logger
LOGGER(1) BSD General Commands Manual LOGGER(1)NAME
logger -- make entries in the system log
SYNOPSIS
logger [-is] [-f file] [-p pri] [-t tag] [message ...]
DESCRIPTION
Logger provides a shell command interface to the syslog(3) system log module.
Options:
-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.
-f file Log the specified file.
-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.
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.
EXAMPLES

logger -p local0.notice -t HOSTIDM -f /dev/idmc
SEE ALSO syslog(3), syslogd(8)STANDARDS
The logger utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
