NAME
       logger - a shell command interface to the syslog(3) system log module

SYNOPSIS
       logger [options] [message]

DESCRIPTION
       logger  makes  entries  in the system log.  It provides a shell command
       interface to the syslog(3) system log module.

OPTIONS
       -d, --udp
	      Use datagram (UDP) instead  of  the  default  stream  connection
	      (TCP).

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

       -f, --file file
	      Log  the	contents of the specified file.	 This option cannot be
	      combined with a command-line message.

       -h, --help
	      Display a help text and exit.

       -n, --server server
	      Write to the specified remote syslog server using UDP instead of
	      to the builtin syslog routines.

       -P, --port port
	      Use the specified UDP port.  The default port number is 514.

       -p, --priority priority
	      Enter the message into the log with the specified priority.  The
	      priority may be specified numerically  or	 as  a	facility.level
	      pair.   For example, -p local3.info logs the message as informa‐
	      tional in the local3 facility.  The default is user.notice.

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

       -t, --tag tag
	      Mark every line to be logged with the specified tag.

       -u, --socket socket
	      Write  to	 the specified socket instead of to the builtin syslog
	      routines.

       -V, --version
	      Display version information and exit.

       --     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  (can't  be generated from
       user  process),	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 (depre‐
       cated synonym for  err), info, notice, panic  (deprecated  synonym  for
       emerg), warning, warn (deprecated synonym for warning).	For the prior‐
       ity order and intended purposes of these levels, see syslog(3).

EXAMPLES
       logger System rebooted
       logger -p local0.notice -t HOSTIDM -f /dev/idmc
       logger -n loghost.example.com System rebooted

STANDARDS
       The logger command is expected to be IEEE Std 1003.2  ("POSIX.2")  com‐
       patible.

AVAILABILITY

       from Linux Kernel  Archive  ⟨ftp://ftp.kernel.org/pub/linux/utils/util-
