Package: less Version: 487-0.1+b1 Severity: important Tags: upstream This is not a bug in any current Debian package, but an FYI about an upstream regression.
As of version 520 the following test-case will wait a full 5 seconds before printing "hello": (echo "hello"; sleep 5; echo "bye bye") | less -F Before that it would print "hello" immediately, and then "bye bye" 5 seconds later. See this report & discussion on the git mailing list: https://public-inbox.org/git/87k1orqpxj....@evledraar.gmail.com/ Linus posted a patch that works for me to solve this, but the upstream maintainer hasn't commented: https://public-inbox.org/git/ca+55afxjusvhhwqgthgilr537bghkd-lecxvv8kzbtmmco1...@mail.gmail.com/
