Package: less Version: 551-1 Severity: normal Run the following command:
( trap '' INT; while true; do echo foo; done; ) | less -M Then type one or a few [PageDown], and type [End] to go to the end, but since this is an infinite loop here[*], this will hang. Type Ctrl-C to abort. One is back to the beginning of the file, at line 1 (less shows something like "lines 1-59") instead of remaining at the same position (or going to some higher position). In case of interrupted [End], less should never go backward. I can also reproduce this bug with less 481 (Debian/stretch) and 487. [*] In practice, this can just be a command with a lot of output, but which hasn't finished yet. -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.2.0-2-amd64 (SMP w/8 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=POSIX (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages less depends on: ii libc6 2.29-1 ii libtinfo6 6.1+20190803-1 less recommends no packages. less suggests no packages. -- no debconf information -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
