System name: biohazard-cafe.mit.edu
Type and version: Sun-Fire-280R 9.0.23 (with mkserv)
Display type: unknown
Shell: /bin/sh
Window manager: unknown
What were you trying to do?
I took over a keyboard for a friend, and was editing one
of his files with vi.
I attempted to pipe a paragraph of text through fmt.
What's wrong:
The shell added five lines of garbage output to the results of
the shell escape:
stty: : No such device or address
Running standard startup activities ...
zwgc: Unable to open X display -- disabling X driver.
zwgc: To receive Zephyrgrams, (type `zwgc -ttymode').
mesg: cannot stat
(The rest of the text after this was the output of fmt.)
What should have happened:
Non-interactive shells shouldn't print text in a way that
messes up vi like this. A stock Unix system would check
to see if csh set $prompt; Athena might have other
variables that also control verbosity.
Please describe any relevant documentation references:
I fully expect my friend to have standard dotfiles, but I
haven't scrutinized them, or tried to reproduce this with
a test account. "where vi" reports "/usr/bin/vi" and
"/usr/ucb/vi", and the error was observed on biohazard-cafe.
