Package: logcheck Version: 1.4.5 Severity: normal Dear Maintainer,
after upgrading to Bookworm (Debian 12) on every run of logcheck (from crontab) I receive an additional e-mail from cron where grep complains about RegEx starting with "?". Subject: Cron <logcheck@dom3> if [ ! -d /run/systemd/system ] && [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck; fi Body of the e-mail: grep: warning: ? at start of expression grep: warning: ? at start of expression grep: warning: ? at start of expression grep: warning: ? at start of expression grep: warning: ? at start of expression grep: warning: ? at start of expression grep: warning: ? at start of expression grep: warning: ? at start of expression This happens with the logcheck package from Trixie (Debian 13), too. The behaviour is apparently related to the fact that grep now (i.e. since Bookworm) reacts more sensitively to the situation described (“? ” at the beginning of the RegEx), as stated in the release notes and announced by apt-listchanges. But why does this happen with logcheck? I can't find any RegEx that starts with a question mark: # grep -r ^? /etc/logcheck/ # Any ideas?
