Package: logcheck

Severity: normal

Dear Maintainer,

after was solved this one

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019335

I have an email like this every cron

From: Cron Daemon <ro...@G5045.stecalle.uff>
To: ro...@G5045.stecalle.uff
Subject: Cron <logcheck@G5045> if [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck; fi

grep: warning: stray \ before !
grep: warning: stray \ before "
grep: warning: stray \ before "
grep: warning: stray \ before &
grep: warning: stray \ before "
grep: warning: stray \ before "
grep: warning: stray \ before "

and many more lines.

However logcheck seems work well (I have the email of the logs too).

Thanks

Stefano

Think this is an issue in the rules shipped by debian - there have
been some unwanted backslashes in some rules files for ages, and
apparently grep has started warning about these. The rules should
only quote things that are special for regular expressions, so +, ., *
( etc, but not other characters

The patch in https://salsa.debian.org/debian/logcheck/-/merge_requests/14
should fix these - please review!

Dear Maintainer,

same here, I've patched it locally and just wanted to supply the patch.

Hmm, I've just noticed, there actually already seems to be one. I send
this nonetheless.

Hi Thomas - i provided the previous patch: you found a couple more
instances that i missed (the \/ in ignore.s.server/samba and
ignore.d.workstation/kernel):
I've updated https://salsa.debian.org/debian/logcheck/-/merge_requests/14
to include your work as well -

Jose, as the debian maintainer are you able to review and push a fix
into the repository? (you could also credit Thomas in the changelog,
which isnt updated in the merge request. The merge request applies to
1.3.24 as i wasnt sure if the other commits in the master branch (ie
adding an empty package) were ready for release - but can rebase if
you want?)

This bug is going to be really annoying, so it would be awesome if it
could be fixed

Cheers!
