Telling us that filenames are something like x-y where x and y are strings of digits isn't enough for us to figure out how to determine which file is file1, file2, ...

Give us details.
  1. How do you know which files are to be combined and in what order?
  2. Are the names of the files just two strings of digits separated by a single minus sign, or are the other characters in the name that need to be skipped over (or used to determine the order in which they're to be concatenated?
  3. How do you determine the output file name (or do you just want the output to be written to stout?
  4. Can we choose which shell we want to use, or have you decided the only one shell should be used? If only one, which one?
