logger — a shell command interface to the syslog(3) system log module
logger [−isd] [ −f file ] [ −p pri ] [ −t tag ] [ −u socket ] [ message... ]
Logger makes
entries in the system log. It provides a shell command
interface to the syslog3 system
log module.
Options:
−iLog the process id of the logger process with each line.
−sLog the message to standard error, as well as the system log.
−f fileLog the specified file.
−p priEnter 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 tagMark every line in the log with the specified
tag.
−u sockWrite to socket as specified with socket instead of builtin
syslog routines.
−dUse 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 (−).
messageWrite 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).
The logger command is expected to be IEEE Std 1003.2 (“POSIX.2”) compatible.
