From 0ae29bfc8b5567361a2c6468b45a1e00a7c7ecaf Mon Sep 17 00:00:00 2001 From: Andrej Manduch Date: Tue, 25 Nov 2014 20:47:49 +0100 Subject: [PATCH] journalctl: print all possible lines immediately with --follow + --since When I tryed to run journalctl with --follow and --since arguments it behaved very strangely. First It prints logs from what I specified in --since argument, then printed 10 lines (as is default in --follow) and when app put something new in to log journalctl printed everithing from the last printed line. How to reproduce: 1. run: journalctl -m --since 14:00 --follow Then you'll see 10 lines of logs since 14:00. After that wait until some app add something in the journal or just run `systemd-cat echo test` 2. After that journalctl will print every single line since 14:00 and will follow as expected. As long as --since and --follow will eventually print all relevant lines, I seen no reason why not to print them right away and not after first new message in journal.
