NAME
logger - a shell command interface to the
syslog(3)
system log module
SYNOPSIS
logger [-isd ] [-f
file ] [-p pri ] [-t tag ]
[-u socket ] [message ... ]
DESCRIPTION
Logger makes entries in the system log.
It 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 info
rmational level in the local3 facility. The default
is ``user.notice.''
- -t tag
- Mark every line in the log with the specified tag
- -u sock
- Write to socket as specified with socket instead of
builtin syslog routines.
- -d
- Use a datagram instead of a stream connection to this socket.
- --
- End the argument list. This is to allow the message to
start with a hyphen (-).
- 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.
Valid facility names are: auth, authpriv (for security
information of a sensitive nature), cron, daemon, ftp, kern, lpr,
mail, news, security (deprecated synonym for auth), syslog, user,
uucp, and local0 to local7, inclusive.
Valid level names are): alert, crit, debug, emerg, err, error
(deprecated synonym for err), info, notice, panic (deprecated
synonym for emerg), warning, warn (deprecated synonym for warning).
For the priority order and intended purposes of these levels, see
syslog(3).
