Manual Pages  — LOGGER

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. This option is ignored when a message is also specified.
-H hostname
	Set the hostname in the header of the message to specified value. If not specified, host part of gethostname(3) will be used.
-h host
	Send the message to the remote system host instead of logging it locally. Note that logger currently supports AF_INET (IPv4), AF_INET6 (IPv6), and AF_LOCAL (Unix-domain socket) address families. The following address formats are valid in host:

AF_INET	192.168.2.1
AF_INET6	2001:db8::1
AF_LOCAL	/var/run/log

-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, "-plocal3.info" logs the message(s) as informational level in the local3 facility. The default is "user.notice".
-S addramp;:port
	Specify source address and/or source port when using -h option. The same address will be used for all of the remote addresses when -A flag is enabled. Note that a numeric IPv6 address in addr must be enclosed with "amp;[" and "amp;]".
-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.
