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 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

logger - add entries to the system log SYNOPSIS
logger [-i] [-f file] [-p priority] [-t tag] [message] ... DESCRIPTION
The logger command provides a method for adding one-line entries to the system log file from the command line. One or more message argu- ments can be given on the command line, in which case each is logged immediately. If this is unspecified, either the file indicated with -f or the standard input is added to the log. Otherwise, a file can be specified, in which case each line in the file is logged. If neither is specified, logger reads and logs messages on a line-by-line basis from the standard input. OPTIONS
The following options are supported: -ffile Uses the contents of file as the message to log. -i Logs the process ID of the logger process with each line. -ppriority Enters the message with the specified priority. The message priority can be specified numerically, or as a facility.level pair. For example, `-p local3.info' assigns the message priority to the info level in the local3 facility. The default pri- ority is user.notice. -ttag Marks each line added to the log with the specified tag. OPERANDS
The following operand is supported: message One of the string arguments whose contents are concatenated together, in the order specified, separated by single space charac- ters. EXAMPLES
Example 1 Examples of the logger command The following example: example% logger System rebooted logs the message `System rebooted' to the default priority level notice to be treated by syslogd as are other messages to the facility user. The next example: example% logger -p local0.notice -t HOSTIDM -f /dev/idmc reads from the file /dev/idmc and logs each line in that file as a message with the tag `HOSTIDM' at priority level notice to be treated by syslogd as are other messages to the facility local0. ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of logger: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. EXIT STATUS
