cat


cat: [from `catenate' via UNIX `cat(1)'] vt.
   1. [techspeak] To spew an entire file to the screen or some other
   output sink without pause.  2. By extension, to dump large amounts
   of data at an unprepared target or with no intention of browsing it
   carefully.  Usage: considered silly.  Rare outside UNIX sites.  See
   also dd, BLT.

Among UNIX fans, `cat(1)' 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, 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(1)' 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 two files. The name `cat' for the former operation is just as unintuitive as, say, LISP's cdr.

Of such oppositions are holy wars made....
