I went through the rsyslog.d/50-default.conf file.. the entries in the files are like this.
auth,authpriv.* /var/log/auth.log
*.*;auth,authpriv.none -/var/log/syslog
#cron.* /var/log/cron.log
#daemon.* -/var/log/daemon.log
kern.* -/var/log/kern.log
#lpr.* -/var/log/lpr.log
mail.* -/var/log/mail.log
#user.* -/var/log/user.log
In some entries the log directory path is prefixed with hyphen sign(-). can anyone please tell me what does it means..
