Pádraig, thanks for your response. In my reproducer environment, it doesn't totally update. RHEL7 Samba server, RHEL6 Samba client.
Unless I provided the extra interval parameter. When I run it in Redhat9, I don't need any extra, it refresh automatically.

Could you clarify whether the rhel7 version of tail is too slow when showing updates to the file, or misses updates to the file entirely. There have been various fixes to tail, so it would be worth verifying how the latest behaves, like: wget https://ftpmirror.gnu.org/coreutils/coreutils-8.29.tar.xz tar -xf coreutils-8.29.tar.xz cd coreutils-8.29 ./configure --quiet && make -j$(nproc) src/tail -f /media/samba/test.file cheers, Pádraig This message and the information contained herein is proprietary and confidential and subject to the Amdocs policy statement, you may review at https://www.amdocs.com/about/email-disclaimer <https://www.amdocs.com/about/email-disclaimer>
