  1. Foobar

    The terms foobar /ˈfuːbɑːr/, fubar, or foo, bar, baz and qux are sometimes used as placeholder names in computer programming or computer-related documentation. They have been used to name entities such as variables, functions, and commands whose purpose is unimportant and serve only to demonstrate a concept. The words themselves have no meaning in this usage. Foobar is sometimes used alone; foo, bar, and baz are sometimes used in that order, when multiple entities are needed. The usage in computer programming examples and pseudocode varies; in certain circles, it is used extensively, but many prefer descriptive names, while others prefer to use single letters. Eric S. Raymond has called it an "important hackerism" alongside kludge and cruft.

The New Hacker's Dictionary

  1. foobar

    [very common] Another widely used metasyntactic variable; see foo for etymology. Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972. Hackers do not generally use this to mean FUBAR in either the slang or jargon sense. See also Fred Foobar. In RFC1639, “FOOBAR” was made an abbreviation for “FTP Operation Over Big Address Records”, but this was an obvious backronym. It has been plausibly suggested that “foobar” spread among early computer engineers partly because of FUBAR and partly because “foo bar” parses in electronics techspeak as an inverted foo signal; if a digital signal is active low (so a negative or zero-voltage condition represents a "1") then a horizontal bar is commonly placed over the signal label.
