Ok, I tried this script and got the following error. "You said to perform 0 tests at Counter.pl line 13". What should I change? Sorry like I said I am new at writing perl scripts. My script might not make sense.lol

    This:

    chomp(my @HANT = <$handle>);
...
plan tests => scalar @hant;

    Perl is case sensitive, unless otherwise stated for details. @HANT and @hant are different arrays.

      Ok this works now and correctly returns count. The only problem is that it returns errors and extra junk as well. How do I get rid of it? Why does it show expected values? 
      nic@nic-VirtualBox:~/Desktop/5-27-17$ perl Counter.pl
1..612
ok 1 - Number of matches found for Laesu1
ok 2 - Number of matches found for Patat1
not ok 3 - Number of matches found for Hydru2
#   Failed test 'Number of matches found for Hydru2'
#   at Counter.pl line 18.
#          got: '1'
#     expected: '2'
not ok 4 - Number of matches found for Armost1
#   Failed test 'Number of matches found for Armost1'
#   at Counter.pl line 18.

      I just want this for example. 
      Number of matches found for Pacta12: 1 

Number of matches found for Armost1: 0

        Adjust the @counts array to reflect the actually expected matches. From the output the test script delivers, you can tell ("got: ") it should be: 

        my @counts = (0, 1, 1, 0, 1, ...); # ... is a placeholder for any othe
+r values
