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 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). For the priority order and intended purposes of these levels, see syslog(3). EXAMPLES

The logger command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. 4.3 Berkeley Distribution June 6, 1993 4.3 Berkeley Distribution

logger - add entries to the system log SYNOPSIS
logger [-i] [-f file] [-p priority] [-t tag] [message] ... DESCRIPTION
The logger command provides a method for adding one-line entries to the system log file from the command line. One or more message argu- ments can be given on the command line, in which case each is logged immediately. If this is unspecified, either the file indicated with -f or the standard input is added to the log. Otherwise, a file can be specified, in which case each line in the file is logged. If neither is specified, logger reads and logs messages on a line-by-line basis from the standard input. OPTIONS
The following options are supported: -ffile Uses the contents of file as the message to log. -i Logs the process ID of the logger process with each line. -ppriority Enters the message with the specified priority. The message priority can be specified numerically, or as a facility.level pair. For example, `-p local3.info' assigns the message priority to the info level in the local3 facility. The default priority is user.notice. -ttag Marks each line added to the log with the specified tag. OPERANDS
The following operand is supported: message One of the string arguments whose contents are concatenated together, in the order specified, separated by single space characters. EXAMPLES
Example 1: Examples of the logger command The following example: example% logger System rebooted logs the message `System rebooted' to the default priority level notice to be treated by syslogd as are other messages to the facility user. The next example: example% logger -p local0.notice -t HOSTIDM -f /dev/idmc reads from the file /dev/idmc and logs each line in that file as a message with the tag `HOSTIDM' at priority level notice to be treated by syslogd as are other messages to the facility local0.
