Thanks cfajohnson, but that back slash prevents LINENO from ever being expanded:

joe@rose:~$ MYNAME=joe
joe@rose:~$ MYPID=$$
joe@rose:~$ LOGGER="/usr/bin/logger -t $MYNAME[$MYPID](\$LINENO) -p daemon.error"
joe@rose:~$ echo 'test' | $LOGGER
joe@rose:~$ tail -1 /var/log/daemon.log
Feb 18 01:40:27 rose joe[26479]($LINENO): test

Am I missing something?
