1A Brief history of sudo(8): 2 3Sudo was first conceived and implemented by Bob Coggeshall and Cliff 4Spencer around 1980 at the Department of Computer Science at 5SUNY/Buffalo. It ran on a VAX-11/750 running 4.1BSD. An updated 6version, credited to Phil Betchel, Cliff Spencer, Gretchen Phillips, 7John LoVerso and Don Gworek, was posted to the net.sources newsgroup 8in December of 1985. 9 10In the Summer of 1986, Garth Snyder released and enhanced version 11of sudo. For the next 5 years, sudo was fed and watered by a handful 12of folks at CU-Boulder, including Bob Coggeshall, Bob Manchek, and 13Trent Hein. 14 15In 1991, Dave Hieb and Jeff Nieusma wrote a new version of sudo 16with an enhanced sudoers format under contract to a consulting firm 17called "The Root Group". This version was later released under the 18GNU public license. 19 20In 1994, after maintaining sudo informally within CU-Boulder for 21some time, Todd Miller made a public release of "CU sudo" (version 221.3) with bug fixes and support for more operating systems. The 23"CU" was added to differentiate it from the "official" version from 24"The Root Group". 25 26In 1996, Todd, who had been maintaining sudo for several years in 27his spare time, brought sudo development under the umbrella of his 28consulting firm, Courtesan Consulting. Courtesan remains committed 29to a free sudo and is sponsoring another sudo rewrite as well as 30continued development of the sudo 1.x code base. 31 32In 1999, the "CU" prefix was dropped from the name since there has 33been no formal release of sudo from "The Root Group" since 1991 34(the original authors now work elsewhere). As of version 1.6, Sudo 35no longer contains any of the original "Root Group" code and is 36available with a BSD-style license. 37 38In 2004, Todd incorporated as GratiSoft, Inc. to provide commercial 39support and enhancements to the sudo community. 40 41sudo, in its current form, is maintained by: 42 43 Todd Miller <Todd.Miller@courtesan.com> 44 45Todd continues to enhance sudo and fix bugs. 46
