I already have parsed a file and delimited it with PIPE (|) --- except after the last field.
Is there a way I can add the PIPE  (|) delimeter at the end of the line without doing the whole thing again? I need some sort of global pattern search and add or update feature.

you can use the \n char as your reference, since \n indicates end of line. Basically search for \n and replace it with a | and \n

Eg.
lets say each line of your file is stored in a var called $var.
$var is in a loop.

open(FILE,"the_piped_file") || die $!;
while $var(<FILE>){
$var=~ s/\n/\|\n/;
}
close(FILE);

maneshr,

thank you ... works great as long as the last column in the data is not blank ... for those lines that have a blank space, it is not placing the |.
Any ideas why?

{local $^I=''; local @ARGV=('the_piped_file');
  while( <> ){ s/$/|/; print }
}
