The facility is one of the following keywords: auth, authpriv, cron,
daemon, kern, lpr, mail, mark, news, security (same as auth), syslog,
user, uucp and local0 through local7.
The priority is one of the following keywords, in ascending order:
debug,info, notice, warning, warn (same as warning), err, error (same
as err) crit, alert, emerg, panic (same as emerg). The keywords error,
warn and panic are deprecated and should not be used anymore. The
priority defines the severity of the message.
An asterisk ("*") stands for all facilities or all priorities,
depending on where it is used (before or after the period). The
keyword none stands for no priority of the given facility.
You can specify multiple facilities with the same priority pattern in
one statement using the comma (",") operator. You may specify as much
facilities as you want. Remember that only the facility part from such
a statement is taken, a priority part would be skipped.
Multiple selectors may be specified for a single action using the
semicolon (";") separator. Remember that each selector in the
selector field is capable to overwrite the preceding ones. Using this
behavior you can exclude some priorities from the pattern.
Então, isso é bastante compreensível, mas e o caminho do arquivo à direita. Pode ser apenas um caminho ou caminho com |
ou -
antes (ou talvez até outra coisa). Qual é a diferença entre os três?
