Q on <user> of syslog message generated by logger command
Generally(at least on AIX5.3, Solaris9, OS X)'logger' command would create syslog messages which carry <login name> . On Solaris9, I have experienced two circumstances in which 'logname' command fails. In this circumstance I saw the 'logger' command generated syslog messages which carry alternatively <real or effective user name> instead of the <login name> that is seemingly unable for the logger to retrieve. One of the circumstances is on shells(either ksh or csh) running on the emacs buffer. For the other one, sorry, I can not tell you here.
Are there any ways by which we can let the logger to create syslog messages with <real or effective user name> instead of <login name>?

Thanks,
masaki

correction: replaced "effective" with "real or effective"

logger

logger(1B)					     SunOS/BSD Compatibility Package Commands						logger(1B)

NAME

       logger - add entries to the system log

SYNOPSIS

       /usr/ucb/logger [-f filename] [-i] [-p priority] [-t tag] mm
	    [message]...

DESCRIPTION

       The  logger  utility  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 message is unspecified, either the file indicated with
       -f  or  the  standard  input is added to the log. Otherwise, a filename 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:

       -i	      Log the process ID of the logger process with each line.

       -f filename    Use the contents of filename as the message to log.

       -p priority    Enter 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.

       -t tag	      Mark each line added to the log with the specified tag.

EXAMPLES

       Example 1 Logging a message

       The command:

	 example% logger System rebooted

       will log the message `System rebooted' to the facility at priority notice to be treated by syslogd as other messages to the facility notice
       are.

       Example 2 Logging messages from a file

       The command:

	 example% logger -p local0.notice -t HOSTIDM -f /dev/idmc

       will  read from the file /dev/idmc and will log each line in that file as a message with the tag `HOSTIDM' at priority notice to be treated
       by syslogd as other messages to the facility local0 are.
