NAME

       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.
