in thread Problem with String replace in file

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;
