STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

OPTIONS

       [Tru64  UNIX]  Logs  the  informational message to the binary event logger instead of the syslog() subroutine and enters information in the
       binary event log file.  The uerf command with the -r 250 option reports the informational messages that are in the binary event	log  file,
       which  is  used	for  system maintenance and troubleshooting.  The -b option cannot be used with any other options.  [Tru64 UNIX]  Logs all
       lines in file.  [Tru64 UNIX]  Logs the process ID (PID) of the logger process with each line.  [Tru64 UNIX]  Enters the	message  with  the
       specified priority and, if specified, from the specified facility.

	      [Tru64 UNIX]  You can specify priority as either an alphabetic string or its integer equivalent.	You can specify the following val-
	      ues for the priority variable: [Tru64 UNIX]  (0) [Tru64 UNIX]  The system is unusable.  (0) [Tru64 UNIX]	Action must be taken imme-
	      diately.	 (1)  [Tru64  UNIX]  Critical  conditions.   (2)  [Tru64 UNIX]	Error conditions.  (3) [Tru64 UNIX]  (3) [Tru64 UNIX]  (4)
	      [Tru64 UNIX]  Warning conditions.  (4) [Tru64 UNIX]  Normal but significant condition.  (5) [Tru64 UNIX]	Informational. (6)  [Tru64
	      UNIX]  Debug-level messages.  (7)

	      [Tru64  UNIX]  You  can  also  specify  a value for the facility variable, which indicates the source of the event.  You can specify
	      facility as either an alphabetic string or its integer equivalent.  The integer values appear in parentheses.  You can  specify  the
	      following  values for the facility variable: [Tru64 UNIX]  Kernel messages. (0) [Tru64 UNIX]  Random user-level messages. (8) [Tru64
	      UNIX]  Mail system. (16) [Tru64 UNIX]  System daemons. (24) [Tru64 UNIX]	Security/authorization messages.  (32) [Tru64  UNIX]  (32)
	      [Tru64  UNIX]  Messages  syslogd	generates internally.  (40) [Tru64 UNIX]  Line printer subsystem.  (48) [Tru64 UNIX]  Network news
	      subsystem.  (56) [Tru64 UNIX]  UUCP subsystem.  (64) [Tru64 UNIX]  Clock	daemon.   (72)	[Tru64	UNIX]  (128)  [Tru64  UNIX]  (136)
	      [Tru64  UNIX]  (144)  [Tru64  UNIX]  (152)  [Tru64  UNIX]  (160)	[Tru64 UNIX]  (168) [Tru64 UNIX]  (176) [Tru64 UNIX]  (184) [Tru64
	      UNIX]  Precedes each entry in the log with tag.

OPERANDS

       You can specify the message to be used for entries on the command line or with the -f file option, which specifies that each line  in  file
       be logged as an entry.  If you do not specify message or -f, logger reads standard input.

DESCRIPTION

       The logger command makes the specified entries in the system log file.

       The logger command provides a program and shell script interface to the syslog() subroutine.  The file in which entries are made depends on
       the current system log configuration; see syslog and syslogd for more information.

NOTES

       The effects of the environment variable LC_MESSAGES apply only to diagnostic messages generated by logger, and not to any messages  written
       by the use of the command.

EXIT STATUS

       The following exit values are returned: Successful completion.  An error occurred.

EXAMPLES

       To log the system reboot, including the process ID of the process running logger,  enter: logger -i System rebooted To log each line in the
       file build.events with the tag trial build preceding them, enter: logger -f build.events -t "trial build" The following commands are equiv-
       alent and enter events of warning priority to the log: logger -p warning

       logger -p 4 The following commands are equivalent and enter events from the daemon facility of warning priority: logger -p daemon.warning

       logger -p 24.4 To specify the debug priority with a priority name, enter: logger -p debug my message

	      To  specify  the	debug  priority  with a priority number, enter: logger -p 7 my message To specify both debug priority and the user
	      facility, enter: logger -p user.debug my message

	      To specify the same facility/priority pair using numeric values, enter: logger -p 8.7 my message

	      You can also combine alphabetic and numeric specifications: logger -p user.7 my message logger -p 8.debug my message

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of logger: Provides a default value for the  internationalization  variables  that
       are  unset  or null. If LANG is unset or null, the corresponding value from the default locale is used.	If any of the internationalization
       variables contain an invalid setting, the utility behaves as if none of the variables had been defined.	 If  set  to  a  non-empty  string
       value,  overrides the values of all the other internationalization variables.  Determines the locale for the interpretation of sequences of
       bytes of text data as characters (for example, single-byte as opposed to multi-byte characters in arguments).  Determines  the  locale  for
       the format and contents of diagnostic messages written to standard error.  Determines the location of message catalogues for the processing
       of LC_MESSAGES.
