getline
from <string> header most likely.
