Subject: substituted command won't inherit stdin in pipeline
Date: Wed, 13 Nov 2019 12:52:20 +0300	[thread overview]
Message-ID: <CAH7i3Lo57yAd==m7zF+8mtETqYDDSptmdzxF-2t_pu42fe9ztQ@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 453 bytes --]

On all sh implementations I have, this command

    echo foo | echo "$(cat)"

prints 'foo', except for zsh, it hangs instead. From that I gather cat
doesn't inherit echo's stdin, and it waits for input.

This works though

    echo foo | { echo "$(cat)"; }

and it doesn't make any sense, both should work as per the standard if I'm
not mistaken.

Is this a bug, or documented behavior?
