Yes exactly. The header is the 2 first lines of each file.

I want a script that takes all lines following the header, from all .ktf files in the current directory, and merges them into one file, ultimately with the header added to it.

I'm sorry, I don't understand the $fh_in and $fh_out variables. This is my first perl script >_<

If someone could give me a more detailed reply on how to read and merge all lines following the 2 first lines, in all .ktf files in a directory, and write it to a file, I would be eternally grateful! :)
