logger(1B) SunOS/BSD Compatibility Package Commands logger(1B)NAMElogger - add entries to the system log
SYNOPSIS
/usr/ucb/logger [-f filename] [-i] [-p priority] [-t tag] mm
[message]...
DESCRIPTION
The logger utility provides a method for adding one-line entries to the
system log file from the command line. One or more message arguments
can be given on the command line, in which case each is logged immedi‐
ately. If message is unspecified, either the file indicated with -f or
the standard input is added to the log. Otherwise, a filename 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:
-i Log the process ID of the logger process with each line.
-f filename Use the contents of filename as the message to log.
-p priority Enter the message with the specified priority. The mes‐
sage 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 priority is user.notice.
-t tag Mark each line added to the log with the specified tag.
EXAMPLES
Example 1 Logging a message
The command:
example% logger System rebooted
will log the message `System rebooted' to the facility at priority
notice to be treated by syslogd as other messages to the facility
notice are.
Example 2 Logging messages from a file
The command:
example% logger-p local0.notice -t HOSTIDM -f /dev/idmc
will read from the file /dev/idmc and will log each line in that file
as a message with the tag `HOSTIDM' at priority notice to be treated by
syslogd as other messages to the facility local0 are.
