You could probably have found "What does UUOC mean?" in your favorite search engine, even if you didn't add "cat" as an extra hint. The Useless Use Of Cat Award is given whenever somebody uses the cat utility in a useless way, the classic example being as a replacement for I/O redirection in the Unix shell: $ cat some_file | my_program instead of the simpler: $ my_program <some_file There are many useful ways to use cat, of course; but it's hardly ever useful (nor portable) to call it from Perl programs, because the few useful tricks it performs are *quite* simple, such as adding line numbers. Conventional wisdom tells us rightly that simple tasks are better accomplished with a little bit of Perl code than by starting up another process; and cat is hardly used for anything but simple, simple tasks.
