NAME

logger − make entries in the system log

SYNOPSIS

logger [ −t tag ] [ −p pri ] [ −i ] [ −f file ] [ message ... ]

DESCRIPTION

Logger provides a program interface to the syslog(3C) system log module.

A message can be given on the command line, which is logged immediately, or a file is read and each line is logged.  If no file or message is specified, the contents of the standard input are logged. 

Options

−t tag Mark every line in the log with the specified tag.

−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.”

−i Log the process ID of the logger process with each line. 

−f file Log the contents of the specified file. 

message The message to log; if not specified, the −f file or standard input is logged. 

EXAMPLES

This command sends the message "System rebooted" to the syslog daemon:

logger System rebooted

This command sends the output of the users(1) command to the syslog daemon, marked as priority "info" and facility "local0".  The message is tagged with the "USERS":

users | −p local0.info −t USERS

WARNINGS

Logger has no effect if the syslog daemon (syslogd(1M)) is not running on the system.
