What were you trying to do that didn't work?

While piping or redirecting information through 'more' and pressing CTRL-C the INT signal is not getting received by 'more', the signal gets to the complete process group except more. This seems to be a change in behavior from RHEL 7 and RHEL 8.
The same happens on Fedora. It does not happens with 'less'.

Please provide the package NVR for which bug is seen:

util-linux-core-2.37.4-15.el9

util-linux-core-2.38.1-4.fc38

How reproducible:

Always

Steps to reproduce

1. With any text file that has enough data to be paginated run:
2. grep . /var/log/messages | more
   or
3. more < /var/log/messages
4. On first page press CTRL-C

Expected results

1. All group processes (if any) including 'more' gets interrupted.

Actual results

1. Press 'q' to exit as nothing happens on more (actually grep or any other process in the process group gets the signal and behaves accordingly)
