This manual page documents the cron-silencer command.
cron-silencer is a program to easily filter messages from cron jobs. cron-silencer uses regular expressions to check if a given output line is pointless or maybe not.
The initial idea behind cron-silencer was to have more control over stupid cron job messages and keep your mailbox clean. Just pipe the output through cron-silencer to shut them up. cron-silencer filters out well-known lines and only if there are unknown ones (presumably errors) you get the full message with the incriminated line marked.
Filters out well-known lines from Cronjobs. If there are no others, you will not be bothered.
If one line does not fit you get the whole message, so you get the whole context.
The first supicious line gets marked.
Presets exist for mysql-zrm,rsnapshot, rsync, spamassassin, webalizer, sophos, ntpdate and bacula.
-fFilter to use. Choose one of: mysql-zrm, rsync-rsnapshot, spamassassin, webalizer, sophos, ntpdate and bacula.
-FFile with filter lines to use. Needs a path name as parameter.
-a File with additional filter lines to use. Needs a path name as parameter.
Has to be combined with -F or -f.
May be given multiple times.
For identical patterns, rules superseed in order of appearance.
-hPrint out help.
/some perl compatible regex/ => number or 'u' for unlimited occurance
# comment
