It might be worth pointing out (in case you see examples elsewhere) that on
UNIX/etc. the '*.txt' is expanded by the command interpreter (or "shell")
BEFORE it is passed to the perl script. On such platforms you do not need
the glob (same applies for cygwin if you are using win32 bash as a shell).
Of course to make the code cross platform you should always use glob.
