Hello all,

I have been looking at this for a few days and cannot see an answer so I humbly ask your opinion.

I have a data file that is laid out like the following:

DOE JOHN
123
DENIRO ROBERT
123
123
123
CUBE ICE
123
123

[download]

There are names followed by lines that have numbers in them that correspond to each name. The name line can be followed by any number of number lines. I want to extract the name and its corersponding number lines if the name matches and/or the number lines match some user input.

The following code is where I am starting:

use strict;
use warnings;


open OUTPUT, "> info.txt" or die $!;
print "What file do you want parsed? ";

my $file1 = <STDIN>;

print "Name: ";

chomp (my $name = <STDIN>);

open FILE, "$file1";

while (<FILE>) {
    
    if (/$name/.../\n/) {
        
        print OUTPUT $_ until ($_ ne\d+/); 
            
            }
            
        }

I would be most grateful for any guidance. Thanks!
