Though I'm sure you meant this casually, and yes, vim has been around quite a while, vim is not vi. https://en.wikipedia.org/wiki/Vim_(text_editor) https://en.wikipedia.org/wiki/Vim_(text_editor) " Vim (/vɪm/;[3] a contraction of Vi IMproved) is a clone of Bill Joy's vi text editor program for Unix. It was written by Bram Moolenaar based on source for a port of the Stevie editor to the Amiga[4] and first released publicly in 1991. " https://en.wikipedia.org/wiki/Vi https://en.wikipedia.org/wiki/Vi " The original code for vi was written by Bill Joy in 1976, as the visual mode for a line editor called ex that Joy had written with Chuck Haley.[2][3] Bill Joy's ex 1.1 was released as part of the first BSD Unix release in March, 1978. It was not until version 2.0 of ex, released as part of Second Berkeley Software Distribution[4] in May, 1979 that the editor was installed under the name "vi" (which took users straight into ex's visual mode), and the name by which it is known today. " " In 1989 Lynne Jolitz and William Jolitz began porting BSD Unix to run on 386 class processors, but to create a free distribution they needed to avoid any AT&T-contaminated code, including Joy's vi. To fill the void left by removing vi, their 1992 386BSD distribution adopted Elvis as its vi replacement. 386BSD's descendants, FreeBSD and NetBSD followed suit. But at UC Berkeley, Keith Bostic wanted a "bug for bug compatible" replacement for Joy's vi for BSD 4.4 Lite. Using Kirkendall's Elvis (version 1.8) as a starting point, Bostic created nvi, releasing it in Spring of 1994.[28] When FreeBSD and NetBSD resynchronized the 4.4-Lite2 codebase, they too switched over to Bostic's nvi, which they continue to use today.[28] "
