logger -- make entries in the system log
logger [-46Ais] [-f file] [-h host] [-p pri] [-t tag] [message ...]
The logger utility provides a shell command interface to the syslog(3)
system log module.
The following options are available:
-4 Force logger to use IPv4 addresses only.
-6 Force logger to use IPv6 addresses only.
-A By default, logger tries to send the message to only one address,
even if the host has more than one A or AAAA record. If this
option is specified, logger tries to send the message to all
-i Log the process id of the logger process with each line.
-s Log the message to standard error, as well as the system log.
Log the specified file.
Send the message to the remote system host instead of logging it
-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.''
-t tag Mark every line in the log with the specified tag.
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.
