Subject: Bug: reading from tty inside process substitution
Date: Sun, 12 Nov 2023 10:59:33 -0500 [thread overview]
Message-ID: <CAA=-s3xCf4wx826U8jEjO_j5-1kcTi8v2=VZPiabKMo-meKq0Q@mail.gmail.com> (raw)

The below code hangs after reading the line from the terminal:
read foo < <(read bar </dev/tty; echo $bar)
The actual use case I ran into this involved a select, which also hangs
after item selection:
read foo < <(select item in a b c; do break; done </dev/tty >/dev/tty
2>&1; echo $item)
Both commands work as intended in both bash and ksh.
If I replace the outer `read` with a command substitution, it works in zsh
as well (it started out as `read` because I was getting multiple values out
of the `select`ed line).
I'm running zsh 5.9, tested on macOS 13.6 and 14.0 and Ubuntu 22.04.3
