How about doing it in Perl?
use strict; # keeping
use warnings; # myself
use Perl::Critic; # honest ;)
use Carp; # croak
my $filename = "/some/random/file.txt";
my $text;
{
local $/; # undef the input file sep, so we don't break on \n
open(my $fh, $filename) or croak qq("I can't even open a file, sigh");
$text = <$fh>; # slurp
}
$text =~ s#\n#\*#gmsx; # replace \n's with *'s. Customise to your
heart's content :)
print $text;
Hope this helps,
Michael...
