logger - add entries to the system log
/usr/ucb/logger [-f filename] [-i] [-p priority] [-t tag] mm
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 stan-
dard 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.
The following options are supported:
-i Log the process ID of the logger process with each
Use the contents of filename as the message to log.
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.
Mark each line added to the log with the specified
Example 1: Logging a message
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
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.
