Hi, did you read through all of perlintro as you were advised earlier?

Here's how to read a file and print it line by line, as explained in more detail in perlop - IO Operators: 

use strict; use warnings;

my $file_in = "C:/Users/Joe/Documents/Genealogy/birdt.ged";

open my $FILE, "<", $file_in or die "could not open $file_in $!";

while ( my $line = <$FILE> ) {
    print "$. $line";
} 

close $FILE or die "could not close $file_in $!";

__END__

Although I would rather use the convenience of a filehandling module like Path::Tiny : 

use strict; use warnings;
use Path::Tiny; # imports path()

my $file_in = "C:/Users/Joe/Documents/Genealogy/birdt.ged";

my $line_num = 0;
for my $line ( path( $file_in )->lines ) {
    print sprintf '%4d %s', ++$line_num, $line;
} 

__END__

Hope this helps!


The way forward always starts with a minimal test.
