Thank you and Karel too. I'm lucky as the patch applies cleanly on Ubuntu's version which is where the bug was first noticed [*]. > Please feel free to notify upstream directly in the future if you find > any similar issues. Will do. > PS. Please note that tailf is deprecated. Use tail -f Good to know. FTR, "tail -f" is what I noticed the problem with but I switched to tailf because it was from the same source tree so easier to bisect.

Package: util-linux Version: 2.27.1-6 Hello, I noticed a regression after upgrading from 2.26.2 to 2.27.1. Here are the steps to reproduce: 1) Start script session (same issue when script is saving to /dev/null) script # or: script /dev/null 2) Tail a file tailf /var/log/syslog 3) Press "Enter" 2 times 4) Notice the script process taking 100% CPU This regression was introduced upstream by this commit: https://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/?id=54c6611d6f7b73609a5331f4d0bcf63c4af6429e Thanks, Simon
