PIP

PIP /pip/ vt.,obs.  [Peripheral Interchange Program] To
   copy; from the program PIP on CP/M, RSX-11, RSTS/E, TOPS-10, and
   OS/8 (derived from a utility on the PDP-6) that was used for file
   copying (and in OS/8 and RT-11 for just about every other file
   operation you might want to do).  It is said that when the program
   was originated, during the development of the PDP-6 in 1963, it was
   called ATLATL (`Anything, Lord, to Anything, Lord'; this played on
   the Nahuatl word `atlatl' for a spear-thrower, with connotations
   of utility and primitivity that were no doubt quite intentional).
