When it is executed it archives log files if necessary. If a log file is determined to require archiving, .Nm rearranges the files so that .Dq Va logfile is empty, .Dq Va logfile Ns Li \&.0 has the last period's logs in it, .Dq Va logfile Ns Li \&.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 A log can be archived for three reasons: .Bl -enum -offset indent .It It is larger than the configured size (in kilobytes). .It A configured number of hours have elapsed since the log was last archived. .It This is the specific configured hour for rotation of the log. .El .Pp The granularity of .Nm 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, and mode three (above) assumes that this is so. .Sh OPTIONS The following options can be used with .Nm : .Bl -tag -width indent .It Fl f Ar config_file Instruct .Nm to use .Ar config_file instead of .Pa /etc/newsyslog.conf for its configuration file. .It Fl a Ar directory Specify a .Ar 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 directory 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 .Ar directory . If any component of the path .Ar directory does not exist, it will be created when .Nm is run. .It Fl d Ar directory Specify a .Ar directory which all log files will be relative to. To allow archiving of logs outside the root, the .Ar directory passed to the .Fl a option is unaffected. .It Fl v Place .Nm in verbose mode. In this mode it will print out each log and its reasons for either trimming that log or skipping it. .It Fl n Cause .Nm not to trim the logs, but to print out what it would do if this option were not specified. .It Fl r Remove the restriction that .Nm must be running as root. Of course, .Nm will not be able to send a HUP signal to .Xr syslogd 8 so this option should only be used in debugging. .It Fl s Specify that .Nm should not send any signals to any daemon processes that it would normally 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 .Fl R option, and in that case the compression will be done. .It Fl C If specified once, then .Nm will create any log files which do not exist, and which have the .Sy C flag specified in their config file entry. If specified multiple times, then .Nm will create all log files which do not already exist. If log files are given on the command-line, then the .Fl C or .Fl CC will only apply to those specific log files. .It Fl F Force .Nm 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. .It Fl N Do not perform any rotations. This option is intended to be used with the .Fl C or .Fl CC options when creating log files is the only objective. .It Fl P Prevent further action if we should send signal but the .Dq pidfile is empty or does not exist. .It Fl R Ar tagname Specify that .Nm should rotate a given list of files, even if trim conditions are not met for those files. The .Ar tagname is only used in the messages written to the log files which are rotated. This differs from the .Fl F option in that one or more log files must also be specified, so that .Nm 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 .Nm 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 .Nm with the .Fl R option, it should make sure all of the log files are closed before calling .Nm , and then it should re-open the files after .Nm returns. Usually the calling process will also want to specify the .Fl s option, so .Nm will not send a signal to the very process which called it to force the rotate. Skipping the signal step will also mean that .Nm will return faster, since .Nm normally waits a few seconds after any signal that is sent. +.It Fl S Ar pidfile +Use +.Ar pidfile +as +.Xr syslogd 8 Ns 's +pidfile. .El .Pp If additional command line arguments are given, .Nm will only examine log files that match those arguments; otherwise, it will examine all files listed in the configuration file. .Sh FILES .Bl -tag -width /etc/newsyslog.confxxxx -compact .It Pa /etc/newsyslog.conf .Nm configuration file .El .Sh COMPATIBILITY Previous versions of the .Nm utility used the dot (``.'') character to distinguish the group name. Beginning with .Fx 3.3 , this has been changed to a colon (``:'') character so that user and group names may contain the dot character. The dot (``.'') character is still accepted for backwards compatibility. .Sh HISTORY The .Nm utility originated from .Nx and first appeared in .Fx 2.2 . .Sh AUTHORS .An Theodore Ts'o , MIT Project Athena .Pp Copyright 1987, Massachusetts Institute of Technology .Sh "SEE ALSO" .Xr bzip2 1 , .Xr gzip 1 , .Xr syslog 3 , .Xr newsyslog.conf 5 , .Xr chown 8 , .Xr syslogd 8 .Sh BUGS Does not yet automatically read the logs to find security breaches.

Configuration may designate that logs are rotated based on size, last rotation time, or time of day. The .Nm file can also be used to designate secure permissions to log files at rotation time. During initialization, .Xr newsyslog 8 reads a configuration file, normally .Pa /etc/newsyslog.conf , to determine which logs may potentially be rotated and archived. Each line has five mandatory fields and four optional fields, separated with whitespace. Blank lines or lines beginning with .Ql # are ignored. If .Ql # is placed in the middle of the line, the .Ql # character and the rest of the line after it is ignored. To prevent special meaning, the .Ql # character may be escaped with .Ql \e ; in this case preceding .Ql \e is removed and .Ql # is treated as an ordinary character. The fields of the configuration file are as follows: .Bl -tag -width indent .It Ar logfile_name Name of the system log file to be archived, or the literal string .Dq Aq Li default . The special default entry will only be used if a log file name is given as a command line argument to .Xr newsyslog 8 , and if that log file name is not matched by any other line in the configuration file. .It Ar owner : Ns Ar group This optional field specifies the owner and group for the archive file. The .Ql \&: is essential regardless if the .Ar owner or .Ar group field is left blank or contains a value. The field may be numeric, or a name which is present in .Pa /etc/passwd or .Pa /etc/group . .It Ar mode Specify the file mode of the log file and archives. .It Ar count Specify the maximum number of archive files which may exist. This does not consider the current log file. .It Ar size When the size of the log file reaches .Ar size in kilobytes, the log file will be trimmed as described above. If this field contains an asterisk .Pq Ql * , the log file will not be trimmed based on size. .It Ar when The .Ar when field may consist of an interval, a specific time, or both. If the .Ar when field contains an asterisk .Pq Ql * , log rotation will solely depend on the contents of the .Ar size field. Otherwise, the .Ar when field consists of an optional interval in hours, usually followed by an .So Li \&@ Sc Ns No -sign and a time in restricted .Tn ISO 8601 format. Additionally, the format may also be constructed with a .Ql $ sign along with a rotation time specification of once a day, once a week, or once a month. .Pp If a time is specified, the log file will only be trimmed if .Xr newsyslog 8 is run within one hour of the specified time. If an interval is specified, the log file will be trimmed if that many hours have passed since the last rotation. When both a time and an interval are specified then both conditions must be satisfied for the rotation to take place. .Pp There is no provision for the specification of a timezone. There is little point in specifying an explicit minutes or seconds component in the current implementation, since the only comparison is .Dq within the hour . .Pp .Sy ISO 8601 restricted time format : .Pp The lead-in character for a restricted .Tn ISO 8601 time is an .Ql @ sign. The particular format of the time in restricted .Tn ISO 8601 is: .Sm off .Oo .Op Oo Oo Oo Va cc Oc Va yy Oc Va mm Oc Va dd .Oo .Li T .Op Va hh Oo Va mm Oo Va ss Oc Oc Oc .Oc . .Sm on Optional date fields default to the appropriate component of the current date; optional time fields default to midnight; hence if today is January 22, 1999, the following date specifications are all equivalent: .Pp .Bl -item -compact -offset indent .It .Sq Li 19990122T000000 .It .Sq Li 990122T000000 .It .Sq Li 0122T000000 .It .Sq Li 22T000000 .It .Sq Li T000000 .It .Sq Li T0000 .It .Sq Li T00 .It .Sq Li 22T .It .Sq Li T .It .Sq Li \& .El .Pp .Sy Day, week, and month time format: .Pp The lead-in character for day, week, and month specification is a .Ql $ sign. The particular format of day, week, and month specification is: .Op Li D Ns Va hh , .Op Li W Ns Va w Ns Op Li D Ns Va hh , and .Op Li M Ns Va dd Ns Op Li D Ns Va hh , respectively. Optional time fields default to midnight. The ranges for day and hour specifications are: .Pp .Bl -tag -width indent -offset indent -compact .It Ar hh hours, range 0..23 .It Ar w day of week, range 0..6, 0 = Sunday .It Ar dd day of month, range 1..31, or one of the letters .Ql L or .Ql l to specify the last day of the month. .El .Pp Some examples: .Pp .Bl -tag -width indent -offset indent -compact .It Li $D0 rotate every night at midnight (same as .Li @T00 ) .It Li $D23 rotate every day at 23:00 (same as .Li @T23 ) .It Li $W0D23 rotate every week on Sunday at 23:00 .It Li $W5D16 rotate every week on Friday at 16:00 .It Li $M1D0 rotate at the first day of every month at midnight (i.e., the start of the day; same as .Li @01T00 ) .It Li $M5D6 rotate on every 5th day of month at 6:00 (same as .Li @05T06 ) .El .It Ar flags This optional field is made up of one or more characters that specify any special processing to be done for the log files matched by this line. The following are valid flags: .Bl -tag -width indent .It Cm B indicates that the log file is a binary file, or has some special format. Usually .Xr newsyslog 8 inserts an .Tn ASCII message into a log file during rotation. This message is used to indicate when, and sometimes why the log file was rotated. If .Cm B is specified, then that informational message will not be inserted into the log file. .It Cm C indicates that the log file should be created if it does not already exist, and if the .Fl C option was also specified on the command line. .It Cm D indicates that .Xr newsyslog 8 should set the .Dv UF_NODUMP flag when creating a new version of this log file. This option would affect how the .Xr dump 8 command treats the log file when making a file system backup. .It Cm G indicates that the specified .Ar logfile_name is a shell pattern, and that .Xr newsyslog 8 should archive all filenames matching that pattern using the other options on this line. See .Xr glob 3 for details on syntax and matching rules. .It Cm J indicates that .Xr newsyslog 8 should attempt to save disk space by compressing the rotated log file using .Xr bzip2 1 . .It Cm N indicates that there is no process which needs to be signaled when this log file is rotated. .It Cm U indicates that the file specified by .Ar path_to_pid_file will contain the ID for a process group instead of a process. This option also requires that the first line in that file be a negative value to distinguish it from a process ID. .It Cm Z indicates that .Xr newsyslog 8 should attempt to save disk space by compressing the rotated log file using .Xr gzip 1 . .It Fl a minus sign will not cause any special processing, but it can be used as a placeholder to create a .Ar flags field when you need to specify any of the following fields. .El .It Ar path_to_pid_file This optional field specifies the file name containing a daemon's process ID or to find a group process ID if the .Cm U flag was specified. If this field is present, a .Ar signal_number -is sent the process ID contained in this file. -If this field is not present, then a +is sent to the process ID contained in this file. +If this field is not present and the +.Cm N +flag has not been specified, then a .Dv SIGHUP signal will be sent to -.Xr syslogd 8 , -unless the -.Cm N -flag has been specified. +.Xr syslogd 8 +or to the process id found in the file specified by +.Xr newsyslog 8 Ns 's +.Fl S +switch. This field must start with .Ql / in order to be recognized properly. .It Ar signal_number This optional field specifies the signal number that will be sent to the daemon process (or to all processes in a process group, if the .Cm U flag was specified). If this field is not present, then a .Dv SIGHUP signal will be sent. .El .Sh SEE ALSO .Xr bzip2 1 , .Xr gzip 1 , .Xr syslog 3 , .Xr chown 8 , .Xr newsyslog 8 , .Xr syslogd 8 .Sh HISTORY This manual page first appeared in .Fx 4.10 .
