Hi Yazu,

Really Excellent logic when I have seen your code. Thank you very much for your time and for your thoughts.

I have modified the logic accordingly and below is the code:

Code:
#!/usr/bin/perl

$file='feedfile';
open(FILE,$file)|| die ("could not open file $file: $!");


my $goodfile = "goodfile";
my $badfile = "badfile";
my $footer_len = 4;
my $datarec_line = 1;

my (@whole, @header, @footer, @goodlines, @badlines, @fields);
my $line;
$line = $_;

@whole = <FILE>;

do {
  $line = shift @whole;
  push @header, $line;
} while $line !~ /^# PRODUCT/;

@footer = splice @whole, -$footer_len;


foreach (@whole) {
$line = $_;
@fields = split (/\|/, $line);

if( $fields[57] eq " ")
{
 push @badlines, $line;
}

elsif( $fields[32] eq "N.A."  && $fields[33] eq "N.A." && $fields[34] eq "N.A." && $fields[38] eq "N.A." && ($fields[62] eq "N.A." ||  $fields[62] eq " "))
{
push @badlines, $line;
}

else
{
push @goodlines, $line;
}

}

$footer[$datarec_line] =~ s/\d+/scalar @goodlines/e;

open my $fh, ">", $goodfile;
print $fh @header, @goodlines, @footer;
close $fh;

open my $fh1, ">", $badfile;
print $fh1 @badlines;
close $fh1

After running the code I have found that there are 4 lines in between the data records that are differentiate the data.
i.e.
Code:
grep -n "#  PRODUCT"  feedfile
1206675:# PRODUCT=Convertible 
1261566:# PRODUCT=Nationals
1270395:# PRODUCT= Agencies
1274335:# PRODUCT=Regionals

As above we can see that these 4 lines are invalid records.

Now, while calculating the Rowcount we need to ignore these 4 records. i.e.
Code:
$footer[$datarec_line] =~ s/\d+/scalar @goodlines/e;



Here while calculating the rowcount and substituting the new count, we have to ignore the above 4 lines(records).

May be reducing the array by 4. not sure though.

How can we reduce the row count by 4 so that we can get the actual count.

Really appreciate your time and thoughts.

Finally,

I did the following :

Code:
$footer[$datarec_line] =~ s/\d+/(scalar @goodlines - 4)/e;

Thanks a lot Yazu. I am really Very much thankful to you.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
