i am reading all the files and will store it in an array called @filelist

@filelist
---------
file 01
file 02
file 03
file 04
file 05
file 06

i am reading each element from the file - 1 and will see if it exists in any of the files avialable in @filelist if exists i need to print the value of that element to text file

for example when i read a file - 1 , the first element is K, take the K and seacrh if it exists in any of the files available in @filelist, for example the value of K is available in file 01, print the K 01 JK 1234 to some text file called output.txt

My code

my @array;

open F, "$input_file" or die "Couldn't Open File: $!";
while (<F>) {
chomp;
( my ( $name, $num ) = split /    /, $_ ) ;
push (@array, $name);
}
    
foreach my $name (@array) {

}
