console jockey

from The Free On-line Dictionary of Computing (8 July 2008)

terminal junkie
console jockey

   (UK) A {wannabee} or early {larval stage} hacker who spends
   most of his or her time wandering the directory tree and
   writing {noddy} programs just to get a fix of computer time.
   Variants include "terminal jockey", "console junkie", and
   {console jockey}.  The term "console jockey" seems to imply
   more expertise than the other three (possibly because of the
   exalted status of the {console} relative to an ordinary
   terminal).

   See also {twink}, {read-only user}.
