Heh! I recognise some of that code :) _And_ you're planning to use one of my modules to do the array comparison.

In general, if you have a list of filenames and want to get a list of file contents then you'd better be sure that the files are small or you've got a lot of memory! That being said, you can do it like this:

my @files = qw(file1 file2 file3);
my @contents;

foreach (@files} {
  open FILE, $_ 
    or do { warn "Can't open $_: $!\n"; next }

  local $/;
  push @contents, <FILE>;
}

This gives you each file's contents in a scalar. To get an array of each file's contents you'd do this:

my @files = qw(file1 file2 file3);
my @contents;

foreach (@files} {
  open FILE, $_ 
    or do { warn "Can't open $_: $!\n"; next }

  push @contents, [<FILE>];
}
