I re-tested this in Emacs 29 with the current Macos, and the bug is
still present there.

I can't reproduce this on GNU/Linux, but I can reproduce it on macOS
using Emacs 27.

The recipe can in my case be simplified to:

0. emacs -Q
1. M-x eshell
2. echo foo | grep foo

Results: I see the line "foo" printed, then it stalls until I kill it
with C-c.

I never see the beep the OP talks about, but I see the same stalling
as above when I say 'ps -ef | grep "test"'.

Perhaps this is caused by some difference between BSD grep and GNU
grep.

Best regards,
Stefan Kangas

Thank you a lot for your prompt response!  Since I am on GNU/Linux, and
after your reply I am pretty confident that this is Mac OS-specific,
I will have to leave it to others for further investigation.  Also, you
might want to evaluate this form: (info "(emacs)Checklist") and make
sure to follow the instructions there (in particular, check whether the
problem appears with emacs -Q).

> Thanks

Thank you for cooperation, and I hope this issue will be resolved!

Hello,

I would be thankful if you could check whether the problem persists in
latest Emacs.  If yes, please lay out the steps to reproduce your
problem.  I tried

  ps -ef | grep "test"

in Eshell and it seemed to work fine on the development version of
Emacs; it is possible that the problem disappeared and the bug can be
closed.

Best regards,
Marcin Borkowski
