Listener log rotation script(generic)- it works for what ever listeners currently running on the server.

#!/bin/bash
##Listener log rotation##
LSNR_NAME=`ps -ef|grep tnslsnr|grep -v grep|awk '{print $9}'`
for i in $LSNR_NAME; do
ORACLE_HOME=`ps -ef|grep tnslsnr|grep -v grep|awk '{print $8}'| rev | cut -d'/' -f3- | rev`
export PATH=$ORACLE_HOME/bin:$PATH
LSNR_LOG_LOC=`lsnrctl status ${LSNR_NAME} | grep "Listener Log File" | awk '{ print $4 }'|rev|cut -d '/' -f2-|rev`
find $LSNR_LOG_LOC -name 'log_*' -mtime +5 -exec rm -f {} \;
cd ../trace
LSNR_LOG_FILE=`ls -lrt *.log|awk '{print $9}'`
find -name '*.gz' -mtime +10 -exec rm -f {} \;
tar -cvzf $LSNR_LOG_FILE.`date '+%d%m%Y%H%M%S'`.tar.gz $LSNR_LOG_FILE
cat /dev/null > $LSNR_LOG_FILE
done
