LOGGER(1) BSD General Commands Manual LOGGER(1)

NAME

logger — make entries in the system log

SYNOPSIS

logger [−isd] [−f file] [−p pri] [−t tag] [−u socket] [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.

−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).

EXAMPLES

logger System rebooted

logger −p local0.notice −t HOSTIDM −f /dev/idmc

SEE ALSO
