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 pri-
		     ority 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  charac-
		  ters.

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.
