Here is a pointer: Instead of printing the data, store it in a data structure that is declared outside the outer foreach loop. Then when you are done with all input files, write the output into a single file. If you haven't yet worked with nested data structures in Perl, I can recommend perlreftut, perldsc and perllol (the latter for arrays of arays).
