NAME
logger -- make entries in the system log SYNOPSIS
logger [-46Ais] [-f file] [-h host] [-P port] [-p pri] [-t tag] [message ...] DESCRIPTION
The logger utility provides a shell command interface to the syslog(3) system log module. The following options are available: -4 Force logger to use IPv4 addresses only. -6 Force logger to use IPv6 addresses only. -A By default, logger tries to send the message to only one address, even if the host has more than one A or AAAA record. If this option is specified, logger tries to send the message to all addresses. -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 Read the contents of the specified file into syslog. -h host Send the message to the remote system host instead of logging it locally. -P port Send the message to the specified port number on a remote system, which can be specified as a service name or as a decimal number. The default is ``syslog''. If an unknown service name is used, logger prints a warning and falls back to port 514. -p pri Enter the message with the specified priority. The priority may be specified numerically or as a ``facility.level'' pair. For exam- ple, ``-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 rather than the default of current login name. message Write the message to log; if not specified, and the -f flag is not provided, standard input is logged. EXIT STATUS
The logger utility exits 0 on success, and >0 if an error occurs. EXAMPLES
logger System rebooted logger -p local0.notice -t HOSTIDM -f /dev/idmc SEE ALSO
syslog(3), syslogd(8) STANDARDS
The logger command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. BSD

NAME
logger -- a shell command interface to the syslog(3) system log module SYNOPSIS
logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...] DESCRIPTION
Logger makes entries in the system log. It 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 (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 (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). EXAMPLES
logger System rebooted logger -p local0.notice -t HOSTIDM -f /dev/idmc SEE ALSO
syslog(3), syslogd(8) STANDARDS
The logger command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. AVAILABILITY
The logger command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. 4.3 Berkeley Distribution June 6, 1993 4.3 Berkeley Distribution
