NAME
logger - 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 immediately. 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
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 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.
