Hello Monks, I am a complete perl newbie: I have inherited some ksh script with embedded perl and would like some syntax help. here is what I have recieved and added: 
if [ "X${substitute}" = "Xy" -o "X${substitute}" = "XY" ]
then
    cat $inputfile |  perl -e 'while(<STDIN>)
    {
            if( length( $_ ) > 3 )
            {
                 @args=split(/\|/,$_);
        if( $args[1] eq '$service' && $args[3] eq '$bundle' )
        {
                    @args=split(/\|/,$_);
                    $args[4] =~ s/N/Y/;
                    print join("|",@args);
        }
                else
        {
                    print $_
        }
            }
            else
            {
            print $_
            }
    }' > $tmpfile

The gist of the code is to modify a line in a file by counting out args seperated by a |.

TIA,
