       logger - add entries to the system log

       logger [-i] [-f file] [-p priority] [-t tag] [message] ...

       The  logger  command  provides a method for adding one-line entries to the system log file
       from the command line. One or more message arguments 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.

       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.

       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.

       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.

       See  environ(5)	for  descriptions  of the following environment variables that affect the
       execution of logger: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.
