On Unix, cygwin, etc:

   cat dir/*.txt > output.txt

Or if you need "deep" copy:

   cat $(find dir -name '*.txt') > output.txt

You could write a portable solution in Python (as in Martin Laloux's 
post), but most modern command-line environments have similar (but not 
identical) support for globbing and redirecting files.  If you're 
getting the glob pattern from a user, they may expect subtly 
platform-dependent behaviors, in which case portability might not as 
important as native feel.
