LOGGER(1) BSD General Commands Manual LOGGER(1) 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 op- tion is specified, logger tries to send the message to all ad- dresses. -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. This option is ignored when a message is also specified. -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 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 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") compati- ble.
