Here is an example using pattern matching, if your looking to see if the word is contained within any elements of the array

use v5.14;
chomp(my $word = <STDIN>); #get word from command line
                          #chomp removes newline for search
foreach my $name(@array){ #loop through names
   if($name =~ m/$word/i){ #if the word is contained within
      say $name;  # print out the name with a newline (say)
   }
}

otherwise, if your looking for exact maches just do something like this.

use v5.14;
chomp(my $word = <STDIN>); 
                          
foreach my $name(@array){ 
   if($name eq $word){ #if the name equals the word
      say $name;
   }
}
