In running bup regression tests, it basically does
script -q -c "/path/to/bup/under/test some bup args" /dev/null to ensure that the program is tested with a tty as input, separately from just running it. I have been running the test suite "< /dev/null > CHECK.foo 2&1" more or less. This results in the top-level script exiting because no characters are available on stdin, even though the program is still running. So: Does script(1) (not specified by POSIX) require that stdin is a tty? Does it say that if there is EOF on stdin, then script should exit, whether or not the program being run has exited? Is this just a bug, that EOF on script stdin should lead to perceived EOF on the program being run's (pty) stdin? And that script should only exit when the program exits?
