File::Slurp is your friend here. it can't be easier than this:
use File::Slurp ;
write_file( 'filename', "header text\n" ) ;
that will work even on a 0 length file if it is writeable. touch should
leave the files writeable. but with that call, you don't even need to
have a file there in advance.
and this will add more text to the end of the file:
append_file( 'filename', "more text\nand even more\n" ) ;
