     logger -- make entries in the system log

SYNOPSIS    [Toc]    [Back]

     logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]

DESCRIPTION    [Toc]    [Back]

     Logger provides a shell command interface to the syslog(3) system log
     module.

     Options:

     -i       Log the process id of the logger process with each line.

     -s       Log the message to standard error, as well as the system log.

     -f file  Log the specified file.

     -p pri   Enter the message with the specified priority.  The priority may
	      be specified numerically or as a ``facility.level'' pair.  For
	      example, ``-p local3.info'' logs the message(s) as informational
	      level in the local3 facility.  The default is ``user.notice.''

     -t tag   Mark every line in the log with the specified tag.

     -u sock  Write to socket as specified with socket instead of builtin syslog
 routines.

     -d       Use a datagram instead of a stream connection to this socket.

     --       End the argument list. This is to allow the message to start
	      with a hyphen (-).

     message  Write the message to log; if not specified, and the -f flag is
	      not provided, standard input is logged.

     The logger utility exits 0 on success, and >0 if an error occurs.

     Valid facility names are: auth, authpriv (for security information of a
     sensitive nature), cron, daemon, ftp, kern, lpr, mail, news, security
     (deprecated synonym for auth), syslog, user, uucp, and local0 to local7,
     inclusive.

     Valid level names are): alert, crit, debug, emerg, err, error (deprecated
     synonym for err), info, notice, panic (deprecated synonym for emerg),
     warning, warn (deprecated synonym for warning).  For the priority order
     and intended purposes of these levels, see syslog(3).
