logger -- make entries in the system log
logger [-cins] [-d SD] [-f file] [-m msgid] [-p pri] [-t tag]
logger provides a shell command interface to the syslog(3) system log
-c Log to console as a fallback (LOG_CONS): if the message cannot
be passed to syslogd(8), the message is written to
-d sd Log this in the structured data (SD) field. (sd has to be
passed as one argument and will require careful quoting when
used from the shell.)
-f file Log the specified file.
-i Log the process id of the logger process with each line
-m msgid The MSGID used for the message.
-n Open log file immediately (LOG_NDELAY).
-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
-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.
The logger utility exits 0 on success, and >0 if an error occurs.
logger System rebooted
logger -p local0.notice -t HOSTIDM -f /dev/idmc
The logger utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
