CAT
     
        Common Abstract Tree Language.  R. Voeller & Uwe Schmidt, U
        Kiel, Germany 1983.  Universal intermediate language, used by
        Norsk Data in their family of compilers.  "A Multi-Language
        Compiler System with Automatically Generated Codegenerators,
        U. Schmidt et al, SIGPLAN Notices 19(6):202-2121 (June 1984).
     
        [{Jargon File}]

cat
     
         (From "catenate") {Unix}'s command which copies one or
        more entire files to the screen or some other output sink
        without pause.
     
        See also {dd}, {BLT}.
     
        Among {Unix} fans, cat is considered an excellent example of
        user-interface design, because it delivers the file contents
        without such verbosity as spacing or headers between the files
        (the {pr} command can be used to do this), and because it does
        not require the files to consist of lines of text, but works
        with any sort of data.
     
        Among Unix haters, cat is considered the {canonical} example
        of *bad* user-interface design, because of its woefully
        unobvious name.  It is far more often used to {blast} a file
        to standard output than to concatenate files.  The name "cat"
        for the former operation is just as unintuitive as, say,
        LISP's {cdr}.
     
        Of such oppositions are {holy wars} made.
