:UN*X: n. Used to refer to the UNIX operating system (a trademark of
AT&T) in writing, but avoiding the need for the ugly
{(TM)} typography.
Also used to refer to any or all varieties of Unixoid operating
systems. Ironically, lawyers now say that the requirement for the
TM-postfix has no legal force, but the asterisk usage is
entrenched anyhow. It has been suggested that there may be a
psychological connection to practice in certain religions
(especially Judaism) in which the name of the deity is never
written out in full, e.g., `YHWH' or `G--d' is used. See also
{glob}.
