When it is executed it archives log files if necessary. If a log file is determined to require archiving, -.I newsyslog +.Nm newsyslog rearranges the files so that ``logfile'' is empty, ``logfile.0'' has the last period's logs in it, ``logfile.1'' has the next to last period's logs in it, and so on, up to a user-specified number of archived logs. Optionally the archived logs can be compressed to save space. -.PP +.Pp A log can be archived because of two reasons. The log file can have grown bigger than a preset size in kilobytes, or a preset number of hours may have elapsed since the last log archive. The granularity of -.I newsyslog -is dependent on how often it is scheduled to run in crontab. Since -the program is quite fast, it may be scheduled to run every hour +.Nm newsyslog +is dependent on how often it is scheduled to run by +.Xr cron 8 . +Since the program is quite fast, it may be scheduled to run every hour without any ill effects. -.PP +.Pp When starting up, -.I newsyslog +.Nm newsyslog reads in a configuration file to determine which logs should be looked at. By default, this configuration file is -.IR /etc/newsyslog.conf . +.Pa /etc/newsyslog.conf . Each line of the file contains information about a particular log file that should be handled by -.IR newsyslog . +.Nm newsyslog . Each line has five mandatory fields and two optional fields, with a whitespace separating each field. Blank lines or lines beginning with ``#'' are ignored. The fields of the configuration file are as follows: -.br - logfile name -.br - owner.group of archives (optional) -.br - mode of logfile & archives -.br - number of archives -.br - size of archives -.br - archive interval -.br - flags (optional) -.PP -The -.I logfile name -entry is the name of the system log file to be archived. -.PP -The optional -.I owner.group -entry specifies an ownership and group for the archive file. -The "." is essential, even if the -.I owner +.Pp +.Bl -tag -width logfile_namexxxx +.It Ar logfile_name +Name of the system log file to be archived. +.It Ar owner.group +Specifies the owner and group for the archive file. +The "." is essential, even if the +.Ar owner or -.I group -field is left blank. The -fields may be numeric, or a name which is looked up in -.I /etc/passwd -or -.IR /etc/group . -.PP -The -.I number of archives -entry specifies the number of archives to be kept besides the log file -itself. -.PP -When the size of the logfile reaches -.I size of -.IR archives , -the logfile becomes trimmed as described above. If this field is -replaced by a ``*'', then the size of the logfile is not taken into -account when determining when to trim the log file. -.PP +.Ar group +field is left blank. The field may be numeric, or a name which is +present in +.Pa /etc/passwd +or +.Pa /etc/group. +.It Ar mode +Specifies the mode of the log file and archives. +.It Ar count +Specifies the number of archive files to be kept +besides the log file itself. +.It Ar size +When the size of the log file reaches +.Ar size , +the log file will be trimmed as described above. If this field +is replaced by a +.Ar * , +then the size of the log file is not taken into account +when determining when to trim the log file. +of archives +.It Ar interval +When +.Ar interval +hours have passed, the log file will be trimmed. If this field is +replaced by a +.Ar * , +then the number of hours since the last time the log was +trimmed will not be taken into consideration. +.It Ar flags +This optional field specifies if the archive should have any +special processing done to the archived log files. The -.I number of hours -entry specifies the time separation between the trimming of the log -file. If this field is replaced by a ``*'', then the number of hours -since the last time the log was trimmed will not be taken into -consideration. -.PP +.Ar Z +flag will make the archive files compress to save space by +using +.Xr gzip 1 . The -.I flags -field specifies if the archives should have any special processing -done to the archived log files. The ``Z'' flag will make the archive -files compressed to save space using /usr/bin/gzip. The ``B'' flag -means that the file is a binary file, and so the ascii message which -.I newsyslog -inserts to indicate the fact that the logs have been turned over -should not be included. -.PP -.SH OPTIONS +.Ar B +flag means that the file is a binary file, and so the ASCII +message which +.Nm +inserts to indicate the fact that the logs have been +turned over should not be included. +.El +.Sh OPTIONS The following options can be used with newsyslog: -.TP -.B \-f \fIconfig-file +.Bl -tag -width indent +.It Fl f Ar config_file instructs newsyslog to use -.I config-file -instead of /etc/newsyslog.conf for its configuration file. -.TP -.B \-v +.Ar config_file +instead of +.Pa /etc/newsyslog.conf +for its configuration file. +.It Fl v places -.I newsyslog +.Nm newsyslog in verbose mode. In this mode it will print out each log and its reasons for either trimming that log or skipping it. -.TP -.B \-n +It Fl n causes -.I newsyslog +.Nm newsyslog not to trim the logs, but to print out what it would do if this option were not specified. -.TP -.B \-r +.It Fl r removes the restriction that -.I newsyslog +.Nm newsyslog must be running as root. Of course, -.I newsyslog +.Nm newsyslog will not be able to send a HUP signal to -.IR syslogd , +.Xr syslogd 8 so this option should only be used in debugging. -.SH FILES -/etc/newsyslog.conf -.SH BUGS +.El +.Sh FILES +.Bl -tag -width /etc/newsyslog.confxxxx -comapct +.It Pa /etc/newsyslog.conf +.Nm newsyslog +configuration file. +.El +.Sh BUGS Doesn't yet automatically read the logs to find security breaches. - - -.SH AUTHOR +.Sh AUTHOR Theodore Ts'o, MIT Project Athena -.br +.Pp Copyright 1987, Massachusetts Institute of Technology -.SH "SEE ALSO" -syslogd(8), syslog(3), gzip(1) -.ns -.sp +.Sh "SEE ALSO" +.Xr gzip 1 , +.Xr syslog 3 , +.Xr syslogd 8 -- cgit v1.1
