SUNWcsu
The logger command 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 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.
The following options are supported:
- -f file
- Use the contents
of file as the message to log.
- -i
- Log the process ID
of the logger process
with each line.
- -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.
The following
operand is supported:
- message
- One of the string arguments whose contents
are concatenated together, in the order specified, separated by single
space characters.
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.
