With DISPLAY set, running “TERM=dumb vi | cat” with an appropriate symlink in $PATH: vim Prints “Vim: Warning: Output is not to a terminal” to stderr, waits about a second, then runs without clearing the screen, using ANSI escapes to move around. elvis 1.4 Prints “This termcap entry lacks the :up=: capability” to stderr, fails with status 1. elvis 2 (more precisely, the elvisnox script from Debian) Prints “termcap needs up” to stderr, fails with status 1. nvi Prints “ex/vi: Vi's standard input and output must be a terminal” to stderr, fails with status 1. With TERM=dumb but standard output going straight to the terminal, the situation is not very different for vim and elvis, while nvi gets utterly confused (it only writes output to the bottom line for some reason). So I think it still makes sense to work around this bug in the vi clones.
