I have a bar delimited file of some 1500 lines. As I am processing
each line in the file I need to replace empty entries eg ||
with |\N| ( the null value in postgres) I use the following regexp 
$line =~ s:\|\|:\|\\N\|:g

This works for the first 40-50 lines and then seem to give up
leaving occurrences of the || string in the resulting file
My test case code is the following 
#!/usr/bin/perl -w

use strict;
 
open INPUT, 'try.asc';
 
while(my $line=<INPUT>)
{
print qq(Original line = $line);
$line =~ s/\|\|/\|\\N\|/g;
print qq(New line = $line);
}

Has any one any ideas?
