logger - make entries in the system log
SYNOPSIS
logger [-cis] [-f file] [-p pri] [-t tag] [message ...]
DESCRIPTION
The logger utility provides a shell command interface to the syslog(3)
system log module.
The options are as follows:
-c If unable to pass the message to syslogd(8), attempt to write
the message to the console.
-f file Read from the specified file.
-i Log the process ID of the logger process with each line.
-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".
-s Log the message to standard error, as well as the system log.
-t tag Mark every line in the log with the specified tag.
message Write the message to log; if not specified, and the -f flag is
not provided, standard input is logged.
EXIT STATUS
The logger utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
$ logger System rebooted
$ logger -p local0.notice -t HOSTIDM -f /dev/idmc
