Definitions of 'vi'
The New Hacker's Dictionary
1. vi [from ‘Visual Interface’] A screeneditor crufted
together by Bill Joy for an early BSD release.
Became the de factostandardUnixeditor and
a nearly undisputed hackerfavoriteoutside of MIT until the rise of
EMACS after about 1984. Tends to frustrate new
users no end, as it will neither take commands while expecting input text
nor vice versa, and the defaultsetup on older versions provides no
indication of which mode the editor is in (years ago, a correspondent
reported that he has often heard the editor's name pronounced /vi:l/; there is now a vi clone named
vile). Nevertheless vi (and variants
such as vim and elvis) is still widely used (about half the respondents in
a 1991 Usenet poll preferred it), and even EMACS fans often resort to it as
a maileditor and for smallediting jobs (mainly because it starts up
faster than the bulkier versions of EMACS). See holy
wars.
