Hi
short question:
I want to replace \n also:
gsub(/\na/sg,"A")
What is wrong ?

Thx Berg

Should work:

    irb(main):001:0> "foo\nbar\nbaz".gsub(/\n/, ' ')
    => "foo bar baz"

If it doesn't for you, could you please copy the exact string and code
you're using?

Hi
the problem was another: ruby -p

what is best to do that (with ruby -i ...) ?
Thx Berg

Are you running

    ruby -pi -e ...

? If yes, can you paste the entire command verbatim and say what'd you like
it todo? Unix shell or Wndows? (important for quoting rules and newline
conventions.)
