The Jargon File (version 4.4.7, 29 Dec 2003):

terminal junkie
 n.

    [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. Appropriately, this term was used in the works of William
    S. Burroughs to describe a heroin addict with an unlimited supply.
