The POSIX specification requires that the prompt be issued to stderr:-
Fair enough. Thanks for the info.
What my patch essentially did was:
if (isatty(stderr)) { /* interactive */
human=open("/dev/tty");
fcntl(human,F_SETFD,FD_CLOEXEC);
} else {
human=stderr;
}
/* subsequent prompts written to human rather than stderr */
Note bash does special interactive handling anyway.
For example $PS1 is only set for interactive shells.
