-f config_file|
Instruct newsyslog to use config_file instead of /etc/newsyslog.conf for its configuration
file.
| -a directory|
Specify a directory into which archived log files will be written. If a relative path is
given, it is appended to the path of each log file and the resulting path is used as the direc-
tory into which the archived log for that log file will be written. If an absolute path is
given, all archived logs are written into the given directory. If any component of the path
directory does not exist, it will be created when newsyslog is run.
| -d directory |
Specify a directory which all log files will be relative to. To allow archiving of logs out-
side the root, the directory passed to the -a option is unaffected.
| -v | Place newsyslog in verbose mode. In this mode it will print out each log and its reasons for
either trimming that log or skipping it.
| -n| Cause newsyslog not to trim the logs, but to print out what it would do if this option were not
specified.
| -r | Remove the restriction that newsyslog must be running as root. Of course, newsyslog will not
be able to send a HUP signal to syslogd(8) so this option should only be used in debugging.
| -s | Specify that newsyslog should not send any signals to any daemon processes that it would nor-
mally signal when rotating a log file. For any log file which is rotated, this option will
usually also mean the rotated log file will not be compressed if there is a daemon which would
have been signalled without this option. However, this option is most likely to be useful when
specified with the -R option, and in that case the compression will be done.
| -C | If specified once, then newsyslog will create any log files which do not exist, and which have
the C flag specified in their config file entry. If specified multiple times, then newsyslog
will create all log files which do not already exist. If log files are given on the command-
line, then the -C or -CC will only apply to those specific log files.
| -F | Force newsyslog to trim the logs, even if the trim conditions have not been met. This option
is useful for diagnosing system problems by providing you with fresh logs that contain only the
problems.
| -N |
Do not perform any rotations. This option is intended to be used with the -C or -CC options
when creating log files is the only objective.
| -R tagname|
Specify that newsyslog should rotate a given list of files, even if trim conditions are not met
for those files. The tagname is only used in the messages written to the log files which are
rotated. This differs from the -F option in that one or more log files must also be specified,
so that newsyslog will only operate on those specific files. This option is mainly intended
for the daemons or programs which write some log files, and want to trigger a rotate based on
their own criteria. With this option they can execute newsyslog to trigger the rotate when
they want it to happen, and still give the system administrator a way to specify the rules of
rotation (such as how many backup copies are kept, and what kind of compression is done). When
a daemon does execute newsyslog with the -R option, it should make sure all of the log files
are closed before calling newsyslog, and then it should re-open the files after newsyslog
returns. Usually the calling process will also want to specify the -s option, so newsyslog
will not send a signal to the very process which called it to force the rotate. Skipping the
signal step will also mean that newsyslog will return faster, since newsyslog normally waits a
few seconds after any signal that is sent.
