[TUHS] fmt(1): history, POSIX, -t, -c

Fri May 29 02:08:22 AEST 2020

It's nice to see a uuencode email attachment once again!

Clem (who, by the way, is correct about the origin of fmt, it was part 
of Kurt Shoens' Mail program at Berkeley) has perfect timing. This 
coming Monday, 6/1/2020, is the 40th anniversary of the uuencode email 
attachment. (The date is based on the date in the uuencode man page in 
the 2.8BSD and 4.2BSD archives at 
https://www.tuhs.org/Archive/Distributions/UCB/ )

There has been some amusing coverage of the "25th anniversary of the 
email attachment", commemorating Nat Borenstien's creation of MIME in 1992.

Any thoughts on a proper commemoration of the 40th anniversary?
