Re^3: Problem with String replace in file

[meraxes]

I suspect your problem is that you are writing back to the filehandle IN when you (presumably) only opened it for read.

open( IN, '<', $filename ); # input
open( OUT, '>', 'newfilename.txt' ); # output
while ( <IN> ) {
    s/\|\|/|\\N|/g;
    print OUT;
}
close IN;
close OUT;

This was correct, thank you. || is replaced by |\N| throughtout newfilename.txt.
