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!

Bug#1020827: grep: warning: stray \ befor ...

[Stefano Callegari]

Package: logcheck
Version: 1.3.24
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 
To: r...@g5045.stecalle.uff
Subject: Cron 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
