Greetings,

I have two arrays, one is the slurped contents of multiple files and the other is a list of strings. The goal is to check the file array to see if any of the elements of the other array exist.

Right now I am doing this in a very clumsy way:

@files = <FILE>;
chomp(@files);
@strings = qw(ABC DEF GHI JKL);

foreach $file (@files) {
  my $data = slurp $file;
    foreach $string(@strings) {
      if (index(lc($data),lc($string)) ge 0) {
        print " Match\n";
      }
}

I am using nested foreach loops to run the search on $data for each element in @strings. I am sure this is very clumsy.

What I want is to put compare @strings against @data once and if there is a match on any element of @strings inside of @data then perform the print of "Match".

Thanks
